The Met Office has issued two yellow thunderstorm weather warnings for Winchester this week. 

After a few days of glorious sunshine, forecasters have warned that there might be heavy rain, with possible hail and strong winds. 

The first thunderstorm weather warning is in place from midday on Wednesday, July 31, until 11.59pm and covers most of the south including London. 

Another warning will then take effect on Thursday, August 1, from midnight until 11.59pm, this time covering England and Wales. 

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.

"Whilst there is some uncertainty, thunderstorms may affect southeast England during the early hours of Thursday, perhaps also extending into parts of East Anglia. Where these occur, rain accumulations of 25-40 mm are possible in 1 hour, with a small risk of over 60mm in 2-3 hours, and accompanied by frequent lightning at times."

Forecasters have warned drivers to be careful on the roads due to spray and sudden flooding.
