The late summer heatwave is about to end. After a new episode of hot weather at the start of September, temperatures will begin to drop on Monday September 11. Île-de-France, Eure-et-Loir, Loiret, Loir-et-Cher, Cher, Indre and Indre-et-Loire, which were on heatwave orange vigilance these three last few days, will see the alert lifted this Monday morning.

On the other hand, meteorologists continue to warn of the risk of storms, particularly in the western half of the country. “Sometimes strong thunderstorms (with hail, heavy rain, gusts) are expected on Monday in the departments currently placed on yellow alert (thunderstorms), from New Aquitaine to Hauts-de-France. A worsening of the level of vigilance cannot be ruled out in certain departments,” we can read in the Météo-France weather bulletin.

These thunderstorms will be strong at times, with a risk of small to medium hail and wind gusts between 60 and 80 km/h. At the end of the afternoon and in the evening, these storms will cross the Centre-Val de Loire then the Paris basin and reach the north of the country. An isolated thunderstorm risk will also persist further west, from Aquitaine to Brittany and Normandy.

Over the eastern half of the country, dry and sunny weather will dominate. The sky will gradually become cloudy from the west but will remain bright.

Minimum temperatures will range from 15 to 20 degrees in general.
