Despite thunderstorms that have softened the temperatures, especially in the Paris Basin, 15 departments are still suffering from high temperatures on Monday.
The heatwave episode of the last few days continues this Monday, June 20 and until Tuesday from the center to the east of the country. The Weather Channel * places 15 departments on orange alert, namely Charente, Charente-Maritime, Corrèze, Creuse, Dordogne, Gers, Gironde, Indre, Indre-et-Loire, Landes, Lot, Lot-et-Garonne, Tarn-et-Garonne, Vienne and Haute-Vienne.
Temperatures will once again be exceptionally high, with records ranging from 35° to 38°C during the day and up to between 18° and 25°C at night. Alongside this strong heat, very strong thunderstorms sometimes accompanied by hailstorms will develop this Monday evening, from Aquitaine to Limousin.
The night from Sunday to Monday was overwhelmingly hot in the Center-East, where it was, for example, 26°C in Lyon Bron and Saint-Etienne. High temperatures also continue this afternoon, ranging from 32° to 36° C in the departments on yellow alert. In the night from Monday to Tuesday, expect tropical heat, with minimums above 20°C in the countryside and in large cities.
Monday evening, very violent storms are expected in the Southwest, between Landes and Limousin, via Gironde and Périgord. Strong thunderstorms will also break out in the early evening over the Aquitaine basin, as well as over the Pays de la Loire. Locally, accumulations of 50 mm of water are possible, accompanied by strong gusts of wind (>90 km/h) and a risk of hail. These weather conditions will progress towards the Centre-Val de Loire and will continue overnight from Monday to Tuesday, but will gradually ease at the end of the night.
