Environment Agency flood duty manager Sarah Cook said “persistent heavy rain and thunderstorms” could lead to some property flooding and travel disruption.

She said: “Persistent heavy rain and thunderstorms could lead to significant surface water flooding on Monday across parts of England.

“The impacts could include localised flooding in urban areas and fast-responding catchments, including some property flooding as well as travel disruption. The risk from river flooding remains low.

“Environment Agency teams are out on the ground and ready to support local authorities in responding to surface water flooding.

“We urge people to plan their journeys carefully, follow the advice of local emergency services on the roads and not to drive through flood water – it is often deeper than it looks and just 30cm of flowing water is enough to float your car.

“People should check their flood risk, sign up for free flood warnings and keep up to date with the latest situation as well as following @EnvAgency on X, formerly Twitter, for the latest flood updates.”

As of 7.40am, 13 flood warnings – meaning flooding is expected – were issued for England by the Environment Agency.

Areas affected by the flood warnings include Atherstone in Warwickshire, Leighton Buzzard and Luton in Bedfordshire and parts of London including Wimbledon and South Ruislip.
