A thunderstorm warning has been issued for parts of Hampshire - including Andover and Alton, and areas along the A303 south of Basingstoke.

It is in place from midday today (28 June) through to 10pm.

Some parts could get up to 60mm of rain in a few hours.

The Met Office says: "Following clearance of overnight heavy rain, there is the potential for thundery downpours to develop across parts of southern England on Monday afternoon, lasting well into the evening. Where these form, they could prove to be slow-moving and produce large amounts of rainfall, with 20 to 30 mm falling within an hour and perhaps a few places seeing 50 to 60 mm in 2-3 hours. Lightning, hail and gusty winds may prove additional hazards in a few locations."

What to expect

  • 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 small chance of fast-flowing or deep floodwater
  • Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services
  • There is a slight chance that power cuts could occur and other services to some homes and businesses could be lost

There is more advice on travelling in thunderstorms and staying safe in thunder and lightening on the Met Office website.
