A difference of a few tens of kilometers will be enough to switch between rain and snow”notes the forecaster.

“The regions most exposed to the risk of snow seem to stretch along an axis going from the south of Normandy to the Jura. It is still too early to indicate potential accumulations” Météo-Express rating on X.

This depression will be characterized by strong winds which will blow across the Atlantic coast. It is to the south of the depression that they will be strongest with gusts of 100 to 120 km/h on the Aquitaine coast and the heights of the Massif Central in the morning.
