Public Health England (PHE) has issued a health warning as scorching temperatures are set to continue in London.

The Met Office declared a Level 3 heatwave alert yesterday, which means the hot weather has arrived in the east of England - it is forecast to last until Friday morning.

Hot temperatures during the day are likely to be accompanied by very warm nights for the rest of the week.

A level 2 heatwave alert, a warning that heatwave conditions are likely, has also been issued across London and south-east England - although many places may see warm temperatures.

It is possible that the hot weather will return for the bank holiday weekend.

As a result of the alerts, PHE is urging people to make sure support is given to those who may be at risk from the ill effects of heat.

Dr Thom Waite, consultant in public health medicine and part of the Extreme Events team at PHE, said: “Now the heatwave has arrived, people will likely be out and about more enjoying the summer sun.

“That’s why it’s really important to remember that there are some people whose health suffers in hot weather.

“Older people, those with underlying health conditions and young children may all feel the ill effects of heat over the coming days.”

Dr Waite added: “We’re urging everyone to keep an eye on those you know who may be at risk this summer. If you’re able, ask if your friends, family or neighbours need any help.”
