The Met Office has issued a yellow weather warning for heavy rainfall for large parts of Western England and Wales from 18:00 BST on Tuesday until 12:00 on Wednesday.

There is a small chance of properties and businesses to experience flooding while travel disruption is likely, the Met Office has warned.

Rain is expected to develop in southwest England late afternoon on Tuesday, before becoming heavier and expanding north in the evening and overnight into Wednesday.

The Met Office said: “Many places will see around 10-20 mm of rain, but there is a chance some locations may see considerably more than this over a 6 hour period, most likely parts of southwest England and south Wales.

“A few places may see 50-80 mm of rainfall in 6 hours. Isolated thunderstorms are also possible in the south of the warning area, with lightning an additional hazard.”

A second warning for heavy rain has been issued for much of Northern Ireland for Wednesday morning.

“Some high ground of South Armagh and South Down, and particularly the Mournes, could see 50-80 mm.”

Despite the downpours, UK temperatures over the next few days are forecast to be above average for the time of year.

East Anglia and the Home Counties could reach 22C (71.6F) and most regions are projected to have temperatures in the mid-teens on Wednesday, Thursday and Friday.

This comes after some counties in the UK experienced more than 250% of their average rainfall in September, with six counties in England experiencing record levels.
