It will no doubt worry those heading to Glastonbury at the end of the month. Wimbledon, which takes place between June 27 and July 10, and The Royal Ascot, which starts today, are also likely to be affected.

Marco Petagna, a Met Office forecaster, said: “After a dry start to June, the rest of the month does look to be unsettled.

“For this week, the weather is looking wetter and wetter with an increase in thunderstorms and heavy rainfall.”

Alison Baptiste, flood-risk duty manager at the Environment Agency, said: "Heavy rain showers across parts of England over the next few days could lead to some surface water flooding with disruption to roads and travel possible.

"Environment Agency teams are out working on the ground and will support local authorities in responding to surface water flooding. Please don't drive through flood water: remember just 30cm of flowing water is enough to move your car."
