It is going to be exceptionally hot across the UK and the mercury could top 40C in an unprecedented heatwave. People have been urged to take precautions and to keep cool and hydrated on Monday and Tuesday.
The heat has prompted the UK's first red warning for extreme heat. The rise in temperatures has also forced the UK Health Security Agency to issue a level 4 heat-health alert – described as an “emergency”.
Britons are being urged to stay inside during the hottest points of the day, between 11am and 4pm, and wear sun cream, a hat, stay in the shade and keep hydrated with water. Some schools in several counties, including Nottinghamshire and Hampshire, have confirmed they will close, while train companies urged people not to travel on Monday and Tuesday.
