What to expect
- Flooding of homes and businesses could happen quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds
- Fast flowing or deep floodwater is possible, causing a danger to life
- Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services
- Spray and sudden flooding could lead to difficult driving conditions and some road closures
- Some communities might become cut off if roads flood
- Power cuts might occur and other services to some homes and businesses could be lost
What should I do?
Reason for update
Warning updated from a very low likelihood to a low likelihood warning.
Further details
Thunderstorms and areas of heavy rain will develop quite widely across much of England and Wales. The extent of these thunderstorms will be more widespread than on Monday, though some spots will still miss storms and remain dry. 20-30 mm of rain is possible within an hour, but where areas of thundery rain become slow-moving, some places could see 50 mm in less than three hours. There is a chance that higher totals could occur in a few spots over the course of the day. Hail and frequent lightning are likely additional hazards for some places. There remains some uncertainty at this stage in regional and county level focus.

While some places stay dry, others are likely to see thunderstorms with torrential rain during Wednesday, bringing possible disruption.
What to expect
- Flooding of homes and businesses could happen quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds
- Fast flowing or deep floodwater is possible, causing a danger to life
- Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services
- Spray and sudden flooding could lead to difficult driving conditions and some road closures
- Power cuts might occur and other services to some homes and businesses could be lost
What should I do?
Reason for update
The yellow area has been extended northwestwards to cover more of England and moving into southeast Wales, the start time brought forward, and the likelihood of impacts increased.
Further details
Whilst some places will miss them, thunderstorms and areas of heavy rain will develop quite widely on Wednesday across central, southern and eastern parts of England and southeast Wales. 20-30 mm of rain is possible within an hour, but where areas of thundery rain become slow-moving, some places could see 60 mm in less than three hours. A few spots could see more rainfall than this still, whilst hail and lightning may be additional hazards. .
