An Amber Extreme heat warning, which is an impact-based warning designed to highlight impacts to protect lives, property and infrastructure, has been issued for Sunday, Monday and Tuesday.
Temperatures are likely to peak in excess of 35°C in southern, central and eastern areas of England, and more widely around 32°C within the warning area.
Tuesday currently looks to see the peak of this heat, although exceptional warmth is likely throughout the warning period.
Dr Agostinho Sousa, head of Extreme Events and Health Protection at UKHSA, said: “Heat-health alerts have now been issued to the majority of the country, with temperatures set to remain consistently high throughout the duration of this week.
“Most of us can enjoy the hot weather when it arrives, but it is important to keep yourself hydrated and to find shade where possible when UV rays are strongest, between 11am and 3pm.
“If you have vulnerable family, friends and neighbours, make sure they are aware of how they can keep themselves protected from the warm weather.’’
Mel Clarke, customer service director for Operations at National Highways, said: “It is always important to plan ahead for your journey and this advice is no different during periods of hot weather.”
