A yellow heat health alert has been issued by the UK Health Security Agency (UKHSA) for parts of England and will last from 12pm on Monday August 11 until 6pm on Wednesday August 13.
The warning comes as Tropical Storm Dexter brings the potential for a fourth summer heatwave with temperatures set to climb to up to 34C in some areas.
Brits can also expect warm, muggy nights as Storm Dexter brings "draws warm air up from the southwest across the UK", according to the Met Office.

The Met Office forecasts highs of 26C for London and the southwest of England.
By Monday, temperatures are likely to be in the low 30Cs for much of England and Wales.
"We're confident that temperatures will increase markedly by the start of next week, reaching the low 30s Celsius in parts of England on Monday and perhaps the mid 30s in a few places on Tuesday," Met Office deputy chief meteorologist Steven Keates said.

"However, the length of this warm spell is still uncertain, and it is possible that high temperatures could persist further into next week, particularly in the south."
"Ex-Dexter sets the wheels in motion for an uptick in temperatures, but the weather patterns then maintaining any hot weather are rather more uncertain".
It comes after Storm Floris hit the UK on Monday this week, leaving more than 32,000 people across Scotland and the North East of England without power.
