Where is it snowing?
The alert areas are the whole of France up to the Arlberg in the north and the south-eastern Alps from eastern Italy via Carinthia to Slovenia. There are hardly any core zones in the north, but in Savoy and the lower Valais it is likely to be at the upper end, while the amounts of fresh snow on the Arlberg are more likely to be at the lower end. In the south, the area is quite small with a core in the Julian Alps.
Snow line
In the north and west, the snow line quickly drops below 1000m, so that the full amounts should come from 1000-1200m. In the southeast, it will remain relatively high for a long time, so that the full amounts will not arrive there until 1900-2100m.
