More than two weeks of rainfall is expected in 24 hours in parts of Britain on Friday, bringing strong winds with it. The first major storm of the autumn is set to hit the north east throughout the day, and in Northern Ireland and the south of Scotland by mid-afternoon.
Experts warn that after an unusually-wet August the saturated ground is at higher risk of flooding across the UK. South-west England, south Wales and especially Gloucestershire have already been battered since the early hours, causing flash floods.
Paul Mott of MeteoGroup, the weather division of the Press Association, warned that in the next 24 hours up to 50mm of rain was expected, which is typically the amount that falls over a fortnight in September.
He said gusts of up to 50mph would make it a "thoroughly miserable" day and advised people to take care on the roads and leave extra time for their journeys, especially if commuting.
Mr Mott said: "We're not expecting widespread flooding, but it's going to remain unstable over the weekend."
Downpours over Thursday night led to road closures in the county and firefighters had to pump out floodwater from homes.
