Rain and strong wind in Hérault: why are we talking about a Cévennes episode?. The equivalent of three weeks to a month of rain is falling in the region in about 36 hours.
The region is also experiencing a fairly exceptional succession with a fifth occurrence since February. Concerning the current episode, accumulations of around 120 mm are expected. This level could locally be exceeded and reach 150 mm, that is to say 150 liters per square meter in 36 hours, says Météo France.
