An eight-hour thunderstorm with 50mph winds will ravage Britain today – before it snows tomorrow.
Yellow weather warnings have been issued for parts of the UK including London, Birmingham and Cardiff.
The Meteorological Department said there would be heavy rain, thunder and “very strong winds” this morning.
“It is currently raining heavily and with thunderstorms over South West England, Wales and the Midlands,” the forecaster said.
He said, “There are some strong winds along with the rain, which will make travel difficult in many places.
“There is a small chance that floodwaters, lightning strikes, hail or strong winds could cause rapid flooding of homes and businesses with damage to some buildings.
“Spray and flash floods can make for difficult driving conditions and some roads may be closed.”
The warning has been put in place between 4 am and 12 noon today.
Gusts of up to 50mph are expected.
A frightened driver had to rescue a car that was stuck in flooding due to torrential rains in many parts of Britain this morning.
In Fowey, Cornwall, firefighters struggle with floodwaters to reach the car after 7 a.m.
Cornwall Fire and Rescue tweeted: “Vehicle off road after being hit by flood waters.
“The driver was not injured but had to be helped by the car due to the depth of the water and the condition of the vehicle.”
In many areas there was a storm, there was chaos due to thunder and lightning.

snow is a go
Meanwhile, there is a chance of snow tomorrow – and it is likely to remain cold until the end of the month.
The first snowfall for the country is on Thursday, but thankfully for many of us, we will be unaffected by the headaches that snowfall can cause.
Met Office forecaster Anne Shuttleworth said: “On Wednesday night we will see a further southward move through Britain, and it may bring with it some snow.
“But it is confined to the high ground in Scotland. For most of us we will see rain on that front.”
The cold snap is tipped to last until Halloween, with hail and rain on an arctic chill.
The long-range weather forecast of the Meteorological Department said that the temperature is likely to drop next week.
