A YELLOW warning has been issued for heavy thunderstorms and lightning as Brits brace for wild weather.
The Met Office has said that buildings could be damaged today with storm warnings in place until 5am Monday morning.
However, the UK will remain warm - with humid conditions set to linger into next week.
Forecaster have warned that homes and businesses could be flooded quickly.
They say some buildings could be damaged from floodwater, lightning strikes, hail or strong winds.
And there is a chance that power cuts could occur and other services to some homes and businesses could be lost.
Meanwhile there is a risk of travel chaos - as where flooding or lightning strikes occur trains and buses could be cancelled.

Tomorrow forecasters say a band of heavy rain will sweep across the south, with a risk of thunder, moving northwards through the day.
It comes after four flood alerts were issued on Thursday and a yellow weather warning for thunderstorms and lightening.
A jet stream was sweeping 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.

BBC meteorologist Louise Lear said: "On Monday we've got some wet weather clearing Scotland, sunny spells and scattered showers behind [them]....still the risk that some of those showers could be thundery, chiefly out to the west.
"The best of the dry weather once again remains for eastern England.
"Again we are going to see those temperatures into the high teens, above where they should be this time of year.
"That's going to be the trend as we go through the week ahead. It's going to be relatively mild, but we've got more showers to come towards the end of the working week."
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.
