THE Met Office has issued a severe ’yellow’ weather warning with heavy showers and thunderstorms expected to affect Surrey and Hampshire this weekend.

Very warm and humid conditions will lead to thunderstorms developing across parts of southern England, the south and west Midlands and Wales on both Saturday and Sunday.

Thunderstorms will produce torrential rain and hail in places with up to 30 mm falling in an hour, while some places may miss the worst of the heavy rain.

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 also a small chance of fast flowing or deep floodwater causing danger to life, and 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.

The Met Office warns there is also a small chance that some communities become cut off by flooded roads.

There is a slight chance that power cuts could occur and other services to some homes and businesses could be lost.
