This forecast announces the arrival of snowfall in the territory on Thursday, November 21, in the wake of the Caetano depression.
Snow precipitation should extend along an axis going from Brittany-Normandy to the Burgundy-Franche-Comté region, with a rain-snow limit cutting France in two at Nantes.
