A rain-stormy disturbance advances over northwestern France. At the front, the air mass is very hot and the maximum temperatures will be very high Friday in the afternoon from South-West to the Center-East and North-East, says Météo-France. In the afternoon, thunderstorms must develop from Burgundy to Champagne, the Ardennes and Lorraine. On the east of Midi-Pyrenees, this stormy evolution will be later, rather late afternoon. It will then move towards the Center-East and Alsace.
These thunderstorms will be accompanied locally by heavy hail, heavy rainfall and violent wind gusts of up to 100 km / h.
