"Rain is expected to clear away during Thursday afternoon. 30-40 mm is likely to fall quite widely, with peaks of 60-80 mm over higher parts of the Brecon Beacons."

The deluge of wet weather will sweep in from the Atlantic. While yellow weather warnings are only in place for parts of the country, the entire of the UK is set to be hit by the miserable conditions.

Jim Dale, social commentator and senior meteorologist for British Weather Services, has already described the conditions facing Britain later this week as a "horror show".

"The first system comes in on Wednesday and then another arrives on Thursday and Friday," he said.

“It is a pretty miserable picture through the week, and in parts of the country we could see two to three inches of rain, which is above average for the time of year.”

The heavy rain comes just days after parts of Britain were hit by heavy snow.

Households in Cumbria have gone three nights in a row without power after up to 30cm of snow brought down power lines across the country.

A "major incident" was declared by police after the thick depth of sitting snow led to hundreds being stranded.

The melting snow means that there are already more than 20 flood warnings are in force across south-west England.

The Environment Agency has issued 28 flood warnings, mainly in Dorset and Somerset, as heavy rain is causing river levels to rise.

National Highways said the A303 in Somerset was closed eastbound between the A37/A372 at Podimore and the A359 near Sparkford because of flooding, with no time estimated for when it would reopen.
