The Met Office weather warning for Monday 17 August says: "Some heavy showers and thunderstorms are expected overnight, with further thunderstorms then developing across many areas of England and Wales during the late morning and afternoon, when they are likely to be slow moving.

"Some places within the warning area will miss the thunderstorms altogether, but where they do occur 20-40 mm of rain may fall within an hour with 50-70 mm possible in 3 or 4 hours."

"Lightning, hail and possibly gusty winds will be additional hazards."
