This is what the Met Office is warning to expect as thunderstorms hit the region this week:
- Spray and sudden flooding could lead to difficult driving conditions and some road closures
- There is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds
- There is a slight chance that power cuts could occur and other services to some homes and businesses could be lost
- There is a small chance that some communities become cut off by flooded roads
- Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services
- There is a small chance of fast flowing or deep floodwater causing danger to life
A Met Office spokesman added: “Whilst some places will miss them, thunderstorms and areas of heavy rain will develop quite widely on Wednesday across the southern England.
“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.”
