Met Office meteorologist Kathryn Chalk said in a forecast on YouTube: "After an unsettled Sunday, most of us should see a good deal of sunny spells as we go through Monday but we still hold on to some heavy spells of rain so it is still a damp start so take care during rush hour there could be some spray on the road.
The Met Office forecast a wet and windy start to the week, with heavy showers expected to batter large parts of Britain.
"Frequent showers across Northern Ireland and parts of Scotland where they could turn heavy, possibly with the odd rumble of thunder.".
Those in the south and south east of England, particularly along the coastline, are also due to be hit by torrential downpours into the afternoon.
As the morning progresses, bands of rain are forecast to move north eastwards, which will see areas across the Midlands affected later.
