Met Office issues yellow heat alert warning as England to be hit by hot weather in DAYS

The North West, Yorkshire & Humberside, East Midlands, West Midlands, East of England, London, South East and South West all face yellow heat warnings.

The North East is the only English region facing a green heat warning over the same time frame.

The warning, jointly issued with the UK Health Security Agency, starts at 8am on June 24.

It remains in place until 5pm a few days later on June 27.

Britons have been warned the rise in mercury could result in an increase in the use of healthcare services, an increase in the risk of mortality amongst vulnerable and elderly people, a threat of clinical risk assessment in care settings, and an impact on the ability of services to be delivered.

Looking ahead to Sunday to Tuesday, the Met Office said: “High pressure building to bring a lot of dry and sunny weather from Sunday.

“Becoming more widely very warm next week, locally hot and humid for some by Tuesday.”

LATEST DEVELOPMENTS:

The national weather service’s deputy chief meteorologist Dan Rudman added: “Heatwave conditions need to remain in situ for three consecutive days, and by the beginning to middle of next week it is possible that some parts of the UK could be reaching heatwave thresholds.”

Temperatures will hit 23C in London on Saturday, with Manchester and Belfast also getting into the low twenties.

Sunday will see a further spike as Cardiff joins the growing list of major cities hitting 20C.

However, temperatures will go up a notch on Tuesday afternoon.

The Met Office is forecasting 26C in London, 21C in Cardiff, 22C in Manchester and 20C in Glasgow.

Temperatures will likely remain in the low twenties for much of the UK on Wednesday and Thursday.

However, a separate Met Office warning suggests London, parts of the South East and East of England could witness mercury hitting 29C.

Much of England and parts of South Wales could also see a spike of up to 27C.
