dr Agostinho Sousa, head of extreme events and public health at the UKHSA, said: “Temperatures will feel very warm again this week, particularly in the southern and central parts of the country.

“We want everyone to be able to safely enjoy the warm weather when it arrives, but remember that heat can quickly affect health.

“It’s important to ensure people who are more vulnerable – elderly people living alone and those with pre-existing conditions – are prepared for the hot weather.

“The most important advice is to make sure they stay hydrated, stay cool and take steps to prevent their homes from overheating.”

The Met Office’s deputy chief meteorologist Dan Rudman said: “Thanks to ongoing high pressure over the UK, temperatures are set to rise by the day this week and an extreme heat warning has been issued.

“Temperatures are expected to peak at 35C on Friday and Saturday, or even an isolated 36C on Saturday. Elsewhere, temperatures will drop well into the high 20s and low 30s Celsius.
