The heatwave warning for north-west England has been raised to "level three" by the Met Office.
It said the hottest weather was expected over western England on Friday, with the east becoming cooler.
Level three warnings are in place for the South West and the West Midlands, but warnings for south-east England and London have been reduced to level two.
It was the hottest day of the year in Scotland, Wales and Northern Ireland.
