Some areas could see 15 to 20 mm of rain in less than an hour and 30 to 40 mm within a few hours.

Met Office forecaster Dan Stroud said: “The (rainfall) is likely to lead to issues on roads with issues of surface water, so a risk of localised flooding.

“As with the nature of showers, one place can actually have a bit of a deluge and just a few miles up the road it could be as dry as a bone.”

There is a chance of power cuts and other services being disrupted for some homes and businesses.

The Scottish Environment Protection Agency (SEPA) has 14 flood alerts - the lowest category - across Scotland, including in Aberdeenshire, West Central Scotland and Fife.  

However, sunny spells are set to replace the wet and windy weather as the week draws to a close, the Met Office said.

By Thursday the UK will see a mix of sun and showers until high pressure from the western coast of England will help “slowly kill” off the rain in time for the weekend.

Mr Stroud said: “It’ll become generally dry with sunny spells during the course of the weekend, temperatures generally slightly above average, so the sunshine is going to feel quite pleasant.”
