A weather warning has been issued for parts of England and Wales ahead of forecast “heavy rain”.

The Met Office’s yellow warning for rain is in force from 08:00 to 23:59 BST on Monday.

It covers Devon, Cornwall, Somerset, Bristol and Wales, along with parts of the north west of England.

Met Office bosses said up to 40mm of rain could fall in the space of three hours, and there is the possibility of flooding, thunder storms, power cuts and travel disruption.

“Outbreaks of rain, some heavy and thundery, will spread steadily north across the area during Monday,” the Met Office said.

“Some torrential downpours are likely in places with 15 to 20mm falling in less than an hour and as much as 30 to40 mm in three hours.

“This is likely to lead to localised flooding, slower travel times and a small chance that homes and businesses could be flooded.”
