Snow expected in the Alpine massifs
This meteorological episode occurs in an overall rainy context for several weeks. Consequently, “the soils are already saturated with water”recalls Météo-France, with risks of a “reaction of watercourses” and of “mudslides, even landslides locally”.
Snow is expected in the Alpine massifs for the day. While the rain-snow limit will drop in the afternoon, going from 2200 to 2300 meters above sea level to 1100 meters to 1500 meters, two to four centimeters are expected on average in the massifs: “Locally, we could reach 50 to 60 mm on the Mont Blanc massif”specifies Météo-France.
