Mediterranean episode: orange vigilance for Ardèche, Gard and Hérault

A Mediterranean episode is taking place. After Lozère, Gard and Hérault, Ardèche is in turn placed on orange alert due to a risk of rain, floods and storms, Météo-France announced on Tuesday, September 29, at 4 p.m. This vigilance will be active during the night from Tuesday to Wednesday. Météo-France warns that the “storms and heavy rainfall” will first fall on the Cévennes, “extending to the plains, allowing us to speak of a Mediterranean episode”.

Gard and Hérault are placed on orange “flood” alert from Tuesday afternoon. “In the Cévennes, if the rainy episode marked as orange alert is more intense and/or more lasting than expected, the accumulations could cause a move to the 'red' alert level,” specifies Météo-France. Accumulated rain in the plains could reach 50 to 80 mm possible in one hour. The accumulations over the episode will be around 200/300 mm, or even locally 350 mm.
