Three departments are concerned: Bouches-du-Rhône, Gard and Vaucluse.
Météo France placed these departments on orange vigilance this Friday morning in the face of the storms expected in the south-west of France in particular.
In its bulletin published at 6 a.m., the weather organization depicts a “rainy-stormy episode requiring special vigilance because of its intensity”.
“Storms persist at the end of the night, from the southwest to the northwest of the country.
However, the storms expected in the three departments placed in orange vigilance have of course not yet developed at this time, ”also explains Météo France.
