Wind slabs and weakly bonded old snow require caution.
Wind slabs are prone to triggering in all aspects above approximately 1600 m. These can be released in near-surface layers. Avalanches can in isolated cases penetrate near-ground layers of the snowpack and reach medium size on west, north and east facing slopes.
As a consequence of solar radiation loose snow avalanches are possible. This applies in particular on very steep slopes in places that are protected from the wind.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
20 to 30 cm of snow, and even more in some localities, fell in the last few days. The northwesterly wind has transported the new snow and, in some cases, old snow as well. As a consequence of a gusty wind, easily released wind slabs formed.
The new snow and wind slabs are lying on the unfavourable surface of an old snowpack above approximately 1600 m. The old snowpack will be weakly bonded, especially on west, north and east facing slopes above approximately 1900 m.
Tendency
Avalanches can be released by a single winter sport participant.

Outside marked and open pistes an unfavourable avalanche situation will prevail.
The extensive wind slabs are very prone to triggering in all aspects above the tree line. These can be released in near-surface layers and reach medium size. Avalanches can also penetrate near-ground layers of the snowpack and reach large size on west, north and east facing slopes. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and fresh avalanches serve as an alarm indicating the danger.
As a consequence of solar radiation loose snow avalanches are possible. This applies in particular on very steep slopes in places that are protected from the wind.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
20 to 50 cm of snow fell in the last few days. The wind was violent in some cases. The northwesterly wind has transported the new snow and, in some cases, old snow as well. Extensive wind slabs formed.
The new snow and wind slabs are lying on the unfavourable surface of an old snowpack above the tree line. The old snowpack will be weakly bonded, especially on west, north and east facing slopes above approximately 2200 m, and on south facing slopes at elevated altitudes.
Tendency
Avalanches can be released easily.

Avalanches can in isolated cases penetrate near-ground layers of the snowpack, especially on very steep west, north and east facing slopes above approximately 2200 m, and on south facing slopes at elevated altitudes. Avalanches are medium-sized.
Snowpack

10 to 20 cm of snow fell in the last few days. The northwesterly wind has transported the fresh and old snow significantly. As a consequence of a gusty wind, avalanche prone wind slabs formed.
The new snow and wind slabs are lying on the unfavourable surface of an old snowpack above approximately 1800 m. The old snowpack will be weakly bonded, especially on west, north and east facing slopes above approximately 2200 m, and on south facing slopes at elevated altitudes.

Fresh wind slabs are to be avoided.
Wind slabs can be released by a single winter sport participant in some cases in all aspects above approximately 1800 m. Avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain. This also applies at a distance from ridgelines. In isolated cases avalanches are medium-sized.
In very isolated cases avalanches can also penetrate near-ground layers of the snowpack. Caution is to be exercised in particular on very steep west, north and east facing slopes above approximately 1900 m. Especially transitions from a shallow to a deep snowpack are unfavourable.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
In some regions 10 to 15 cm of snow fell in the last few days. The northwesterly wind has transported the fresh and old snow significantly. As a consequence of a gusty wind, sometimes avalanche prone wind slabs formed.
The new snow and wind slabs are lying on the unfavourable surface of an old snowpack above approximately 1800 m. The old snowpack will be weakly bonded, especially on west, north and east facing slopes above approximately 1900 m.
