Amber extreme heat warning in force across much of the UK, with highs near 38C. North East upgraded to amber by UKHSA, matching warnings across England.
Amber heat warning hits
The UK braced for another day of extreme heat as an amber warning was set to come into force on Thursday, with temperatures forecast to soar as high as 38C. The BBC said the warning would run from 09:00 BST until 23:59 BST across Eastern England, London and the south-east, the Midlands and parts of Yorkshire and Humber, and that it would be accompanied by amber heat health alerts across all of England.
The BBC also warned that the searing heat could lead to power cuts, rail and air travel delays, and serious health impacts such as dehydration and heat exhaustion. In parallel, Sky News reported that the amber extreme heat warning would be in place from 9am until midnight and cover parts of southern and eastern England as well as parts of the Midlands, citing the Met Office.
Rail disruptions and drowning
As heat health guidance and transport warnings spread, Sky News said some train operators urged passengers to travel only if necessary, with Chiltern Railways, East Midlands Railway and Northern issuing alerts to "only travel if essential". The Independent reported that rail operators were urging passengers to only travel if necessary on Thursday as services would be disrupted because of hot weather, and it quoted Northern saying high temperatures "increase the risk of issues on the railway and with the reliability of our trains".
Sky News tied the heatwave to water risks by describing Muhammad Secka, 16, as one of at least 15 people who drowned during the heatwave in May, and it included his mother Kaddy Ceesay’s account of how police told her Mohamed was last seen in the water but was not struggling. Sky News also quoted Ceesay saying, "My child is in the water," as she described the moment she told police she would not go home while search efforts continued.
Models, infrastructure, and stakes
Meteorologist Alex Burkill said forecasting can be thrown off when models misjudge ground moisture, explaining that in previous heat waves "our models overestimated a little bit" because they underplayed moisture in the ground after thunderstorms. Sky News said Burkill warned that "it was possible \"the models are overdoing it again\"" and added that the dry ground meant less energy was needed to heat the air up, as the UKHSA and Met Office prepared for impacts.
The BBC described the health stakes in terms of amber heat health alerts already in force for England until 21:00 BST on Friday, warning of significant impacts including a rise in deaths, particularly among those aged 65 and over or with health conditions. The BBC also noted that tropical nights—where temperatures fail to drop below 20C—were on the cards as increasingly humid air spreads into western areas, while it said the heatwave was likely to last two or three days at most.
