'National emergency' declared as rare extreme heat warning issued

A 'national emergency' has been declared ahead of soaring temperatures next week. Forecasters say 'exceptional, perhaps record-breaking' temperatures will hit the country, with some places forecast to reach 40C.

The level four alert, which has been increased from a level three warning, is in place between midnight on Monday (July 18) and midnight on Wednesday (July 20). Level four alerts are issued when "a heatwave is so severe and/or prolonged that its effects extend outside the health and social care system," the UKHSA says.

"At this level, illness and death may occur among the fit and healthy, and not just in high-risk groups." The alert reads: "Renewed hot or very hot conditions develop across the country during this coming weekend and into the new working week, peaking on Monday and Tuesday, with some exceptional temperatures possible in places. The hottest locations are likely to be in parts of central and eastern England."

It's vital for people to stay safe while the alert is in place and the Met Office has issued further guidance on the matter. They advise looking out for others, particularly "older people, young children and babies and those with underlying health conditions."

To keep cool, they recommend keeping curtains closed in rooms that face the sun, as well as drinking plenty of fluids and avoiding excess alcohol. The Met Office adds: "Be on the lookout for signs of heat related illness. Cool your skin with water, slow down and drink water. Call NHS 111 or in an emergency dial 999."

It comes as the national weather service issued its first 'extreme heat' weather warning covering much of England next week.
