Wales weather warning: Thunderstorms set to replace heatwave

There is a small chance of flooding and power cuts, forecasters warn

The heatwave is set to come to end this weekend after forecasters issued warnings for rain and thunderstorms covering much of south Wales.

The Met Office said "heavy, thundery showers" are likely, which could be "torrential" with the potential for up to 100mm falling in places.

Lightning and hail are also expected after Wales basked in temperatures of up to 31C this week.

There is a small chance of flooding and power cuts, forecasters warned.

The extreme heat warning, the first issued by the Met Office, was due to end on Thursday night in Wales.
