WEATHER: Thunderstorms are expected from the west but it will still be very hot, according to Meteo France, which has placed 13 departments on Red Alert
Will they be the sign of a drop in temperatures? Local thunderstorms are expected this Wednesday morning on part of the western facade, between Vendée and Brittany. If the expected episode today will be brief (1 or 2 hours), Meteo France forecasts intense thunderstorms with hail, heavy rains, significant electrical activity and gusts that can locally exceed 100 km/h.
In total, thirteen departments in the north of the country remain in red alert for heatwave and thunderstorms and 60 departments of the South-West in the North-East are in orange vigilance. At the end of the morning, in the south of the Loire, the storm cells amplify and organize themselves into a denser system. This active and increasingly violent stormy body rises in the early afternoon over the Loire Valley then reaches Brittany and Maine, and in the late afternoon Lower Normandy.
In the early evening, the thunderclaps will be more and more numerous on a southwest quarter. Showers can be sustained. In the northeast, light thunderstorms will occur during the day. They will strengthen in the evening.
⛈ Nette dégradation orageuse par la façade ouest.
Forts #orages du nord de la Nouvelle Aquitaine à Normandie, puis jusqu’à la frontière belge l’ap-midi. Accompagnés de fortes rafales, risque de grêle.
