For those venturing off piste a dangerous avalanche situation will be encountered over a wide area.
As a consequence of new snow and a storm force northerly wind, sometimes large wind slabs formed in all aspects. In addition further wind slabs will form. These can be released easily. or in isolated cases naturally, above the tree line. Individual avalanche prone locations are to be found in areas close to the tree line and below the tree line. Avalanches can be triggered in near-surface layers and reach large size in isolated cases. Additionally in some places avalanches can penetrate near-ground layers of the snowpack, especially on west, north and east facing slopes above approximately 2200 m. Remotely triggered avalanches are possible. The danger exists primarily in alpine snow sports terrain.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
25 to 50 cm of snow, and even more in some localities, has fallen. The wind was violent in some cases. On Friday the wind will be strong to storm force. The wind will transport the new snow significantly.
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 as before be released easily. Restraint is advisable on this first sunny day.

Additionally in some places avalanches can penetrate near-ground layers of the snowpack, especially on west, north and east facing slopes above approximately 2200 m. The danger exists primarily in alpine snow sports terrain. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger.
In addition dry loose snow avalanches are to be expected, in the event of solar radiation especially on extremely steep slopes.

Fresh wind slabs are to be evaluated with care and prudence.
Wind slabs are in some cases prone to triggering in all aspects above the tree line. These can be released in near-surface layers. Avalanches can in very isolated cases penetrate near-ground layers of the snowpack and reach medium size on west, north and east facing slopes. Individual natural avalanches are not ruled out.

5 to 15 cm of snow, and even more in some localities, has fallen. The wind will be storm force in some cases. The northwesterly wind will transport the new snow. Avalanche prone wind slabs will form.

Fresh wind slabs require caution.
The fresh wind slabs can be released easily by a single winter sport participant 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. Avalanches are medium-sized.
In 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 2200 m. Especially transitions from a shallow to a deep snowpack are unfavourable.

10 to 15 cm of snow has fallen. As a consequence of the gusty wind the wind slabs will increase in size additionally.
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.
