The Met Office has issued its first ever extreme heat warning for the UK with temperatures possibly reaching 33C in western areas.
The amber warning is in place for much of Wales, all of south-west England and parts of southern and central England.
“Many areas will continue to reach heatwave thresholds but the amber extreme heat warning focuses on western areas where the most unusually high temperatures are likely to persist,” said the Met Office’s chief operational meteorologist, Steven Ramsdale.
The warning is the first under the Met Office’s new extreme heat warning service launched in June.
