UK weather forecast: Fortnight’s worth of rain to fall in three hours as hail, floods and thunder hit UK

A FORTNIGHT’S worth of rain will lash Britain in just three hours today as the country is hit by ferocious thunder and hail storms, the Met Office warns.

A “danger to life warning” has been issued for most of England and Wales today, with weather forecasters predicting serious flooding, blackouts and travel chaos.

After an extremely wet weekend saw flooding hit some areas, millions will have to endure more intense downpours due to the storms today.

A spokesman for the Met Office said: “Heavy showers and thunderstorms will continue to spread north-east across England and Wales, while also increasing in frequency during the day.

“In a few places there is the potential for 20mm (0.8in) to 30mm (1.2in) of rain to fall in an hour and 30mm (1.2in) to 50mm (2in) of rain to fall in three hours.

“Hail is also possible, mainly over northern England.”

East Anglia and the South East are not covered by the warning, which runs until the end of Tuesday.

The area covered by a weather warning for Wednesday includes parts of Scotland, North Wales, north England and the Midlands.

Homes and businesses are at risk of more flooding over the coming days – while lightning strikes could lead to power cuts.

Temperatures will also nosedive to highs around just 18C – a week after the country endured its hottest day ever with a high of 38.7C.
