Heavy rains on Friday are expected to cause flooding in some parts of the UK.
The Meteorological Office for South Wales has issued a flood alert warning that homes could be affected and communities could be cut off because of water on the roads.
Disruption to transportation services and electrical connections is likely from 9 a.m. to Saturday, with a chance of a thunderstorm forecast.
Yellow weather warnings for rain, which could cause some disruption in parts of Cornwall, Devon and southern Wales, are also in effect from 7 p.m.
Heavy rain and coastal winds lashed the southwest on Thursday night, followed by continuous rain throughout Friday.
Elsewhere, there will be some rain in Aberdeen, but cloudy weather with bright writing for other parts of the UK.
Temperatures will be moderate around 9C (48F) in the north of Scotland to 13C (55) in Plymouth.
Due to the humid weather in the western parts, it will rain on the weekends, with bright spells and dim showers in most places.
The mild temperatures of the lower teens are also forecast to last throughout the weekend before the chili weather moves on Sunday night.
Meanwhile, experts have warned that the next two months will be more humid than normal in the UK and more flooding is likely.
After December, there will be cold, dry weather by Christmas and New Year, said Will Long, head of civil affairs at the Meteorological Office.
“Beyond that, our long-distance forecasts for January and February continue to say that humidity, ventilation and mild conditions will be higher than normal, so the wet weather will return,” he said.
