The Met Office has issued this weather warning on Friday 10 May.
The warning is in force from 1 pm until 11 pm on Sunday 12 May.
Heavy showers and thunderstorms are likely to break out in the south and west of this area early Sunday afternoon, moving steadily north whilst growing into larger areas of heavy rain before clearing through the late evening.
Some intense downpours are possible in a few places, giving up to 30 mm in less than hour and perhaps 50 mm over 2 to 3 hours leading to surface water flooding. Large hail, frequent lightning strikes and possibly strong wind gusts will be additional localised hazards.
Warning area adjusted to remove parts of south and southwest England and West Wales, whilst including more of northern England. Period of validity has been delayed by 1 hour, whilst the likelihood of impacts has been increased.
