SUNSHINE across Sussex is forecast to come to an abrupt and sudden end tomorrow, with a yellow weather warning for thunderstorms issued for the south of England.

The weather service’s warning, which comes into effect from 10am tomorrow until midnight, said that thunderstorms and torrential downpours may cause travel disruption.

The Met Office said that tomorrow’s forecast could cause delays and some cancellations to train and bus services due to flooding and lightning strikes, as well as a “slight” chance of power cuts to homes and businesses.

A spokeswoman for the Met Office said: “Thunderstorms are likely to break out in some areas, particularly during the early afternoon and early evening.

“While most places will probably miss them, where thunderstorms do occur there is a chance that, in a few places, up to 40 millimetres of rain could fall in an hour and 40 to 60 millimetres could fall in two or three hours.

“These torrential downpours may be accompanied by frequent lightning, whilst gusty winds and hail may also affect a few places.

“The exact location of the thunderstorms will be hard to pinpoint, so the warning area will be kept under review and updated if necessary.”

Currently, the yellow warning covers most of the south coast of England, parts of Wales and as far north as Stoke-on-Trent and Nottingham.

Potential travel disruption from the thunderstorm could worsen travel plans for many, with rail staff due to take part in the second day of strike action tomorrow.

The Met Office’s forecast for Brighton and Hove predicts that light showers will start around midday, with temperatures still reaching highs of around 22C.

The sunshine is expected to return on Sunday, albeit with some showery intervals and with temperatures reaching a slightly cooler 18C.
