A significant stormy degradation concerns 3/4 of the country this weekend, until Monday, hence our special press release. This situation is linked to the fact that France is stuck in the heart of a conflict of air masses, between very hot air which rises from the Maghreb towards the center of Europe and fresh air from Atlantic origin. This situation is conducive to violent phenomena.
This Saturday at 12 noon , rain and storm activity is spreading to the entire Atlantic coast. Between Lorient and Biarritz, the thunderstorm is raging and showers are sometimes mixed with hail from time to time. These rains, showers and thunderstorms spread inland rapidly.
At 11 am, the entire Atlantic arc is affected by the arrival of the ocean disturbance with the increase in rains and thunderstorms. In the east, the heat is rapidly increasing and 30 ° C are already approached in the Alsace plain and 28 ° C in the Saône valley in Lyonnais. The atmosphere is particularly heavy with a feeling of 35 over Strasbourg and Colmar.
At 10 am , the thunderstorms which had come up from the Aquitaine basin last night in Center-Val de Loire in the early morning ceased. The sky has nevertheless charged over the Paris basin where a few drops are reported.
But already, a new stormy degradation is taking place on the Bay of Biscay and approaches the Aquitaine coast by 11 hours.
At 9 a.m., thunderstorms broke out in the southwest and are currently reaching the Center-Val de Loire. It was in Gironde that the thunderstorms were strongest last night.
The city of Bordeaux suffered the passage of a very violent storm with 40 mm of rain recorded between 1 and 3 am, which corresponds to 2 to 3 weeks of rain that fell in just 1 hour! Other violent storms affected locally Charente-Maritime and Loire-Atlantique.
In this mid-morning, a few thunderstorms burst in the Loiret before going up towards Seine-et-Marne and Eure-et-Loir. The weather will then become fairly calm until the end of the morning, before the outbreak of new fairly organized thunderstorms from the south of Morbihan to the Vendée coast as well as over the Pyrenees mountains.
