Torrential rain is expected to cause flooding in some parts of the UK on Friday.
The Met Office has issued an amber flood warning for South Wales, where homes are likely to be affected and communities could be cut off due to water on the roads.
Disruption to transport services and power lines is also expected in the region from 9am and lasting until Saturday, with a chance of lightning and hail forecast.
A yellow weather warning for rain which could cause some disruption in Cornwall, Devon, and the southern half of Wales is also in place from 7am.
A band of heavy rain and coastal gales hit the South West on Thursday night, bringing persistent showers throughout Friday.
Elsewhere, there will be some rain concentrated in Aberdeen, but a cloudy outlook with bright spells expected for the rest of the UK.
Temperatures are set to be mild across the country, ranging from around 9C (48F) in the north of Scotland to 13C (55) in Plymouth.
The rain is set to ease over the weekend, leaving bright spells and blustery showers for most places, with the wettest weather staying in western areas.
Mild temperatures in the low teens are also predicted to last throughout the weekend before chillier weather moves in on Sunday night.
Meanwhile, experts have warned the next couple of months are likely to be wetter than normal in the UK, raising the prospect of further flooding to come.
Will Lang, head of civil contingencies at the Met Office, said that after an unsettled December, there will be colder, drier weather over Christmas and into the new year.
"Beyond that, though, our longer range forecasts for January and February have been consistently suggesting that wetter, windier and milder conditions are more likely than normal, so that wet weather will return again," he said.
