Snowpack
Westerly and northerly winds have caused widespread snowdrift accumulations at high altitudes in recent days. Some of these are still prone to triggering. With the mild temperatures and rain, the snowpack has become saturated this week at intermediate altitudes and, on sunny slopes, up to high altitudes. An often brittle crust has formed below about 2200 m on the surface of the snowpack.
Before the precipitation in mid-November, there was a cohesive old snowpack, especially above approximately 2800 m. This contains some weak layers of faceted crystals, especially on northern slopes. Isolated avalanches can also be triggered in old, near-ground snowpack.

Outlook until Monday, 2.12.2024
On Sunday it will be mostly sunny in the mountains and mild with a zero-degree level at 2800 m. The wind will change to the northwest and will be mostly light. On Monday, clouds will gather from the west and light precipitation from the northwest will set in during the afternoon. The snowfall level will be 2000 m. It will be mostly sunny in the south and partly sunny in inneralpine regions.
The risk of dry avalanches will decrease. Gliding avalanches and moist snow slides during the day will be possible on steep sunny slopes.
