The Met Office is warning that flash flooding and frequent lightning is possible in Herefordshire on Sunday.
The Met Office Weather Warning says:
“Thunderstorms and areas of rain are expected to develop over parts of England and Wales during the early hours of Sunday. Torrential downpours are likely in a few places with parts of the Midlands, East Anglia and southeast England most at risk. Some places could see 15-20 mm in an hour, and perhaps up to 50 mm before storms fade, and hail may affect a few spots. These thunderstorms will slowly spread into southern parts of northern England on Sunday morning before easing. Further south, drier conditions briefly develop on Sunday morning before further showers and thunderstorms develop over some parts of southern England, Wales, the Midlands and East Anglia later. These may give some heavy downpours with a further 10-20 mm possible in some places.”
