A DAY of thunderstorms and heavy showers is forecast for Sussex tomorrow.
The deluge is expected to hit Friday after days of record-breaking temperatures across much of Britain.
The Met Office has issued an amber weather warning across most of south and mid-west Wales, as well as areas including Sussex, Gloucestershire, Wiltshire, Somerset, Devon and Hampshire.
Slowly moving heavy showers and thunderstorms are forecast between 10 a.m. and 10 p.m.
In some places 20-25mm of rain is expected in less than an hour, with the possibility of 40-50mm within two to three hours.
People must expect spray and sudden flooding, which can cause difficult driving conditions and road closures.
Train and bus services could be delayed or canceled in locations subject to flooding and lightning strikes.
There is a small chance of power outages and other services to some homes and businesses could be lost, meteorologists said.
It follows a week in which Britain has recorded temperatures above 40C for the first time, with a tentative reading of 40.3C on Tuesday in Coningsby, Lincolnshire.
Sussex also recorded its highest provisional temperature when the mercury reached 37.6C in the village of Herstmonceux.
