Thunderstorms are expected in more parts of the country after the Met Office extended its yellow warning further north and east.
Following record high temperatures for the UK on Tuesday, a yellow thunderstorm warning is now in place for much of the South and West of England, and east Wales.
There have been thunderstorm warnings in place since Wednesday, which have now been extended into Friday and reach northeast Wales and Merseyside, as well as southeast England.
Areas affected also include most of south and mid-west Wales, Gloucestershire, Wiltshire, Somerset, Devon, Hampshire and Sussex.
A yellow warning is in place from 10am until 10pm on Friday.
The Met Office is warning that some areas will remain dry but other places could see “slow-moving heavy showers and thunderstorms” developing from mid to late morning before dissipating in the evening.
Where thunderstorms occur, 20-25mm of rain could fall in less than an hour, while one or two places could see 40-55mm in two or three hours.

The Met Office said where there are thunderstorms, people should expect spray and sudden flooding that could lead to difficult driving conditions and some road closures.
There could also be train and bus delays and cancellations where flooding or lightning occurs.
And there is also a “slight chance” of power cuts.
