The UK government, via the UK Health Security Agency (UKHSA), issues amber heat health alerts for parts of England as a heatwave brings temperatures of around 30C and above. Multiple outlets report that the alerts begin from Thursday afternoon or midday and run until Tuesday next week, covering a multi-day period of hot weather.
Sky News says the warning applies to parts of England from this afternoon, while other reports describe it as affecting much of England. The alerts are framed as a public health measure to help people, particularly those most at risk from heat, prepare for potentially harmful conditions.
Several sources also link the timing to forecasts suggesting the heat could feel hotter because of humidity. The Evening Standard and other reports note forecasters predict conditions may be even more intense than those experienced during earlier warm weather in May. The alerts remain in force through the stated end date, with local areas and vulnerable groups encouraged to follow UKHSA guidance during the hottest period.
