A yellow thunderstorm warning has been issued by the Met Office for Powys, which will hit just as the heatwave is on the decline.

The weather warning begins at 6am on Monday, August 15 and is in place for the rest of the day after that.

Powys is completely covered by the warning, as is the whole of Wales, meaning there are no areas of respite.

This weather warning will come shortly after the heatwave is on the decline in the area, which saw an amber weather warning for extreme heat issued.
