A yellow weather warning for heavy rain on Thursday and into Friday has been issued by the Met Office.
Isolated thunderstorms are expected to push north across southern England early on Thursday morning before developing across other parts of England and Wales during the early afternoon.
Forecasters are warning that 25-30mm of rain may fall within an hour, perhaps as much as 50mm in 3 hours, however such totals are likely to be very isolated.
While these storms may miss many places, where they do develop intense downpours are likely, bringing a low risk of sudden flooding of roads, transport routes, homes and businesses. Lightning and hail may be additional hazards.
The warning is in place from 06:00 on Thursday until 06:00 on Friday.
