Snowfall started over western and northwestern Alps on Wednesday evening at about 2500 meters, dropping to below 2000 meters by Monday morning.

It will be spreading across much of the northern and central Alps on Friday.
The snow limit will be as low as 1400-1600 m across the northwestern and northern Alps, about 1800-2000 m over the central Alps.
Southeastern Alps, as far southeast as the Julian Alps in Slovenia will also receive snow, above 2200m. In the case of intense snow showers, the snow limit will drop lower. Although the snow in October, in the heart of Autumn, may seem strange, we specify that for the Alps it is absolutely normal to see days of this type, where the sudden drops in temperature allow the snow to return.
