Snowpack
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.

Wednesday
On Tuesday night a little more snow will fall in the north and east. The snowfall level will be approximately 1000 m. Once the residual cloud disperses, Wednesday will be quite sunny in the northeast as well.
The avalanche danger will decrease in the north, but not change significantly in the south.
Thursday
On Wednesday night a strong southwesterly wind will develop. Thursday will be quite sunny in the mountains.
In the north, the southwesterly wind will give rise to snow drift accumulations that are prone to triggering. The avalanche danger may increase a little in some regions. In the south it will not change significantly.
