Royaume-Uni: la Grande-Bretagne s'apprête à enregistrer sa journée la plus chaude jamais enregistrée

La Grande-Bretagne a connu sa journée la plus chaude hier après avoir enregistré une température de 101,66 ° F dans le Cambridgeshire.

Le Met Office devrait confirmer que le chiffre enregistré dans les jardins botaniques de l’Université de Cambridge est supérieur au 101.3F observé à Faversham, dans le Kent, en août 2003.

Les experts sont en train de valider ces chiffres, qui, s’ils le confirment, seront officiellement le jour le plus chaud en Grande-Bretagne depuis le début des records en 1853.

Les scientifiques vont vérifier le matériel pour voir s'il a été correctement calibré avant de faire l'annonce.

Dans des conditions extrêmes, les trains ont été retardés par crainte que les rails ne se gondolent sous l'effet de la chaleur, tandis que les conseils municipaux ont été obligés d'envoyer du sable qui répandait du sable parce que le tarmac à la surface de la route avait commencé à fondre.

Les températures record britanniques ont été répliquées à travers l'Europe, avec des températures supérieures à 107 ° F enregistrées aux Pays-Bas.

Le Dr Mark McCarthy du Centre national du climat (CNIC) du Met Office a déclaré: «En tant que source officielle de statistiques météorologiques pour le Royaume-Uni, nous prenons très au sérieux la qualité de nos enregistrements.

«Nous parlons d'un nouveau record potentiel pour la température la plus élevée enregistrée au Royaume-Uni et nous devons donc étudier de manière approfondie l'observation avec nos partenaires du jardin botanique de l'université de Cambridge, par le biais d'analyses statistiques et en visitant le site et les équipements et en y veillant. n'y a pas de problèmes potentiels.

Le Met Office indique que les enregistrements météorologiques ne sont utilisés que sur les sites d’observation météorologique avec des instruments étalonnés et standard et une exposition soigneusement surveillée.

L'organisation dispose d'observations de stations individuelles dans une base de données numérique remontant à 1853, mais il existe également des enregistrements papier historiques qui remontent encore plus loin.

Le Met Office a annoncé aujourd'hui qu'il vérifiait un chiffre provisoire enregistré jeudi au Botanic Garden de l'Université de Cambridge, mais que cela nécessiterait un «contrôle de la qualité et une analyse» au cours des prochains jours (photo, l'annonce)

Alors que certaines parties de l'Europe sont restées chaudes vendredi, ce n'était rien comparé à la journée record de jeudi, qui a vu l'Allemagne, le Luxembourg, la Belgique et les Pays-Bas enregistrer leurs journées les plus chaudes (températures à la surface illustrées jeudi; les zones blanches indiquent des nuages)

Révélant les températures provisoirement enregistrées, un porte-parole du Met Office a déclaré: "Aujourd'hui, l'équipe d'observation du Met Office a reçu un nouveau chiffre provisoire de 101.66F (38.7C) du jardin botanique de l'université de Cambridge.

«La température la plus élevée enregistrée pour le Royaume-Uni est de 101,3 ° F (38,5 ° C), enregistrée à Faversham en août 2003.

«La température enregistrée hier au jardin botanique de l'université de Cambridge nécessitera un contrôle de la qualité et une analyse au cours des prochains jours. Si elle est validée, elle deviendra la température la plus élevée enregistrée officiellement au Royaume-Uni.

"Les températures officielles ont atteint hier à Cambridge une température record de 38,1 ° C, établissant un nouveau record actuel pour la température la plus élevée de juillet."

La nouvelle nous parvient alors que les passagers à Heathrow ont été laissés endormis sur le sol sur des tapis de style yoga alors qu'ils continuaient à subir le chaos de voyage causé par le temps.

Et les perspectives de voyage restent sombres aujourd'hui – avec les répercussions des retards et des annulations sur les vols à destination et en provenance de Heathrow et de Gatwick pour le reste de la journée – tandis que certains passagers sont bloqués dans les avions depuis 10 heures.

Et les tempêtes vont se poursuivre ce week-end avec des parties de Londres déjà secouées par les averses de ce matin et six pouces de pluie qui vont tomber dans le nord-est demain, entraînant un risque d'inondation.

Plus de 30 vols ont été supprimés à Heathrow depuis la nuit dernière, 19 autres ont été supprimés à Gatwick, d'autres ont été annulés à Luton et Stansted, tandis que les services sont également affectés aux aéroports de Manchester, Liverpool et Bristol.

Des tempêtes généralisées en Europe ont entraîné la mise en place de restrictions de trafic aérien autour du continent, d'une réduction du nombre d'avions autorisés à voler et d'un retard accumulé au sol dans les aéroports britanniques, qui est toujours en cours d'élimination.

Le service normal reprend pour certains aéroports, notamment Luton et Stansted, tandis que le réseau de trains dans le sud et le sud-est est plongé dans le chaos en raison des câbles électriques aériens endommagés par la chaleur.

De grandes foules se sont également rassemblées à Saint Pancras aujourd'hui, où les passagers de l'Eurostar sont confrontés à des retards "indéterminés" sur les trains à destination de Paris en raison d'un câble éclaté.

Les vacanciers sont également confrontés à des retards pouvant aller jusqu’à une heure sur les trains Eurostar à destination de Bruxelles en raison des risques de flambage des rails par temps très chaud en Europe, tandis que le vendredi est également le jour le plus achalandé pour le service, ce qui signifie qu’il ya moins de sièges vides à offrir aux passagers dont les trajets ont été réarrangés.

Des adultes et des enfants ont été photographiés couchés sur des matelas fournis par le personnel d'Heathrow au terminal 5 ce matin pour tenter de se reposer en attendant les détails de leur vol.

Ce matin, d'autres personnes à Heathrow ont été photographiées en train de dormir sur des sièges ou couchées par terre sur des couvertures et des serviettes

Sur la photo, une femme à Heathrow ce matin a montré des signes de tension en se tenant la tête entre ses mains, les passagers attendant plusieurs heures avant de savoir quand et si leur vol partirait.

Des passagers en colère ont critiqué le personnel des compagnies aériennes et des aéroports sur les médias sociaux, un utilisateur des médias sociaux reprochant à Heathrow d'avoir gardé sa sœur dans l'avion pendant une nuit, alors qu'un autre a déclaré qu'ils étaient assis dans l'avion pendant deux heures à Heathrow ce matin en raison d'une 'manque de personnel au sol'

Pendant ce temps, un "câble explosant" a entraîné la suspension des trains Eurostar reliant Saint-Pancras à Paris. Aujourd'hui, de grandes foules se rassemblent à la gare de Londres.

Les familles ont été vues à St Pancras aujourd'hui avec des valises empilées dans l'attente d'informations sur leur capacité à partir en vacances.

Certains passagers à Heathrow ont reçu des sacs de couchage la nuit dernière dans l'un des hôtels situés près de l'aéroport et ont été photographiés campant en masse sur le sol.

Les files d'attente tournent autour du terminal 5 à Heathrow aujourd'hui, alors que les vacanciers assiégés tentent de s'éloigner pour leurs vacances.

Les panneaux d'information à Heathrow aujourd'hui, montrés sur la photo, montraient que plusieurs vols avaient été annulés au cours de cet après-midi, des problèmes de contrôle du trafic aérien affectant l'aéroport le reste de la journée.

Les températures au Royaume-Uni seront beaucoup plus fraîches aujourd'hui (à gauche) avec des pluies et des nuages ​​durant le week-end (au centre et à droite)

Des horaires d’urgence sont en place, Thameslink ne réalisant que la moitié de ses liaisons et de nombreuses autres lignes s’attendant à des perturbations tout au long de la journée, notamment le Grand Anglia, le Great Northern, l’East Midlands et le Stansted Express.

Un grand nombre de voyageurs ont exprimé leur colère sur les médias sociaux. Un utilisateur de Twitter a déclaré: «Quel embarras absolu pour nos services de transport, ils se sont tous effondrés ce soir. Un peu de chaleur et l'infrastructure de nombreuses lignes de train échouent. '

Le chaos des voyages a commencé hier soir.

Le météorologue du bureau météorologique, Greg Dewhurst, a déclaré que les orages pourraient continuer jusqu'à vendredi, ce qui augmenterait les risques d'interruption du voyage.

Il a déclaré: «Les orages pourraient continuer de façon intermittente tout au long de la journée. Il y a assez d'énergie dans l'atmosphère pour la maintenir.

Les températures vont du milieu de la vingtaine au plus bas vendredi, a ajouté M. Dewhurst.

Dans une déclaration concernant l'accident système survenu au centre de contrôle de la circulation aérienne de Swanwick, Nats a déclaré: «Nous avons un problème technique avec un système situé au contrôle de la circulation aérienne de Swanwick qui entraîne certaines restrictions de vol.

"Nous faisons tout ce qui est en notre pouvoir pour régler le problème le plus rapidement possible."

Le partenaire européen des Nats, Eurocontrol, a déclaré que les problèmes d'équipement posaient des problèmes à Heathrow et à Gatwick.

Il a ajouté que les retards ont été réduits "mais restent élevés".

Nats était incapable de dire si les problèmes étaient liés à la météo.

Des problèmes techniques affectent également les systèmes de contrôle du trafic aérien à travers l'Europe continentale.

L'agence européenne de coordination du trafic aérien, Eurocontrol, a déclaré que le problème était dû à un "problème d'affichage radar" et qu'il y aurait des délais "élevés" pour les vols à destination de Heathrow et Gatwick pour le reste de la journée.

Les compagnies aériennes ont présenté leurs excuses aux passagers et certaines offrent des chambres d'hôtel, des bons de restauration ou des remboursements.

Les problèmes de contrôle du trafic aérien signifient qu'une limite a été imposée aux vols pouvant être dans le ciel en même temps et aggravera le retard accumulé du fait que les avions restent immobilisés au sol. Il survient après que la tempête ait mis en danger les avions en raison de la foudre et de la turbulence accrue.

Un utilisateur de réseau social a révélé que sa sœur avait été bloquée dans un avion et avait sablé Heathrow, ajoutant: «Ma sœur avec ses petits enfants est restée coincée dans un avion pendant 10 heures et il n'a jamais décollé. Ils n’ont pas laissé sortir les passagers, je suis sûr qu’ils voulaient éviter la foule. Mais 10 heures dans un avion au repos est une frustration de niveau 3. Bravo Heathrow.

Un porte-parole d'Easyjet a déclaré: 'En raison des conditions météorologiques défavorables hier soir, easyJet, comme d'autres compagnies aériennes, a subi des perturbations dans son programme de vols à Londres Gatwick, Londres Stansted, Londres Luton, Liverpool, Manchester et Bristol.

«Nous mettons tout en œuvre pour minimiser l'impact de la perturbation sur nos clients et pour organiser des déplacements alternatifs. Les clients des vols annulés ont la possibilité de transférer leur vol gratuitement ou de recevoir un remboursement. Nous avons également fourni des chambres d'hôtel et des repas aux clients qui en ont fait la demande. Tous les clients qui se sont arrangés pour la leur seront remboursés pour des frais raisonnables.

«La sécurité et le bien-être de nos clients et de notre équipe sont notre priorité absolue.

"Bien que cela échappe à notre contrôle, nous aimerions nous excuser pour tout inconvénient occasionné par le mauvais temps."

Un porte-parole de British Airways a ajouté: «Comme toutes les compagnies aériennes, nous avons été affectés par des conditions météorologiques défavorables jusqu'au lendemain et aujourd'hui, ainsi qu'un problème technique lié au contrôle de la circulation aérienne réduisant le nombre d'arrivées dans les aéroports de Heathrow et Gatwick.

«Nous faisons tout ce qui est en notre pouvoir pour minimiser les perturbations et nos équipes travaillent sans relâche pour que le plus grand nombre possible de nos clients puissent partir en voyage.

«Nous nous sommes excusés auprès de nos clients et nous les avons réenregistrés sur des services alternatifs ou leur avons proposé un hébergement à l'hôtel si nécessaire. Un séjour sans faille

"Nous conseillons aux clients de consulter ba.com pour obtenir les dernières informations sur les vols avant de se rendre à l'aéroport."

De nombreux passagers des médias sociaux ont été scandalisés par le "manque de préparation" à la météo et ont qualifié leur traitement de "dégoûtants" après avoir été maintenus dans l'avion ou bloqués à l'aéroport.

Les passagers bloqués dans les aéroports ont également critiqué les responsables pour leur manque d'informations et pour ne pas avoir aidé les voyageurs à se sentir mal à l'aise.

L’hôtel Sofitel à Heathrow a même distribué des sacs de couchage avec une zone du sol de l’aéroport rendue «disponible» pour les passagers laissés dans l’incertitude afin de les faire camper pour la nuit.

Simon Dix, professeur de sciences politiques, a écrit sur Twitter: «Nous sommes bloqués à Heathrow depuis 16 heures! British Airways a été absolument épouvantable. Aucune aide que ce soit. Nous nous sommes assis dans l'avion pendant 5 heures avec très peu d'informations.

"Ils nous ont ensuite fait descendre de l'avion et ne nous ont donné aucune information sur les réservations, les bagages ou quoi que ce soit."

Il a ajouté: "Je ne ferai plus jamais cette compagnie aérienne de mauvaise qualité, et j'annule mon abonnement BA (Silver)".

Une mère, qui a demandé à ne pas être nommée, a raconté que ses quatre enfants avaient été enlevés d’un vol Tui annulé et qu’il leur restait à essayer de dormir sur un sol "poussiéreux" à Gatwick. Les blanchisseurs n’avaient offert que des couvertures à 3 heures du matin. personnel de l'aéroport.

Pendant ce temps, les passagers ont également parlé de leurs épreuves sur les médias sociaux. Un utilisateur de Twitter a écrit: «Deux heures et deux heures passées dans l'avion en raison du manque de personnel au sol au T5 Heathrow. Disgrâce absolue.

Un autre a déclaré: «Dernière expérience incroyable avec @HeathrowAirport: atterri il y a une heure et demie mais aucune porte n'est disponible.

«Nous sommes coincés dans l'avion et notre capitaine vient de nous dire qu'il ne sait ni où et quand nous pourrons nous garer. vol de correspondance perdu. L’aéroport est en plein chaos.

Sur la photo, les services Eurostar à Saint-Pancras ont également été affectés car les vendredis sont le jour le plus achalandé de la semaine pour le service, ce qui signifie qu'il y a moins de places gratuites dans les trains à offrir aux passagers dont les trajets sont réarrangés.

Le chaos lié aux voyages s'étend également aux routes, avec un trafic bloqué dans le tunnel de Dartford sur la M25, sur la photo, où les vacanciers tentent de s'éloigner pour une pause.

Les vacanciers à St Pancras, sur la photo, grouillent de jour en jour autour des officiels alors qu'ils essayaient de savoir combien de temps ils resteraient dans l'attente des trains

Les vacanciers sont toujours confrontés à des retards à Heathrow ce matin (photos), avec des vols retardés et annulés jusque dans l'après-midi, y compris des voyages à Edimbourg, Rome, Berlin, Genève et aussi loin que Boston.

Les retards et les annulations de vols se sont encore aggravés aujourd'hui, après que NATS eut révélé des problèmes techniques au centre de contrôle de la circulation aérienne de Swanwick.

Des enfants dormaient également sur le sol à l'aéroport de Luton, ce matin, alors que les familles attendaient pour partir en vacances d'été

Les files d'attente aux guichets d'enregistrement de British Airway étaient encore nombreuses ce matin, comme l'illustre la photo, alors que la compagnie aérienne s'efforçait de résorber un arriéré de vols accumulés la nuit après les annulations liées aux conditions météorologiques.

Les touristes se rendant à l'étranger à bord de l'Eurostar grouillent autour de St Pancras aujourd'hui, photographiés alors qu'ils se battaient pour prendre leurs trains.

Un utilisateur de Twitter indigné a ajouté: Lorsqu'il pleut, les trains s'arrêtent. Quand il neige, même un flocon, les trains s'arrêtent. Lorsque le vent souffle une feuille sur la voie, les trains s'arrêtent.

«Et maintenant, il semble que, dans une vague de chaleur, les trains s'arrêtent. London Transport, supposons qu'il se produira des conditions météorologiques favorables. Prepare for SOMETHING please!'

Another said: 'Hot weather in England: there are no rules. There are no laws. There are no other topics of conversation.

'Boats explode, people walk the streets entirely nude, there is a national shortage of icecream, public transport ceases to run.'

Passenger Craig Beale also blasted Heathrow after sharing a video of a crowd of around 1,000 people waiting for taxis at the airport to take them home or to hotels to wait for more information.

He wrote on Twitter: '@HeathrowAirport, you are a joke! No staff on hand to help thousands of stranded customers.

'All bags not returned to customers. A queue of over 1,000 people for taxi's. How can you leave people like this?!'

Rare lightning strike on a lunar rainbow

The rare but stunning stunning moment a bolt of lightning struck across a lunar rainbow has been caught on camera. Voir l’article : Comment prendre soin des animaux domestiques par temps chaud.

The photo was taken on Mersea Island, near Clacton-on-Sea, Essex, as a dramatic electrical storm erupted over the sandy beach early on Friday morning.

It was snapped by amateur photographer Shaun Mills, 49, who was so pleased with the shot that he did a 'little jig' on the beach afterwards.

Stunning moment a bolt of lightning shot down over a lunar rainbow on a picturesque Mersea Island beach in Essex

Lunar rainbows, more commonly known as 'moonbows', are produced by light that is reflected from the moon rather than directly from the sun.

They are much fainter than solar rainbows, due to the smaller amount of light reflected from the surface of the moon.

As such the human eye often struggles to discern the colours.

The weather phenomenon occurred at around 8pm last night (Thurs).

Mr Mills, a banker by profession, said: 'I could see the clouds building up and heard some really nice elongated rumbles of thunder.

'I only live a few minutes from the beach so I just headed over there to see what I could get.

'When I saw the photo of the lightning with the rainbow in it too I must be honest I did a little jig on the beach.

'I'm really pleased with the picture and it was a real spectacle.'

She said there are no further flights or trains available to Brussels today and faces another night of waiting following her business trip, adding she has not heard from the airline regarding compensation.

A Heathrow spokesperson said: 'We apologise for the disruption caused by extreme weather conditions across Europe last night and are working alongside our airline partners to keep passengers travelling.

'We advise those due to travel to contact their airline for up to date flight information.

A spokesman for Gatwick said last night: 'A number of flights have been impacted this evening due to weather conditions across UK and Europe with subsequent airspace restrictions, and we apologise to anyone affected by this disruption.

'Passengers should contact their airline for the latest information about their flight.'

A spokesman for Luton Airport said said: 'Thunderstorms across Europe, tracking towards South East of England have resulted in air traffic control restrictions this evening, causing a number of delays and cancellations at all London airports.'

It follows a day of travel chaos for commuters up and down the country with hundreds stranded on sweltering services while they struggled to get home from work yesterday.

Meanwhile the stormy weather is continuing to batter Britain today, leading to flood warnings. Pictured are pedestrians trying to stay dry in Wanstead, London this morning

The rains have brought an end to the extreme heat but are only causing more problems. Pictured are people ducking for cover under a bus shelter in Wanstead this morning

Fed-up Brits have vented their fury on social media today about the 'lack of preparation' for extreme weather and the travel chaos that has followed. Some passengers revealed they were stuck on planes with no connecting flights and no idea when they would be able to get to a gate

Others said there are 'no rules' in Britain when hot weather strikes while some labelled UK transport services an 'embarrassment'

Sparks from overheated cables caused a trackside fire last night while police hauled trapped passengers off a sweltering train in two separate incidents.

Overhead lines can also expand and sag in extreme heat, bringing a risk of passing trains pulling them down.

Rail companies are working to repair damage caused by the extreme heat but say the disruption is due to continue today.

Many train lines suffered structural damage in the heat with overhead lines damaged.

A speed limit was in place across the network yesterday to stop tracks buckling – leading to further delays.

Network Rail have advised passengers to check with their train operator before travelling.

Flights have been delayed across the country due to thunderstorms across Europe leaving passengers furious. Pictured is the scene at Heathrow yesterday with passengers queuing around the terminal to find out if they can still travel

One mother, who asked not to be named, said her children, pictured last night, were left trying to sleep on the floor at Gatwick and were only offered blankets by cleaning staff at 3am, rather than by officials

One social media user stuck at Heathrow uploaded a picture of a brass band keeping travellers entertained last night, and tweeted: 'Flight stranded, 3,5h (sic) and still no update on departure. We do have a whole Balkan band onboard tho :)'

Lengthy queues in sweltering conditions at Stansted Airport yesterday were caused when thunderstorms delayed or grounded flights

Cancelled: Late yesterday evening flights inbound to Stansted from Central and Eastern Europe were cancelled in the heat

Many passengers took to social media to complain that little or no information was being imparted over tannoy systems. Pictured are crowds at Stansted Airport yesterday

Some operators have offered passengers tickets for Saturday and Sunday if they are unable to travel today.

Engineers worked overnight to repair damage at several locations after the temperature of steel tracks soared to up to 20C higher than the air temperature, while overhead power lines also suffered heat-related damage.

Apologising to commuters for delays and cancellations, Phil James, from Network Rail, said: 'I want to say sorry to passengers for the disruption and discomfort they faced making their journeys yesterday.

'The extreme temperatures made travelling by train very difficult at times and we thank passengers for their patience while we worked hard to get people moving again.

'With the railway being made of metal and moving parts, the sustained high temperatures took their toll in places.

'Everything was done to keep trains moving where possible, and last night hundreds of staff were out fixing the damage and repairing the railway ready for today.'

A rare sighting of a 'Supercell' stormcloud

Over Slaley, Northumberland, a rare sighting of a 'Supercell' stormcloud could be seen dominating the skyline last night. Lire aussi : La Terre a-t-elle déjà été aussi chaude?.

Characterised by the presence of a mesocyclone – a deep, persistently rotating updraft – supercells are often referred to as rotating thunderstorms and are more commonly seen in the Great Plains of the USA.

Supercells are the least common type of thunderstorm and are often associated with severe weather, including violent tornadoes.

Airport chaos was put down to lightning storms across Europe which caused air traffic restrictions. Pictured is lightning hitting Blackpool tower yesterday evening

Storms continued to rage throughout the night, leading to knock-on cancellations this morning. Pictured is a storm in Aylesford, Kent, overnight

Network Rail said in a statement: 'Yesterday saw significant disruption on the rail route which links Sheffield to London St Pancras International via the East Midlands and Bedfordshire.

'Trains had to run at reduced speeds, which also meant a reduced service ran and those which did run were extremely busy.'

Train speeds are being reduced to cut the likelihood of steel tracks buckling after multiple incidents on the network, including problems with overhead equipment on the line between Kentish Town and West Hampstead and a fire near the railway in West Hampstead.

Network Rail added: 'Passengers are strongly advised to consider alternative travel arrangements and only travel if their journey is absolutely necessary.

'If passengers must travel, they are urged to check before travelling with their train operator or with National Rail Enquiries. Passengers should allow additional time for their journey and take plenty of water with them.'

West Midlands Railway said overnight work to repair damage was still ongoing and many trains were starting the day out of place, resulting in some cancellations and shorter trains.

Social media users said the storms around the UK were among the strongest they had ever seen. Pictured is lightning striking the ground in Norwich

Euston station was packed with people as trains struggled in the heat with some tracks buckling and speed limits down

But Govia Thameslink caused more outrage after refusing to pay compensation to season ticket holders who followed its prior advice not to travel because of the scorching temperatures.

The firm, which operates trains in south-east England, said passengers with an annual pass are only entitled to a payout if they attempted a journey on Thursday and were delayed.

This is despite its four train brands – Southern, Thameslink, Great Northern and Gatwick Express – all urging passengers to 'avoid travelling wherever possible'.

Anthony Smith, chief executive of independent watchdog Transport Focus, said: 'All passengers told not to travel due to extreme weather should be entitled to claim compensation.

'Train operators should take the heat out of the situation and do the right thing by reimbursing passengers who have acted on their advice and made alternative plans.

'When things go wrong train operators must ensure every eligible passenger knows about compensation and how to claim.

'To make their voice heard passengers must claim every time and make delay pay.'

A spokesman for GTR, which has repeatedly faced calls to be stripped of its franchise over a series of failures in recent years, told PA: 'A season ticket holder who decided not to travel would not be entitled to any refund or compensation.

'They would have had to make a journey and been delayed.'

Southeastern and GTR have the same parent company, Govia, but the former was one of several operators offering compensation to season ticket holders who did not travel on Thursday.

Rail regulator the Office of Rail and Road said it is examining the National Rail Conditions of Travel to consider whether firms such as GTR should offer compensation to season ticket holders when they advise passengers not to travel.

Meanwhile a deluge of rain is expected to follow the hot weather this weekend.

Met Office meteorologist Alex Burkill said: 'A decaying cold front coming in at the end of the week will bring fresher conditions behind, although it will be warmer ahead of this, across eastern parts of the country.

'On Saturday there will be some heavy and potentially thundery showers in the northeast, the heaviest rain will be over the hills.

'It is likely to be warmer, sunnier and drier in the far north-east of Scotland, elsewhere it will be cooler under the rain although we could see temperatures in the mid-20Cs.

'There will be further heavy rain on Sunday with perhaps the odd thunderstorm in the afternoon and while temperatures will be suppressed where it rains it will be quite warm in places.

'It will remain unsettled next week with more usual weather conditions for the time of year, there will be rain and brisk winds from Monday to Tuesday.

'Beyond the start of the week it should be mostly fine with some scattered showers.'

The Met Office has issued a warning for up to six inches of rain across north-eastern England tomorrow and Sunday.

Met Office chief meteorologist Steve Willington warned to prepare for travel mayhem and the risk of flooding to homes and businesses.

He said: 'There is a small chance that homes and businesses could be flooded, causing damage to some buildings and a small chance of fast-flowing or deep floodwater.

'Where flooding occurs, there is a slight chance of delays or cancellations to train and bus services while spray and flooding could lead to difficult driving conditions and some road closures.'

Meanwhile a Grade-II listed bell tower at an old fire station in Wimbledon went up in flames after being struck by lightning during the heatwave yesterday.

Twenty firefighters were called to the former fire station in Wimbledon and photos show flames rising and smoke billowing from the landmark, before cherry pickers were used to survey the damage.

The strike happened at around 6pm.

Barry Daly, 32, witnessed the aftermath of the lightning strike while walking his dog at 8.30pm.

The property manager, who lives a short walk away, said: 'I was surprised to see the fire brigade and the blue flashing lights as I approached. The fire was out at that stage but people were saying it had been struck by lightning.

'Firefighters were checking things over with cherry pickers. It's a five minute walk from where I live so I pass by the clock often. It's not something you see every day.'

Video from the scene showed around a dozen firefighters with four fire engines assessing the Grade-II listed clock.

Hundreds of commuters were stuck on two trains yesterday after damaged overhead electrical cables caused a grass fire on a railway embankment at Finchley Road station in Hampstead, North London.

Up to 600 passengers were trapped as the blaze took hold, buckling rails and causing chaos for commuters struggling to get home.

Meanwhile, near Peterborough, rescue teams were pictured freeing trapped passengers – including a pregnant woman – who were stranded for two hours without air conditioning. London North Eastern Rail cancelled all services in and out of Kings Cross following the incident.

It follows last night's disruption of Britain's busiest station after man was seen chasing a dog along electrified tracks.

All lines in and out of London Waterloo were blocked at about 7pm due to trespass, South Western Railway said.

Vidéo shared on social media showed a man running along the tracks at the approach to the station.

'We saw a dog running down the track and then, 20 seconds later, a man running after it,' said passenger Adam Willmott, 23. 'The dog was much faster and the man was looking rather tired.'

He said his London-bound train had been stationary for more than 20 minutes with no power. 'We have no air conditioning and it is just getting hotter and hotter,' he said. 'The train manager said he doesn't know when we will move.'

A spokesman for South Western Railway said: 'I can confirm that the trespass incident involves an individual chasing a dog down the rail lines and that services have been held between Waterloo and Vauxhall stations. The British Transport Police have been called to handle the incident.'

It follows earlier disruption at London Euston and London St Pancras because of heat-related problems on tracks. Commuters are stripping to the waist on the London Underground and other services as they face arduous journeys home in baking heat.

Commuters were stuck at St Pancras railway station after overhead cables were damaged, severely disrupting East Midlands and Thameslink services.

Boards displayed at the station announced most trains had been cancelled with others delayed. Two rail workers said the wires had been damaged by fire.

Gary Freeman, 56, a senior worker in the construction industry, faced an unknown delay for his train back to St Neots, Cambridgeshire.

Wiping his forehead repeatedly with a handkerchief, he said: 'This week it's been crazy, last Friday this happened as well. On the hottest day of the year it adds insult to injury.

'I'm debating whether to keep standing here sweating or to go and get a nice cold beer. There are people sitting in trains not moving on the tracks apparently.'

Network Rail's network services director Nick King said: 'We have a number of heat-related incidents across the rail network this evening that are causing disruption to services. We are sorry that some passengers are experiencing uncomfortable conditions and inconvenience.

'Our teams are working flat-out to fix the issues as quickly as possible and get people on the move. We're asking anyone travelling this evening to check with their train operators or visit the National Rail Enquiries website to see how their journey is affected.'

Further travel disruption could be caused by thundery downpours prompted by the sweltering temperatures, with flash flooding and even power cuts possible.

Fears were also raised that patients and staff will face 'totally unbearable' conditions in hospitals as Britain swelters in record-breaking temperatures.

Public health expert Dr Nick Scriven warned of struggles to keep patients and those working hydrated during the summer, with staff being 'so busy they cannot leave wards to find cold drinks'.

Writing for the BMJ, the president of the Society for Acute Medicine said that tired and overheated staff will be prevented from 'giving their best'.

He wrote: 'We are now seeing temperatures even higher than in 2018, but hopefully lasting for a shorter period of time.

'However, the abilities of the NHS to protect both vulnerable patients and its own staff has remained unchanged.

'It is fair to say that the ward environments in many places will be totally unbearable this week, causing distress and concern for all those in them whether working, visiting or as patients.

'This follows reports which suggest that activity has peaked at levels previously not seen in summer.'

During the four heatwaves last summer Public Health England estimated there were up to 863 extra deaths.

A Commons select committee report last year found that NHS England's emergency preparedness, resilience and response assurance 'does not account for the risk of overheating hospitals'.

The report said the impact of heatwaves on nursing homes is also not assessed.

It recommended that NHS bodies submit annual heatwave plans to ensure they are prepared for sudden spells of hot weather.

Dr Scriven added: 'Tired and overheated staff are not capable of giving the best that their patients deserve and it is really time that hospitals and those running them took notice of environmental factors on top of all the existing stresses and strains.

'The NHS needs to take up the challenges posed by the select committee last year as the predictions are that this is only going to become more extreme every year.'

Last night a fire broke out near the tracks of the London to Luton main line after the soaring temperatures reportedly caused cables to overheat.

A rambler collapsed in the heat in Dorset, surfaces melted in Grimsby and Londoners faced searing heat on the Tube with the high humidity expected to make temperatures feel like 109F (43C) in the South East this afternoon.

Temperatures hit 100.6F (38.1C) in Cambridge at 3.30pm – making it the warmest July day on record and the second hottest day in UK history behind the 101.3F (38.5C) in August 2003.

East Midlands Trains urged passengers 'do not travel', while Thameslink said 'you are strongly advised not to travel', after the heat caused damage to overhead electric wires between London St Pancras and Luton. In Greater Manchester, firefighters hosed down Barton swing bridge in Salford to avoid it buckling in the heat.

Hundreds of thousands of commuters who use Southeastern, Greater Anglia, Southern, Gatwick Express, London North Eastern, West Midlands and Great Northern trains also faced delays, cancellations and overcrowding.

Police were called after scuffles broke out at the Brockwell and Parliament Hill lidos in London as hundreds of people tried to get in, while food was removed from the shelves of a Sainsbury's in Bolton after its fridges broke.

As hundreds of thousands of people sunbathed in beaches and parks, fan sales rose 200 per cent at some stores and bosses at Madame Tussauds Blackpool had to move waxworks out of direct sunlight to avoid them melting.

Police warned people over swimming in the heatwave after three men drowned and another was reported missing, while racing at Southwell was abandoned with two races remaining due to the 'extreme temperatures'.

The heat was all too much for some men, who took off their shirts as they rode public transport. One shirtless man was seen working on his laptop on an air-conditioned train from London King's Cross to Ely in Cambridgeshire.

The heat also affected mainland Europe, with Paris recording its hottest day ever as temperatures topped 109F (42.6C) – smashing a 70-year-old record – while Germany, Belgium and the Netherlands also set all-time records.

Forecasters warned that flooding and lightning strikes could affect driving conditions, disrupt train services and lead to power cuts, although temperatures are expected to become much cooler from tomorrow onwards.

There is then a further warning for heavy rain in northern England and southern Scotland from 12pm Saturday until 3pm Sunday, with up to 4.7in (120mm) expected over the Pennines and North York Moors plus a flooding risk.

Police had to be called to an outdoor swimming pool after hordes of overheating Londoners tried to force their way in. Around 500 people tried to storm Brockwell Lido in South East London during the heat.

Tempers flared around midday when waiting times topped three hours. The Metropolitan Police said: 'Police were called to Brockwell Lido to reports of overcrowding.

'Officers attended. Security staff at the lido have closed the doors as a group of 500 people are trying to get in. The owners of the venue are advising people not to come as there is a three-hour waiting time.'

Gauri Kangai posted a picture of the fracas on Twitter with the words 'No City for Keeping Cool'. She added: 'Raises (questions) about design in cities for extreme climate instances like today.'

There were similar scenes elsewhere in the capital – with Parliament Hill Lido forced to refuse further entry just before noon due to overcrowding.

Police were repeatedly forced to attend the pool after fights broke out in the queue, and eventually the Met decided to leave an officer effectively on guard to prevent any more disruption.

The force said: 'Officers were first called to the venue at 9.49am when a number of minor scuffles broke out as swimmers queued to enter the lido. Further incidents of disorder broke out throughout the day.'

A spokesman said there had been no arrests or any reported injuries, but added: 'Police remain in attendance to prevent a breach of the peace.'

In Bristol, Portishead Lido warned those hoping to cool off of long queues. Staff tweeted: 'Be prepared for a long wait, and there's no shade. Bring water, snacks, folding chairs, sunscreen, a hat and some patience and humour.'

Lidos in Peterborough, London's Tooting Bec and at Hemsley in York were also forced to turn away disappointed swimmers after reaching capacity.

In Bristol, a burst water main left hundreds of homes in the Speedwell, Eastville, Fishponds and Horfield areas without water, with engineers saying they are working 'as quickly as possible' to restore the supply.

A Bristol Water spokesman said: 'With the weather being as hot as it has been we get ground movements. It's very likely ground movements has caused friction to increase and decrease the pipe size and unfortunately it's burst.'

It comes as the Environment Agency said spy drones will be used for the first time this summer to catch cheating farmers who are taking out too much water from rivers to pit on their parched crops.

Some people used electric fans to cope with the heat, with sales at Currys PC World up 200 per cent and John Lewis reporting selling six every minute.

And Aldi sold out of its 12ft garden swimming pool just 10 days after it went on sale for £89.99. The circular 'Intex Metal Frame Pool' can hold 7,199 litres of water but it was no longer available to buy on its website.

The budget store is also selling giant inflatable flamingo pool floats for £19.99 and a water slide for £12.99.

Bosses at Madame Tussauds Blackpool said they had moved waxwork figures of Ariana Grande and Freddie Mercury out of direct sunlight and away from windows to keep them cool in the intense heat.

A swimmer drowned yesterday while taking a cooling dip in the sea.

Paramedics and police were called to Norman's Bay in Pevensey, East Sussex, shortly before lunchtrime after a body was spotted floating in the water just off the beach.

Rescuers who rushed to the scene managed to pull the victim onto the beach and attempted heart massage but the person was certified dead at the scene.

The body was taken by ambulance to the mortuary at the Conquest Hospital in nearby Hastings where a post mortem examination will be carried out to ascertain the exact cause of death.

Parts of the London Overground were suspended due to heat-related speed restrictions, while a points failure near Potters Bar and a signalling fault near East Croydon caused further disruption for commuters this morning.

London Northwestern Railway and West Midlands Railway advised passengers not to start new journeys as high temperatures are disrupting its services to London and across the West Midlands.

A spokesman for the operators said: 'We are sorry to have to issue this advice. We don't make these decisions very often nor do we take them lightly.

'Faced with multiple heat related incidents across our network the responsible thing is to focus on people already travelling. We will be doing all we can to get people home this evening.'

The scorching temperatures caused damage to overhead electric wires between London St Pancras and Luton, blocking all lines. This is affecting East Midlands Trains and Thameslink services.

Motoring organisations warned the scorching heat could cause roads to 'melt like chocolate', requiring gritters to be called out.

Commuters on the Central and Bakerloo lines of the London Underground sweltered in temperatures of at least 89.1F (31.7C), saying they 'are being treated like animals'.

NHS worker Jimmy Lyons, 38, of north London, was travelling into work on the Central Line this morning.

He said: 'There's still no proper air conditioning in this day and age and I want money invested.

'I've just got back from America – if there was no proper air con they would sue.

'Animals aren't even transported in this heat.'

Annie Parker, 45, a British expat data analyst in Oman who regularly works in London, said she missed the trains in the Middle Eastern country.

Pavement MELTS under pedestrian's feet

Temperatures have been soaring so much in parts of Britain that the heat is now melting roads.

Rick Byrne filmed the pavement melting underneath his feet in Grimsby, Lincolnshire, and after just a few seconds it showed the imprint of his trainers.

Shoe prints can be seen in the road in Grimsby yesterday

The road surface was starting to come loose yesterday as temperatures hit 84F (29C) with ridges and lines appearing from passing cars.

And video footage showed shoe prints appearing in the road after just a few seconds of standing in one spot.

Previously in hot weather, councils have sent gritters to try to stop melting roads causing problems for drivers.

Travelling on the Central line in shorts and a tank top, she said: 'Yesterday on the Jubilee line was horrendous. London is one of the biggest cities in the world and we've had the Tube here for a long, long time but there's never been any investment.

'We are just not considered high enough priority. In Oman it's worse outside but it's better inside. There's air con everywhere and the Tubes there aren't only AC but there's refreshing smells as well.

'That's how they combat body odour and it makes it more pleasant and everyone's clean – you don't appreciate until you don't have it.'

Trainee lawyer Emma Holder, 25, pays £7 a day to commute from Finsbury Park in North London.

She said: 'It's the worst part of my day for sure. I think we've being treated like animals – everyday one of my friends will say on our WhatsApp chat that it's ridiculous.

'It's hot and it's not acceptable because it's really expensive to get the Tube and when you're paying a certain amount you expect it to be a decent service. I don't understand why other cities that have the Tube have a decent service.'

Business Paul Fletcher, 67, from Holland Park, said: 'I think we are being treated like animals. I use the Central line most days – that really is a properly terrible service. I think they are a nightmare. They've got to make investment and air conditioning.'

It follows dramatic thunderstorms which battered large areas of the UK on Tuesday night, with spectacular images showing lightning illuminating the night sky. There were said to have been about 48,000 lightning strikes.

Several buildings were damaged and hundreds of homes in Norfolk were left without power.

The Met Office has issued a warning for further thunderstorms tonight, covering the east of the country from 3pm lasting into tomorrow morning.

It forecast temperatures of 37C (98F) but said there is a 70 per cent chance the UK record of 38.5C (101F) will be broken.

That was set in Kent during the heatwave of August 2003 in which more than 2,000 people died.

Met Office meteorologist Greg Dewhurst said:'It will get into the 30s across the country and reach the mid-30s in the South East.

'If it is to get to 39C, it will happen somewhere between London and Cambridge. Temperatures locally could also break July or all-time records.'

Health professionals warned that the elderly and those with heart and respiratory problems are again at risk. Hospitals are expected to face extra pressure as cases of dehydration soar.

Councils urged people to check on vulnerable friends and family, while parents are advised to take extra care to keep babies and young children cool.

Pets and zoo animals are also at risk. Monkeys were given ice lollies containing carrots, sweet potato and honey to keep them cool at Longleat Safari Park.

Police issued a warning about swimming during the heatwave after three men drowned and another was reported missing. The first man drowned at Cotswold Water Park in Gloucestershire on Tuesday.

Divers then recovered the body of a 23-year-old from the River Thames at Shadwell Basin and a 47-year-old further along the river at Kingston yesterday, while the search continues for a man last seen in the water at Waterloo Bridge on Tuesday.

The UK was hit by thunderstorms overnight on Tuesday, with a series of images showing lightning illuminating the night sky.

One video caught the moment a bolt of lightning struck a chimney in Bristol, creating a fireball.

Paul Krekelaar was filming out his window around 1am and saw a small explosion over a neighbour's house.

A huge bang could be heard as the lightning struck the chimney and burst into flames.

Roofs were also set alight in Cheshire and Nottingham while stunning images captured the moment lightning struck the 17th century Grade I-listed Chesterton Windmill near Leamington Spa, Warwickshire.

The heatwave has been caused by what is known as an 'omega block', where high-pressure blocks and diverts the jet stream, allowing hot air to flow up from northern Africa. It follows another heatwave in June.

Met Office spokesman Oli Claydon said: 'There's a very large area of high pressure over eastern Europe and up into Scandinavia.

'That's combined with a jet stream that has taken a bit of a downturn to the south across the Atlantic, then shooting up north to the west of the UK.

'That combination of the jet stream and the high pressure is working to funnel up the warm air from the continent which has its source origins in North Africa.'

Hundreds of thousands of commuters who services across the UK faced delays, cancellations and overcrowding

There was a similar scene across much of Europe. The Netherlands and Belgium recorded their highest ever temperatures yesterday of 102F (39.1C) and 102F (38.9C).

Southeastern, which operates trains in Kent and parts of East Sussex, said it would be running a 'significantly reduced service' due to speed restrictions imposed by Network Rail amid fears tracks are at risk of buckling.

Extreme weather action teams (EWATs) have been 'activated' to keep passengers safe and trains running, Network Rail said.

The Rail Delivery Group, which represents the industry, advised passengers in London and the South East to consider changing their travel plans on Thursday owing to the heat.

London North Eastern Railway, which runs inter-city services on the East Coast Main Line, advised customers against travelling.

Those making long car journeys cannot rely on the radio for company – FM and AM radio signals can be disrupted in hot weather because signals from local stations can travel further and cause interference outside their usual range.

The Met Office has warned heatwaves are on the increase as a result of climate change.

Conditions will be much cooler today as the very hot weather ends, with rain showers also possible for many parts

It is even possible the mercury could climb to 104F (40C), which would be 'unprecedented' for the UK climate, weather forecasters said.

How to keep cool: Heat advice as rambler is rescued from coast path

England's chief nurse has urged people to check on their neighbours as a heatwave hits parts of the UK for the start of the school summer holidays.

It comes as a rambler succumbed to the heat and had to be rescued from a coast path.

Graham Glynn, 73, collapsed with heatstroke while walking on the South West Coast Path near Weymouth, Dorset, in temperatures of 81F (27C).

Coastguards and ambulance paramedics treated him at the scene before he was stretchered off the path, over a stile, through a cow field and into a waiting ambulance.

Public Health England (PHE) is urging people to stay cool as temperatures soar and has reminded them not to leave children or animals in parked cars.

Owen Landeg, principal environmental public health scientist at PHE, said: 'Much of the advice on beating the heat is common sense and for many people spells of warmer weather are something they very much enjoy.

'However, for some people, such as older people, those with underlying health conditions and young children, the summer heat can bring real health risks. That's why we're urging everyone to keep an eye on those you know who may be at risk this summer.

Mr Glynn, 73, collapsed with heatstroke while walking along the South West Coast Path near Weymouth yesterday

'If you're able, ask if your friends, family or neighbours need any support. Also take water with you when travelling and keep up to date with weather forecasts.

'It's also worth remembering to think about practical steps to keep homes cool during the day as this can aid sleeping at night and give the body time to recover from the heat.'

Public Health England warns that the main risks posed by a heatwave are:

• not having enough water (dehydration)
• overheating, which can make symptoms worse for people who already have problems with their heart or breathing
• heat exhaustion and heatstroke

The Met Office has raised a Level 2 heatwave alert for this week. Public Health England advises people to stay tuned to the weather forecast, check the forecast at their destination if travelling, and keep cool at home. Tips for coping include:

• Shut windows and pull down the shades when it's hotter outside. You can open the windows for ventilation when it's cooler.
• Avoid the heat: stay out of the sun and do not go out between 11am and 3pm (the hottest part of the day) if you're vulnerable to the effects of heat.
• Keep rooms cool by using shades or reflective material outside the windows. If this is not possible, use light-coloured curtains and keep them closed (metallic blinds and dark curtains can make the room hotter).
• Have cool baths or showers, and splash yourself with cool water.
• Drink plenty of fluids and avoid excess alcohol. Water, lower fat milks and tea and coffee are good options. You can also drink fruit juice, smoothies and soft drinks, but they can be high in sugar.

The scorching temperatures gripping the UK and much of Europe come against a backdrop of global warming of 1C since the Industrial Revolution driven by greenhouse gas emissions, forecasters added.

Professor Peter Stott, from the Met Office, said: 'There's no doubt that climate change is playing a role here because of the elevated temperatures and that's related to the fact we've got this weather pattern being drawn up from North Africa.'

That part of the world has warmed by double the global average, while continental areas are warming faster than over the sea.

So when the UK shares weather patterns with places that are warming fast, it is 'pushing us into temperatures that are unprecedented, pushing us into those ranges that we have never seen before or are very, very infrequent', he said.

He added that the existing record temperature for the UK, of 38.5C, set in August 2003 in Faversham, Kent, was set in recent times when the impact of climate change was already being felt.

And it is not just the UK, with heatwaves seen across the northern hemisphere both this summer and last.

The east coast of America has recently been in the grip of a heatwave and much of Europe is seeing records broken at the moment, while last year, Europe and Japan saw sweltering summer conditions.

'Having this frequency of heatwaves across the hemisphere would have been extraordinarily unlikely without climate change, and it's now being made a possibility, and it's what we're seeing,' Professor Stott said.

A study from the Met Office previously showed last year's summer heatwave was made around 30 times more likely than it would be under natural conditions as a result of human activity driving global warming.

Dr Michael Byrne, from Oxford University, said that if Thursday becomes the hottest day on record in the UK it would be 'hugely significant', but just the latest in a 'torrent' of temperature records being broken in the last month.

'Not only has 2019 brought the world its hottest ever June, but in recent days countries from Belgium to the Netherlands to Germany have broken their all-time heat records. It has never been hotter in northern Europe.

'Such extreme heat poses serious health risks this week as well as uncomfortable questions about how well the UK is preparing for increasingly frequent and severe heatwaves over coming decades.'

The Government's advisory Committee on Climate Change has warned the UK is not prepared for the increase in heatwaves that is expected with global warming.

The extreme temperatures are also expected to put pressure on hospitals.

Analysis of admissions due to dehydration found that when temperatures hit 87.8F (31C), admissions rose by 22.7 per cent amongst the general population, and 33.3 per cent for the elderly.

An extra two degrees hotter, and admissions rise by 127 per cent amongst the general population and 150 per cent for the elderly, research by Draper & Dash found.

The weather has led to uncomfortable, restless nights for many, while there has also been a surge in the number of people looking up symptoms of heat-related illnesses on the NHS website.

Dr Nick Scriven, president of the Society for Acute Medicine, said NHS staff were 'struggling' as 'few lessons had been learned' from last year's heatwaves and few hospitals are prepared for the impact of intense heat.

He said 'overheated and exhausted staff' are at greater risk of making errors.

Last year, hospitals hired in large fans and coolers for a week or so but have got nothing long-term in place – they are purely reactive not proactive.

'Some better organisations bought in lots of bottled water and gave it to staff or brought round cooled drinks. To get drinks, staff would usually need to leave the ward to buy them.

'There is often nothing or very little in place for staff to get fluids on wards on an ad-hoc basis and they are expected only to drink in breaks which isn't right when temperature on wards are really high.

'Patient areas don't have coolers or ice machines due to infection concerns.'

The Lullaby Trust, which works to raise awareness of sudden infant death syndrome (SIDS) also known as Cot Death, issued advice for parents to keep their babies safe and cool this summer.

It warned that babies who get too hot are at an increased risk of SIDS and said the ideal temperature of a baby's room should be 61F (16C) to 68F (20C).

As the country sizzled, Labour led calls for workers to be protected from stiflingly hot temperatures, with legal safeguards to help them stay cool.

Under plans revealed by the party, if a workplace reaches 86F (30C), or 80.6F (27C) for those doing strenuous work, employers will have to put in place effective controls.

Current guidance only referring to a minimum working temperature but not an upper limit.

The capital's first purpose-built swimming lake in Beckenham, South East London, was forced to close after just five days after council chiefs were overwhelmed by the numbers who turned up.

Coral said it was odds-on at 1-2 for the UK's hottest ever temperature to be recorded today.

Spokesman John Hill said: 'In what is certain to be sweltering conditions, the odds have been cut on 40C or higher being recorded, while we are being bombarded with bets on this being the hottest summer ever in the UK.'

Meanwhile, the owner of Magnum, Carte d'or and Ben & Jerry's has admitted ice cream sales took a hit in spring and early summer this year due to the cooler weather.

Unilever, which also owns brands including Hellmans and Dove, said the previous two summers had started positively, but this year – particularly in May – the weather had been far too cool.

Chief financial officer Graeme Pitkethly said: 'There were a number of swings and roundabouts. It seems ironic with record temperatures (today) but during the period it was quite negative with strong early summers before.'

What a difference a day makes! The heavens open over Britain… 24 hours after UK roasted on hottest July day in history

By Milly Vincent for MailOnline

From scorching hot temperatures to heavy spells of rain, the UK packs away their bikinis and paddling pools to endure a day of downpours as the tropical humidity breaks and the heavens open.

The heatwave which was triggered by the build-up of high pressures over Europe over the past few days has now cleared with low pressure areas bringing bouts of heavy rain and cooler temperatures of 75 F.

Last night thunder storms could be heard across England as lightning illuminated skies across the country.

Heavy rain is now predicted in much of England for tomorrow with yellow weather warnings in place for Saturday and Sunday, and temperatures expected to fall to 68 F.

The Met Office warns of the likelihood of further delays and cancellations to train and bus services following flooding.

Despite a drop in temperatures today, rail passengers are being urged to avoid unnecessary travel as efforts continue to repair damage to the network caused by the record-breaking temperatures yesterday.

NOT a fan of the heatwave! How desperate Britons are coping with scorching tropical temperatures from taking the Tube in pants and flip-flops to alfresco ironing

Britons struggled to cope with record breaking temperatures as the second hottest day on record saw passengers strip off and spread out as they moaned the stifling conditions.

Scantily clad bodies lined public transport as commuters carried industrial fans with them and cooked eggs on their car dashboards as the UK sweltered in more than 100F (37.7C) heat.

One unfortunate sunbather was bitten by mosquitoes, but was unable to treat his wound when it started melting before his eyes.

WHAT IS CAUSING THE HEATWAVE?

The heatwave has been triggered by the build-up of high pressures over Europe over the past few days, leading to the northward movement of warm air from Europe over the UK.

'At this time of year southerly winds will always lead to above average temperatures,' said University of Reading meteorologist Peter Inness.

'Air from continental Europe, the Mediterranean and even North Africa is brought over the UK.'

'The eastward passage of weather fronts and low pressures from the North Atlantic are currently being blocked by the high pressure over Europe,' added University of Reading climate scientist Len Shaffrey.

Dans les vagues de chaleur, les fans peuvent faire plus de mal que de bien

Par Dennis Thompson HealthDay Reporter MARDI 6 août 2019 (HealthDay News) -…

IS IT RELATED TO THE US HEATWAVE?

The US's recent warm weather has been caused by a high-pressure dome building up over much of the country, trapping the summer heat.

This has wider-reaching effects.

'Heatwave conditions in the U.S Midwest and the East coast have strengthened the jet stream,' explained environmental scientist Kate Sambrook of the University of Leeds.

'The resulting thunderstorms occurring on the continent have helped the jet stream to meander and move to the north of the U.K.'

'As a result of this shift, hot air has been drawn up from Europe causing the high temperatures we are experiencing this week.'

HOW LONG WILL THE HEAT LAST?

'Although there is some uncertainty in the forecast, it looks like it will become cooler on Friday as the high pressure over Europe moves slowly towards the east,' said Dr Shaffrey.

'This will allow weather fronts to move over the UK, bringing cooler air and possibly some rain,' Professor Shaffrey added,

HOW HOT WILL IT GET?

Meteorologists are predicting high temperatures reaching up to 100°F (38°C) over central and Eastern England on Thursday.

Although different forecasts are anticipating slightly different details, 'the broad message of all the forecasts is the same,' said Dr Inness.

'It will be hot, with high temperatures persisting through the night time periods, and there is the risk of some thunderstorms over the UK.'

These will continue through Wednesday.

'If conditions continue, it is likely that we could experience the hottest July on record,' said Dr Sambrook.

'However, the outcome is uncertain as conditions are expected to change early next week.'

University of Oxford climate scientist Karsten Haustein added that 'there is a 40–50 per cent chance that this will be the warmest July on record.'

The final estimate depends on which observational dataset is used, he noted.

While agreeing that the next week's weather will determine this July's place in the record books, Dr Inness noted that 2019 did bring us the warmest June known since the year 1880.

'In fact, 9 of the 10 warmest Junes in the global record have happened since 2000', he said.

In Europe, he noted, this June was also the warmest on record, reaching almost a whole degree Celsius above the previous number one back in 2003.

'Weather records are not normally broken by such large margins — a few tenths of a degree would be more likely.'

The present conditions may turn out to be record-breaking, but they are also part of a recent trend towards warmer UK summers.

'2018 was the joint hottest (year) on record with highest temperature measured at around 35°C, similar to temperatures expected this week,' said University of Leeds climatologist Declan Finney.

The likelihood of experiencing such hot summers has risen from a less than 10 per cent chance in the 1980s to as high as a 25 per chance today, he added.

IS CLIMATE CHANGE CAUSING HEATWAVES?

'The fact that so many recent years have had very high summer temperatures both globally and across Europe is very much in line with what we expect from man-made global warming,' said Dr Inness.

'Changes in the intensity and likelihood of extreme weather is how climate change manifests,' said environmental scientist Friederike Otto of the University of Oxford.

'That doesn't mean every extreme event is more intense because of it, but a lot are. For example, every heatwave occurring in Europe today is made more likely and more intense by human-induced climate change.'

However, local factors also play a role, with each extreme weather event being influenced by the location, season, intensity and duration.

The present heatwave is not the only notable indicator of climate change, experts note, with ongoing droughts — such as those being experienced in many parts of Germany — also being in line with scientific predictions.

Research into the 2003 European heatwave suggested at the time that human activity had more than doubled the risk of such warm summers — and that annual heatwaves like we are experiencing now could become commonplace by around the middle of the century.

'It has been estimated that about 35,000 people died as a result of the European heatwave in 2003, so this is not a trivial issue,' said Dr Inness.

'With further climate change there could be a 50% chance of having hot summers in the future,' agreed Dr Finney.

'That's similar to saying that a normal summer in future will be as hot as our hottest summers to date,' he ad
