A flood warning has been issued to parts of the UK, with two weeks worth of rain due to fall in 24 hours.
South West England and South Wales have been battered since the early hours and the rain is expected to head north east throughout the day, hitting Northern Ireland and the south of Scotland by mid-afternoon.
Meteorologist Paul Mott warned that up to 50mm of rain is expected in the next 24 hours, as much as would be typically seen in a fortnight in September.
Experts said that an unusually-wet August has left the ground saturated and added to the risk of flooding.
Gusts of up to 50mph will make it a "thoroughly miserable" day, and commuters have been advised to leave extra time for their journeys because of the weather.
"For most areas it will be a wet and miserable day, and we would advise people to take care on the roads and allow extra time for their journeys", Mr Mott said.
"There will be some localised flooding in Wales and the North East in areas that are prone to it, but we're not expecting widespread flooding."
"It's going to remain unstable over the weekend. There will be rain, sometimes heavy rain, through the UK with northern England bearing the brunt of it."
The Met Office has issued a severe weather warning for the region until this evening and say around 2in of rain is expected.
Severe weather warnings are also in force for Wales, the North West, North East, South West and South East of England as well as London.
