The Met Office has issued a Yellow Weather warning for thunderstorms for Herefordshire.
Slow-moving heavy showers and thunderstorms will break out across many parts of the UK on Tuesday afternoon.
Some places will miss them, but where they do occur they will bring torrential downpours with 25 to 35 mm rain falling in an hour and perhaps 40 to 50 mm in 2 to 3 hours in one or two places. Lightning and hail will be additional hazards.
These showers and thunderstorms will only slowly die out through the evening, but may persist across northwest England, southwest Scotland and perhaps eastern Northern Ireland into the early hours of Wednesday morning.
