Europe's record temperature of 48C could be beaten this weekend

Britain is basking in 31C heat, three people have died from heatstroke in Spain as the mercury reached the mid-40s, and a mountain glacier in Sweden has melted so much that its peak is no longer the country’s highest point.

Alex Burkill, a Met Office meteorologist, said that despite the cooler temperatures of recent days “it is not the end of the hot weather for the summer” as sunshine returns to most of the country.

A yellow severe warning for thunderstorms was in place for some parts of England and Scotland until 9pm on Friday.

The Met Office said: “Some flooding of a few homes and businesses is possible, leading to some damage to buildings or structures. There is a good chance driving conditions will be affected by spray, standing water and/or hail, leading to longer journey times by car and bus. Some short-term loss of power and other services is likely.”

Sun-drenched British holidaymakers are enjoying record temperatures on the continent during their summer breaks. Tourists are being urged to avoid the sun during the hottest part of the day and remember that children are particularly susceptible to the heat.

Eight places in Portugal broke local temperature records on Friday as a wave of heat from North Africa swept across the Iberian peninsula and officials predicted the scorching temperatures could get even worse over the weekend.

Temperatures built to around 45C (113 F) in many inland areas of Portugal, and were expected to peak at 47C (116.6F) in some places on Saturday. Large sections of Portugal are on red alert on the country’s civil protection agency’s danger scale.

The highest temperature recorded on Thursday, when the heat began to rise, was 45.2 C (113.4 F) near Abrantes, a town 150km (93 miles) north-east of the capital, Lisbon, the country’s weather agency IPMA said.

In Spain three men died of heatstroke. A middle-aged man in Barcelona was found collapsed on a street and taken to hospital where he later died. Two other men – a roadworker in his 40s and a 78-year-old pensioner – also died from heatstroke.
