Up to 20mm to 30mm of rain could be seen in one hour with the potential for flooding in some areas.

A Met Office spokesman said: “Although some places will avoid them, there is a chance that thunderstorms will develop more widely as Monday progresses.

“Storms are likely to be already underway for Northern Ireland and parts of Scotland by early Monday, before also developing across parts of England and Wales by late morning and afternoon. Storms should begin to weaken from the west later.

“Very locally, 20-30mm of rain is possible in an hour and up to around 50mm in three to six hours. Hail and frequent lightning are also possible.”
