Europe Faces Intense Heatwave with Temperatures Exceeding 40C

Red heat alerts have been issued in France, Spain and other nations across western and central Europe as heatwave conditions are forecast to intensify in the coming days with highs of more than 40C.

More than half of France's regions are currently under the harshest weather warning, with hundreds of schools ordered to close and highs of 42C hitting Bordeaux on Monday, forecaster Météo-France said.

Two children aged two and four have been found dead in their family car in the town of Carpentras in the south of France, in an accident being linked to the weather.

Similar red warnings have been issued by the authorities in Germany, Italy, Switzerland and Luxembourg.

The rising temperatures are being driven by hot air moving north from the Sahara desert, which is in turn trapping hot air over the affected areas, with forecasters suggesting the conditions could result in one of the longest heatwaves in recent years.

Scientists have said that recurring heatwaves are a marker of global warming, with Météo-France noting that of the 51 heatwaves recorded in France since 1947, 34 have taken place since 2000 and 26 since 2011.

Elsewhere the conditions have seen:

Spain's state weather service Aemet warn of "extremely high" temperatures for the season until Wednesday "between five and 10 degrees above what is typical" - with some areas set to reach 44C.

Temperatures are expected to peak in many parts of the continent on Wednesday, with 41C forecast for Paris.

In the capital on Monday, several train lines also reduced services. France's national railway operator SNCF urged "vulnerable" people to avoid or postpone train travel this week.

Some 845 schools in France were shut, while a further 1,800 are allowing pupils to finish classes early, the education ministry said. But more than a million high school students were to take their oral final exams for the baccalaureate amid the heat.

A red heat alert is the highest of four warnings issued by Météo-France, and advises people to exercise extreme caution in conditions that are potentially life-threatening.

Dozens of other regions in France are under an orange alert - the second-highest warning - with an estimated 63 million people in total affected across the country.

The conditions in France follow a weekend in which the mercury hit 40C, prompting an alcohol ban at the annual Fête de la Musique, a national festival that sees large crowds celebrate on the streets of most cities.

The ban applied to all events organised by the French state and its agencies, and aimed "to preserve emergency and healthcare services and allow medical staff to focus on caring for the most vulnerable", the government said.

While the hottest temperatures are expected on the western coast, highs are expected to hang around 36C to 40C across much of the rest of the country, Météo-France said.

The forecaster warned that the heatwave will be "widespread, long-lasting and intense" - with temperatures not expected to drop until the end of the week.
