A yellow wind warning has been issued for London as gusts of over 40mph are set to sweep in after a sunny weekend.
The weather alert is in place across most of England and Northern Ireland until 10pm today and the Met Office has warned of delays on roads and train journeys as well as possible power cuts.
The blustery conditions are a stark contrast following a hot weekend in the capital, with the mercury reaching 21C last Friday.
The Met Office has said Monday will be the wettest day of the week as a band of rain pushes its way south-eastwards, causing widespread rainfall across the country accompanied by strong, chilly winds.
Rush hour commuters in London will face horrible, rainy conditions on Monday morning and the Met Office has warned “Monday is classic April showers”.
Forecaster Simon Partridge said: "We've got a pretty windy day across the whole of the UK with gusts of wind up to 40-50mph pretty much anywhere across the country.
"With that, we'll have some quite blustery showers which will be slightly wintry in nature across the northern parts of the UK.
"You could get a little bit of sleet and certainly some hail so it will be a much colder feeling day."
Mr Partridge also warned that the drop in temperature may be “a bit of a shock to the system” following a sunny weekend across the country.
The highest temperature nationally was recorded in Writtle, Essex, on Saturday at 21.8C.
But the mercury is not expected to reach 15C in London again until Friday.
By then, temperatures across the country are expected to reach the low to mid-teens with slightly warmer conditions in the south.
Figures show England saw a record amount of rainfall between October 2022 and March 2024, the highest for any 18-month period since comparable data began in 1836.
