The fresh wind slabs can be released easily. or in isolated cases naturally, in all aspects. Avalanches can reach medium size. Avalanches can also be released in near-ground layers. The avalanche prone locations are to be found especially on shady slopes above approximately 2000 m and on rather lightly snow-covered sunny slopes above approximately 2400 m. Especially transitions from a shallow to a deep snowpack are unfavourable.
The wind slabs are to be avoided in steep terrain.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
Up to 20 cm of snow will fall. The sometimes storm force wind will transport the new snow significantly. The fresh wind slabs will be deposited on the unfavourable surface of an old snowpack above approximately 2000 m. Avalanche prone weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. This applies in particular above approximately 2000 m.
Tendency
Wind slabs are to be evaluated with care and prudence.

Individual avalanche prone locations are to be found on very steep northwest, north and northeast facing slopes at elevated altitudes.
Avalanches can in very isolated cases be released by small loads and reach medium size. This applies in particular above approximately 1900 m on very steep northwest, north and northeast facing slopes. Caution is to be exercised at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example.
As the day progresses the likelihood of wet snow slides being released will increase below approximately 1900 m.

Some snow will fall.
Above approximately 1900 m: Weak layers exist in the bottom section of the snowpack on northeast, north and northwest facing slopes.
Below approximately 1900 m and steep sunny slopes: The old snowpack will be moist.
As a consequence of the sometimes strong wind the previously small wind slabs will increase in size as the day progresses. The near-surface layers of the snowpack can be released even by individual winter sport participants in particular on northeast, north and east facing slopes. Avalanches can also be triggered in near-ground layers and reach medium size. The avalanche prone locations are to be found in particular above approximately 2000 m.
As a consequence of warming during the day and solar radiation individual moist loose snow avalanches are possible. This applies on extremely steep slopes.

10 to 25 cm of snow has fallen. The strong wind will transport the new snow. The fresh wind slabs are lying on the unfavourable surface of an old snowpack.
West, north and east facing slopes above approximately 2000 m: Avalanche prone weak layers exist in the bottom section of the old snowpack.
Below approximately 2000 m: The old snowpack will be moist.
Tendency
Wind slabs and weakly bonded old snow require caution.

Avalanches can in isolated cases be released in the old snowpack and reach medium size. The avalanche prone locations are to be found in particular on very steep west, north and east facing slopes above approximately 2000 m. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example.
In addition the small wind slabs are prone to triggering in isolated cases, in particular in gullies and bowls, and behind abrupt changes in the terrain on very steep shady slopes at elevated altitudes. These can in isolated cases be released by people.

Some snow has fallen in some regions. The fresh wind slabs are lying on the unfavourable surface of an old snowpack in particular on shady slopes at elevated altitudes.
Above approximately 2000 m: Avalanche prone weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. Towards its surface, the snowpack consists of faceted crystals. This applies on shady slopes.
Below approximately 2000 m and steep sunny slopes: The old snowpack will be moist.

Low avalanche danger will prevail.
Dry avalanches can be released in near-ground layers, in particular by large additional loads. This applies in particular on northwest, north and northeast facing slopes above approximately 1900 m in steep rocky terrain. The avalanche prone locations are rare but are barely recognisable. In very isolated cases avalanches are medium-sized.
As the day progresses the likelihood of wet snow slides being released will increase below approximately 1900 m.
