A four-day “extreme heat” warning went into effect on Thursday in some areas of England and Wales due to the likelihood of another heatwave with temperatures expected to exceed 35 degrees Celsius and put a strain on water supplies and transportation infrastructure.
The Met Office stated that its amber warning, which is its second-severest after red, will persist until Sunday and warned that anyone who are susceptible to excessive heat may experience negative health impacts.
Temperatures are expected to peak at 35C (95 Fahrenheit) on Friday and may hit 36C in some places on Saturday.
Much of England and Wales, plus eastern parts of Northern Ireland and Scotland, are forecast to be “sunny and hot or very hot” on Thursday, the Met Office’s website showed.
The warning follows the driest July for England since 1935, when temperatures rose above 40C for the first time, turning a renewed spotlight to the impacts of climate change.
Other European nations have also faced a scorching heatwave in recent weeks with temperatures often exceeding 40C.
During July’s heatwave, Britain, which is less used to such high temperatures, faced power outages, damage to airport runways and rail tracks and dozens of blazes in London, where the fire brigade faced its busiest week since World War Two.
Britain’s environment minister George Eustice on Wednesday urged water companies to take precautions to protect water supplies and tackle the effects of the prolonged dry weather.
Several water companies have already imposed restrictions on water usage and supermarkets have limited sales of disposable barbecues that firefighters warn can set light to tinder-dry grass.
This week’s amber warning follows Britain’s first-ever red “Extreme Heat” warning in July.
