Another weather warning has been issued for Southampton as thunderstorms are set to hit across England. 

The Met Office has now issued a second yellow warning for thunderstorms from midday to midnight tomorrow (Wednesday, July 30). 

It comes after it issued the same warning for Thursday forecasting "torrential" rain with possible hail and gusty winds.

The new warning covers most of the South Coast including London and Salisbury.

On its website, the Met Office said: "Whilst many places will stay dry, a few thunderstorms are likely to break out on Wednesday.

"These are possible at any time, but become more likely during the afternoon and evening.

"Where these occur, 20 to 30 mm of rain is possible within an hour, and perhaps as much as 50 mm in two hours; the latter more likely across southeast England and parts of East Anglia during the evening.

"Lightning will be an additional hazard."

Drivers have been told to expect spray and sudden flooding leading to difficult conditions and some road closures. 

There is also a small chance that some communities could be cut off by flooded roads and power cuts could occur.

Meanwhile, a yellow weather warning for thunderstorms which was issued on Monday and comes into force between midday and 11.59pm on Thursday has been extended.

It will now start at midnight on Thursday morning.

"Multiple rounds of heavy showers and thunderstorms" are forecast, with some set to lead to disruption.

Spray and flooding could lead to difficult driving conditions and power cuts could occur.

Flooding of homes and businesses could happen quickly, with damage to some buildings possible from floodwater, lightning strikes, hail or strong winds, the Met Office warns.

It means the weather warning covering Southampton will last 18 hours.
