Heat health alert – soaring ‘temperatures peaking at 30°C’

A heat health alert has been issued for London, including Clapham, and the South East with temperatures set to peak at 30°C.

The alert – issued by the UK Health Security Agency and the Met Office - runs from 9am on Friday through to Monday morning.

The yellow alert carries a warning that there could be health issues for vulnerable groups over the age of 65 or with existing health conditions.

These include respiratory and cardiovascular diseases. There is also the potential for indoor environments, including health and care settings, to become very warm.

Dan Harris, Deputy Chief Meteorologist at the Met Office, said: "Temperatures will rise later this week and into the weekend, with a plume of warm air being drawn in from the south.

"Temperatures over the weekend could peak around 30°C in some parts of England and remain well above average overnight through the weekend.

"Coupled with the rise in temperatures is an increase in the likelihood of some potentially heavy and thundery showers, which could bring some localised disruption for some from late on Friday and into the weekend, though it is not possible to be definitive about exact details this far from the potential event."

The yellow alert carries a warning that there could be health issues for vulnerable groups over the age of 65 or with existing health conditions.

Dr Agostinho Sousa, Head of Extreme Events and Health Protection at the UK Health Security Agency, said: "In the coming days we are likely to experience our first sustained period of hot weather of the year so far, so it's important that everyone ensures they keep hydrated and cool while enjoying the sun.

"Forecasted temperatures this week will primarily impact those over the age of 65 or those with pre-existing health conditions such as respiratory and cardiovascular diseases.

"If you have friends, family or neighbours who you know are more vulnerable to the effects of hot weather, it is important you check in on them and ensure they are aware of the forecasts and are following the necessary advice.''

The alert covers London, the South West, the East Midlands, West Midlands, South West and the East of England.
