Ardèche, Bouches-du-Rhône, Drôme, Gard, Hérault and Vaucluse should in particular be affected by a "Mediterranean event", with a "high potential for rain" from 6 a.m. Wednesday, said the manager.
“There are still a lot of uncertainties about the intensity” but locally the precipitation could reach up to 100 mm per hour with a risk of stationary rains, “a potential that worries us”, underlined Marc Pontaud.
Deadly storms in Corsica
Another stormy sequence will cross the country from Tuesday afternoon from south-west to north-east, with locally up to 40 mm of rain and risks of hail and gusts of wind up to 80 km / h .
Nevertheless, there "is always uncertainty about the exact location of the phenomena", recalls Météo France.
France experienced a record summer of heat waves and disasters linked to global warming, including deadly thunderstorms on August 18 in Corsica, which killed five people.
Météo France had been criticized for having poorly anticipated the vigilance to be issued, which it explained.
