Danger level

Fresh wind slabs require caution. Individual weak layers exist in the old snowpack.
As a consequence of the moderate to strong northeasterly wind, fresh snow drift accumulations will form on Monday. These are mostly rather small but can be released easily. Avalanches can in some places be released, even by a single winter sport participant and reach medium size. Caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls above the tree line.
In isolated cases avalanches can be triggered in the faceted old snow and reach medium size in some cases. This applies in particular on very steep shady slopes above approximately 2300 m, as well as at transitions from a shallow to a deep snowpack.
Snowpack
dp.6: cold, loose snow and wind
dp.1: deep persistent weak layer
The old snowpack is faceted; its surface consists of loosely bonded snow. The moderate wind will transport the loosely bonded old snow. The brittle wind slabs will be deposited on the unfavourable surface of an old snowpack. As a consequence of low temperatures the snowpack can not consolidate. Faceted weak layers exist in the bottom section of the snowpack at high altitudes and in high Alpine regions.
Tendency
The avalanche danger will persist. The brittle wind slabs are bonding only slowly with the old snowpack.
