The departments at risk for heavy rains are: Alpes-Maritimes, Var, Bouches-du-Rhône, Gard, Alpes-de-Haute-Provence, Hautes-Alpes, Vaucluse, Lozère, Aveyron and Pyrénées-Atlantiques.
Winds of up to 80 kilometers per hour are expected to blow to the southwest, with violent waves expected along the Atlantic coast from Spain and around Brittany to the Channel coast of Normandy.
The departments on alert for the storms are: Hérault, Aude, Tarn, Ariège, Garonne, Tarn-et-Garonne, Lot-et-Garonne, Gers, Haute-Pyrenees, Pyrenees-Atlantique, Landes, Gironde, Charente-Maritime and Finistère.
Flooding in Pas-de-Calais and Finistère
A wave of wet weather is expected to worsen the situation in the Pas-de-Calais region, where the Canche River has already been flooded for a week.
In Finistère, the Laeta River was subjected to tidal flooding, which was exacerbated by strong winds.
Other departments on alert for possible flooding are: Vosges, Moselle, Meuse, Marne, Ardennes, Aisne, Nord, Oise, Seine-Maritime, Eure, Ile-Villain, Vendée, Deux-Sèvres, Charente-Maritime, Charente-Lands, Pyrenees-Atlantic, Ardèche, Gard, Drome, Vaucluse, and Alpes-Maritimes.
The weather event that brings a corridor of wet weather from the Caribbean into France is known as the “Rum Express.” A similar phenomenon is hitting California known there as the “Pineapple Express.”
“The phenomenon is due to successive air depressions over the Atlantic Ocean, which rotate simultaneously, like pumps, sending hot and humid air north,” Meteo France reported.
The “Rum Express” is expected to reach its peak on Saturday morning and lose intensity by Sunday.
