Partly heavy snowfall and strong wind will give rise to extensive snow drift accumulations on Monday night in particular. These can be released very easily. In the west and north in particular, natural avalanches are to be expected. From southern Valais through northern Ticino to Grisons, weak layers exist in the old snowpack. Here, avalanches can be released in deep layers of the snowpack and reach a large size.

In the morning precipitation arrived from the northwest. During the day it was mostly very cloudy on the northern flank of the Alps, but sometimes bright in the inneralpine regions.
