Weather: Gard and Hérault placed on orange rain-flood alert, “vortex phenomena” not excluded

The departments of Gard and Hérault will be placed on orange rain-flood alert on Monday from 2:00 p.m. by Météo-France, due to a Mediterranean episode causing heavy rain and hail. The forecaster anticipates rain in the morning, followed by “stronger storms” coming up from the Mediterranean in the afternoon.

The rains could reach a flow rate of 70 mm in less than an hour, accompanied by gusts of up to 80 km/h and hail, indicates Météo-France, which does not rule out “vortex phenomena”.

The Bouches-du-Rhône department, currently placed on yellow alert, could see its alert level raised depending on developments. Accumulations could reach 40 to 80 mm, or even 150 mm locally. This Mediterranean episode will continue until Tuesday, warns Météo-France.

It is linked to a cold drop named “Adam” in Spain, which is preparing for torrential rains on Monday after floods which have already claimed the life of a woman near Barcelona.

At the end of September, the first Cévennes episode of the season drowned Montpellier and its surroundings in downpours, causing costly damage.
