Storms, hail and wind
But the weather deteriorated gradually, especially in the Pyrenees, where isolated but locally stormy showers watered the soil at the end of the day. Little by little, the weather will become more and more threatening in the south of New Aquitaine. Sometimes strong thunderstorms, with a risk of hail and gusts of wind, will break out and spread across the entire Atlantic coast in the evening.
At 4 p.m., Météo-France placed 46 departments, including the entire West, from north to south, on yellow storm vigilance.

Sunday, the sky will still be very disturbed in the Southwest with, on the program, clouds and stormy showers. Storms can sometimes be strong, accompanied by hail, and with gusts blowing up to 80/90 km/h, even very locally 100 km/h. However, the heat will persist with temperatures still close to 30°C.

A heat dome
And this mildness should last, at least until the middle of next week, with temperatures up to 32 or even 33 ° C in the South. According to La Chaîne Météo, the temperatures felt might even exceed 40 ° C at the height of the day, as in Charente-Maritime, Wednesday.
The nights will also be very mild with, from Monday, minimums often between 15 to 19°C, or even 20°C in the south. Seasonal averages are generally between 8 and 14°C.
This heat is explained by the presence of a hot air dome which extends from the Iberian Peninsula to central Europe via France, explains Meteo-France who adds: “This is an episode of heat remarkable for its precocity, its durability and its geographical extent. […] Without being exceptional, an episode of heat like the one expected next week, early and lasting, is still not so frequent. »
