Thunderstorms and lightning bring risk of flooding to parts of England and Wales
The Met Office is warning of gusty winds, large hail, and even the potential for power cuts. Yellow heat health warnings also remain in place for much of England until Friday
A yellow weather warning has been issued for heavy showers and thunderstorms Wednesday and Thursday, including the potential for flooding and power cuts.
The Met Office predicts some areas could see as much as a month's rainfall in a few hours.
Large downpours are forecast tonight in the south of England - from Hampshire to Kent, with London and Essex also set to be hit.
Those places could experience up to 3cm (1in) of rain within an hour.
From early on Thursday morning, the warning area extends to cover most of England and Wales, as far north as Northumberland - up to 4cm (1.5in) could be expected in an hour.
There is also a small risk tomorrow of more than 6cm (2in) in two to three hours, along with frequent lightning at times, although that is more likely in southeast England and East Anglia.
Scattered heavy showers and thunderstorms are expected to develop throughout Thursday afternoon and evening across parts of central, southern and eastern England, and potentially South Wales.
Forecasters say there is a risk of gusty winds, large hail, as well as flooding, which could lead to difficult driving conditions, road closures, and disruption to trains and buses.
They are warning homeowners and businesses that power cuts might also happen.
It is likely to feel sticky on Wednesday and Thursday - when it could remain as warm as 30C (86F) or above - before dropping off next week.
