Météo France has placed Deux-Sèvres, Pas-de-Calais and Gironde on orange flood alert for Monday.
A depression circulating over France will be accompanied by a strong north to northeast wind along the Channel coast, and a strong north wind on the Atlantic coast.
A new rainy day is expected over a large part of the country for Monday, while three western departments, Deux-Sèvres, Pas-de-Calais and Gironde, are placed on orange flood alert, according to forecasts from Météo France.
The weather operator thus forecasts significant flooding on the Sèvre-Niortaise in Deux-Sèvres and the Canche in Pas-de-Calais, and overflows at the Garonne-Dordogne confluence in Gironde during high tides.

A strong north to northeast wind along the Channel coast
A depression circulating over France will be accompanied by a strong north to northeast wind along the Channel coast, and a strong north wind on the Atlantic coast.
The associated strong waves could cause submersion by crossing sea waves on exposed areas of the Channel coast and erosion on the coast of the Bay of Biscay, the weather operator further indicates.
However, it seems, it is stated, that the level of yellow vigilance is sufficient and a worsening of the level of vigilance thus becomes very unlikely for the wave-submersion phenomenon.
Particular attention will however need to be paid around the Arcachon basin where the flow of heavy rain this Sunday may be thwarted by high sea levels at high tide.
