Thunderstorms are on the way for the capital as weather warnings are put in place for London following a heatwave.
Temperatures are expected to stay hot at around 26 degrees, but a torrent of rain is predicted to fall by 6pm, a mere two days after the hottest September day in nearly 70 years .
The Met Office have issued weather warnings for London and said: "Slow developing thunderstorms may develop later today (September 15), leading to locally torrential downpours with the risk of of hail and frequent lightning."
They warned: "Please be aware that whilst many places will miss them, there is the risk of flash flooding where they do occur."
Chief forecaster of the Met added: "Isolated thunderstorms may break out later this afternoon and through the evening.
"Some locations could see 30-40mm an hour, bringing the possibility of flash flooding, particularly in urban areas and lightning could cause disruption to power supplies."
Areas such as Harrow and Uxbridge should be prepared for flooding, having witnessed havoc earlier in the year due to bad weather.
