Hundreds of schools plan closures ahead of red heat alerts

<p>The UK had been forecast to experience its hottest June day on Tuesday, but temperatures were around 2C or 3C lower than predicted in south-east England after intense rainfall and flash flooding in some locations overnight.</p>

<p>Overnight temperatures will also remain high this week and some locations will not get cooler than 20C, becoming what is known as a tropical night.</p>

<p>A red heat health alert has also been issued by the UK Health Security Agency (UKHSA), from 01:00 on Wednesday until 23:00 on Thursday.</p>

<p>Prof Robin May, chief scientific officer at the UKHSA, said this was only the second time they had issued the red heat health warning - the last time in July 2022.</p>

<p>Speaking on BBC Radio 4's Today programme, he said the warning "signals a very widespread threat" from the heat, including threats "to people who generally think of themselves as not being particularly threatened by heat".</p>

<p>"Often we are warning about the vulnerable, the elderly, the young, but in this case we're also warning otherwise healthy people in their prime of life to take very cautious steps, because this heat is going to be quite intense and can have very serious life threatening effects even in people who are completely fit," he said.</p>

<p>Matthew Hopkins of the acute and ambulance network for the NHS alliance told the Today programme he expected demand on emergency services to increase over the next few days during the extremely hot weather period.</p>

<p>More than 300 schools across England and Wales are planning to be either partially or fully closed on Tuesday and later this week because of the weather.</p>

<p>Others are also closing early on Wednesday and Thursday to protect children from the heat, with some pupils being told they can wear PE kit rather than full school uniforms for those days.</p>

<p>The Department for Education does not itself "normally advise schools to close" and instead issues guidance on how best to manage high temperatures.</p>

<p>There will also be travel disruption for those travelling by car, rail and air, the Met Office warned.</p>

<p>On the National Rail network, passengers have been urged against undertaking non-essential travel and to make sure they are carrying water.</p>

<p>GTR - the UK's largest train operator - said it will suspend the Gatwick Express from early afternoon on Wednesday and Thursday. The airport will still have services via Thameslink and Southern trains.</p>

<p>The operator will also implement safety speed restrictions across the next two days, with fewer trains on Thameslink, Great Northern and Southern lines.</p>

<p>GTR passengers can get refunds for tickets they have bought for Tuesday and the next couple of days if they will no longer be travelling.</p>

<p>Avanti West Coast also said it would run fewer train services between Tuesday and Thursday, while Chiltern Railways has reduced its services by more than half over those three days.</p>

<p>National Rail explained that heat can cause a number of issues including overhead lines expanding and rails buckling.</p>

<p>The RAC said it is anticipating breakdown assistance will "increase significantly as temperatures peak", adding that it was already dealing with 10% more breakdowns than usual for this time of year.</p>

<p>Meanwhile, ceremonial guard changes in London and Windsor have been cancelled on Tuesday, Wednesday and Thursday in a bid to reduce risks for the military personnel, horses and the public.</p>

<p>Less severe amber weather warnings are in place until Friday for parts of south and central England and parts of Wales.</p>

<p>Tuesday's hot and humid weather was prefaced by <a href="/news/articles/ckg84g3zv7po" target="_blank" rel="noopener noreferrer">thunderstorms in the early hours, with some 29,000 lightning strikes recorded in the south</a>, the Met Office said.</p>

<p>The storms caused flash flooding and travel disruption across parts of England, with the London Fire Brigade reporting that it responded to 400 calls overnight.</p>

<p>Emergency services said two house fires in London and one in Bristol were believed to have been caused by lightning strikes.</p>

<p>There were also power outages in south-west England, with hundreds of homes briefly without electricity on Monday evening, according to the National Grid.</p>

<p>The immediate cause of the heatwave is a "<a href="/news/articles/c62rrj66p3eo" target="_blank" rel="noopener noreferrer">heat dome</a>" - an area of high pressure that becomes "stuck", trapping warm air underneath it.</p>

<p>While it is difficult to link individual extreme weather events to climate change, scientists say climate change makes heatwaves more frequent and more intense.</p>

<p>Over the last 30 years, Europe has been warming by 0.56C per decade, according to the Copernicus climate service - enough to make heat extremes significantly more severe.</p>

<p>The UN warned on Thursday that global average temperatures were likely to continue at or near record levels this year and for the next four years.</p>
