A yellow severe weather warning for rain has been issued for Sunday afternoon through to Monday morning.The warning, which starts at midday on Sunday and ends at midday on Monday, says a band of heavy rain is likely to spread northward, with some locally torrential downpours and thunder possible.
There are early indications that this could result in some disruption, with sudden flooding of roads, transport routes, homes and businesses possible.
The Met’s chief forecaster said: “Torrential rain and thunderstorms could give as much as 30mm, possibly 40mm in an hour in places.
“It is not certain where flooding impacts may occur, but it is likely to be in a few places rather than across the whole warning area.
“Lightning strikes are also possible, which bring a chance of power cuts.”
