Hot weather sparks thunderstorm warning for Cornwall

Hot weather sparks thunderstorm warning for Cornwall

Published by Sarah Yeoman at 11:24am 24th June 2020. (Updated at 11:16am 25th June 2020)

A thunderstorm warning has been issued for Cornwall as we bask in glorious sunshine and high temperatures.

The Met Office has issued a yellow alert which is in force from 4pm on Thursday through until 9am on Friday.

Although most places will remain dry, there is a chance that any rain could cause flooding and difficulties on the roads.

It comes as a level two heat health alert remains in force for Cornwall and most of the country, as temperatures in the Duchy reach the high twenties.

What to expect:

  • 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
  • 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
  • There is 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

"Thunderstorms may develop across parts of western UK late on Thursday afternoon and into the evening.

"A larger area of thunderstorms is then expected to move northeastwards overnight into Friday.

"Many places will miss the worst of the storms but where they do occur torrential downpours could bring 30-40 mm rain in less than two hours.

"Lightning and hail are also likely to be additional hazards."
