An area of the UK stretching from the North West to the South East of England is officially experiencing a heatwave, the Met Office has said.
A heatwave is defined as three consecutive days with daily maximum temperatures meeting or exceeding the heatwave temperature threshold.
The threshold varies in each county, with the highest of 28C in and around London, and the lowest, 25C in Scotland, Northern Ireland and North of England.
It comes as weather alerts for thunderstorms remain in place for Scotland and Northern Ireland after much of the UK was hit by heavy rain, hail and lightning on Monday.
