French authorities warned Thursday that a record pre-summer heat wave was progressing north from Spain, where firefighters are battling several wildfires, on the sixth day of sweltering temperatures.
The Météo France meteorological service warned that this is the earliest heat wave since 2005, exacerbating the drought caused by an unusually dry winter and spring.
High temperatures also aggravate the risk of forest fires, such as those registered in Spain, which has already experienced the hottest month of May since the beginning of this century.
Spain is now facing temperatures of up to 43 degrees Celsius with no relief expected before Sunday, according to weather service Aemet.

The increased use of air conditioning and fans forced France to import electricity from neighboring countries, operator RTE said on Thursday, when many nuclear reactors are out of service due to corrosion problems or maintenance.
The intense heat also reduced the flow of the rivers, for which some nuclear power plants have to reduce production because the water used for cooling the reactors is too hot to be returned to the water courses without endangering the flora and fauna. fauna.
Spain, Italy and other countries have recently limited the use of air conditioners to save energy and the French minister of the branch, Agnès Pannier-Runacher, told the France 2 network that she was studying a similar measure.
Météo France issued heat wave alerts on Thursday in the southern half of the country and in the west, and advanced that more departments will be affected in the coming days.
