"Some areas of heavy rain will move north-eastwards during Sunday and into Monday across parts of southern England and Wales with some locally torrential downpours and thunder possible.

"Many areas will see rain at times but the extent of the most intense and thundery downpours will be limited.

"Only small areas are likely to see these downpours at any one time. This could result in some disruption, with sudden flooding of roads, transport routes, homes and businesses possible locally.

"Frequent lightning in association with the heaviest rain may also temporarily disrupt power supplies. However, given the hit and miss nature of the heavy rain and thunderstorms, many places will likely see little or no impacts."

The Met Office chief forecaster says:

"Areas of thunderstorms and rain will move northeastwards across parts of southern England and Wales during Sunday and into Monday.

"These are likely to affect southwest England and Wales on Sunday afternoon before the risk area gradually transfers East and North during Sunday evening and into Monday.

"Whilst torrential rain and thunderstorms could give as much as 30 mm or even possibly 40 mm in an hour in places these are not expected to occur at the same time across the warning area - rather only small areas will be affected at any one time."
