Météo France has also extended red vigilance for “floods” to three departments: Morbihan and Loire-Atlantique were added to the Ille-et-Vilaine which is in the grip of intense rain and important floods Since the passage of the Eowyn storm last weekend. The Breton department has even observed unpublished floods with “exceptional levels observed on the Vilaine and the cuttlefish”.

In addition to red vigilance, four other departments are on orange alert for “floods”: Calvados, Orne, Mayenne, Maine-et-Loire.

The situation should not, or little, improve in the coming hours. New showers are expected this Tuesday in the northwest of the country, notably Brittany, “but the cumulative people should remain fairly low” and limit their impact on the floods prevents the Vigicrues agency. In Ille-et-Vilaine, water levels must “stabilize and orient themselves slightly downwards at the end of the day”, especially in the cuttlefish and the mid-median. But elsewhere, the propagation of the flood risks achieving the ugly downstream “exceptional levels […] From the night from Tuesday to Wednesday “. The floods continue to spread in Normandy and on the Pays de la Loire with the Orne and the Oudon, but the Meteorological Agency does not provide” significant aggravations “for Tuesday.

The floods reinforced by a new storm?

IVO depression could touch the northwest of France during Wednesday and bring “a new rainy episode” which “depending on the location of the strongest precipitation” could lead to “aggravation of certain current floods”. Red and orange vigilances active this Tuesday are currently maintained for the day of Wednesday January 29.
