BRITS are set for warmer weather this week after storms dumped a month's worth of rain on the UK in a day, turning roads into rivers and grounding flights.
Floods and power cuts are expected as heavy rain batters Britain with yellow weather warnings for thunder in some areas and almost two dozen flood alerts – but temperatures are set to remain mild.
The UK is set to warm up throughout the week, with the chance of the mercury topping 20C by the weekend.
Stephen Dixon, a spokesperson for the Met Office, said: "Above average temperatures will continue through the week, although there will be a continued unsettled theme with periods of showers and high winds at times.
"Looking at temperatures in isolation, they will continue to rise through the week and into the weekend, possibly reaching above 20C in the southeast on Saturday and Sunday.
"Temperatures of this nature aren’t unheard of in October, but they’re certainly unusual, especially later in the month."
The warmer climes are due to a south-westerly air flow dragging warmer air in from the continent.
Mr Dixon added: "Although warm, the weather will still feel quite unsettled for most… Breezy conditions will also remain, meaning it might feel cooler for most.
"The best of any sunshine is likely to be early on Tuesday, before cloud, winds and rain builds in from the southwest towards the evening."
It comes on a day when there are 22 active flood alerts, meaning flooding is possible.
Areas affected stretch from the Mid Bristol Avon Area to the Stoke Trent region.
Meanwhile the Met Office issued yellow weather warnings for thunderstorms with the downpours battering much of the country.
Two warnings covered the period from 4am on Sunday to 5am on Monday, covering all of the south east and most of the south west.
The affected area then stretched north right the way up the east coast.
Cities as far north as York and Middlesbrough are still feeling the brunt.
The Met Office said Brits should be wary of sudden flooding and possible power cuts, with traffic delays and other transport issues where floods and lightning strikes hit.
There is also a possibility that small communities could be temporarily cut off by flooded roads.
A number of flights from Heathrow Airport were delayed due to the wild weather with a large number of planes said to be in a holding pattern, reported the Daily Mail.
Flights out of Gatwick were similarly affected as thunderstorms swept the nation last night, with air traffic control restrictions in place.
As rain poured down, motorists were unable to get through an underpass in Acton Town, West London, unless they had a 4×4.
Some drivers who attempted to go under the bridge got stuck and were forced to call AA.
Scotland, Wales and Northern Ireland, as well as the North West, avoided the worst of the weather.
However, these areas are still set to see long spells of rain, many of which could be heavy.
It comes after four flood alerts were issued on Thursday and a yellow weather warning for thunderstorms and lightning.
A jet stream swept across the UK, bringing with it the wet weather and prompting the alert.
The UK has been experiencing temperatures much warmer than usual for this time of year – and that’s set to continue.
October's highest temperature ever recorded in the UK was 29.4C in the small market town of March, Cambridgeshire, on the first day of the month in 1985.
Forecasters have been hailing the warm weather as an Indian Summer.
