Further details

Thunderstorms are likely to break out in some areas, particularly during the afternoon and early evening. While most places will probably miss them, where thunderstorms do occur there is a chance that in a few places up to 40 mm of rain could fall in an hour or so and 40 to 60 mm could fall in two or three hours. These torrential downpours may be accompanied by frequent lightning, whilst gusty winds and hail may also affect a few places. The exact location of the thunderstorms will be hard to pinpoint, so the warning area will be kept under review and updated if necessary.
