“Treat this heat wave like a storm,” says Jeremy Wilks of Euronews.

The UK Met Office has issued the first-ever red alert for extreme heat as temperatures continue to rise across Europe.

Temperatures are expected to hit 40 degrees Celsius for the first time since records began in some parts of the country soon.

A red alert has also been issued in Spain, with temperatures reaching 45.6°C in the southern region of Andalusia.

Euronews space, science and technology correspondent Jeremy Wilks says the current heatwave is leaving citizens of all ages vulnerable.

“Everyone needs to stay hydrated and stay out of the sun … almost treat this heatwave like a storm,” he said.

“Even for people in their 20s and 30s when it’s so hot outside and the temperature is approaching 40 degrees. [Celsius]it’s dangerous for the body.”

“This is a sign of things to come and there is no sign that it will get colder in the coming years,” he added.
