“The high-altitude depression at the origin of the stormy deterioration is currently moving up over Spain towards the Pyrenees”said Météo France on Saturday morning.
In Aquitaine, “frequent thunderstorms are present” accompanied by a “strong electrical activity, locally high rainfall intensities sometimes of 20 to 30 mm/h” and of “hail in places”.
High temperatures across the country
From the Massif Central to the northeast, the stormy episode has not yet begun. In the morningthese storms will extend to the Centre-Val de Loire, while from the Pays de Loire to the Ile-de-France, Champagne-Ardenne and Lorraine, the cloudy passages could give locally stormy but more isolated showers.
Likewise, from Occitanie to Provence-Alpes-Côte d’Azur, the sky will be very cloudy and a few showers will be possible from the morning. But at the same time, a more marked stormy degradation will approach the Pyrenees, and will quickly extend towards the Massif Central.
The afternoonfrom the east of the Pyrenees to Limousin, then to Auvergne Rhône-Alpes, storms will become strong and multiply, giving high intensities of rain, sometimes hail and powerful gusts of wind.
This area of storms will head towards the Centre-Val de Loire, the east of the Ile-de-France and Bourgogne Franche-Comté at the end of the afternoon, to reach the Grand-Est in the evening, with continued heavy rain, violent gusts of wind and hail, particularly in the north-east of the country where these storms will be the most violent.
Only the regions from Brittany to Nord-Pas-de-Calais, as well as Corsica, will remain safe from this bad weather, and will keep a calmer but cloudy weather. The south-easterly wind will blow quite strongly until the beginning of the afternoon from Provence-Alpes-Côte d’Azur to the Massif Central.
Morning temperatures will be between 8 and 13 degrees from Brittany to Belgium, from 15 to 20°C elsewhere, up to 21 to 22°C in Corsica. The afternoonit will be 18 to 23°C near the Channel and the Atlantic, 23 to 28°C elsewhere, but up to 27 to 32°C from the Grand-Est to Berry, Rhône-Alpes and Provence-Alpes-Côte d’Azur, and in Corsica, locally 34°C in the Alsace plain and on the Isle of Beauty.
