Weakly bonded old snow above approximately 2000 m. Fresh wind slabs require caution.
Single winter sport participants can release avalanches. These can penetrate even deep layers and reach medium size. The avalanche prone locations are to be found in all aspects above approximately 2000 m. These places are difficult to recognise. Between approximately 2000 and 2400 m the avalanche prone locations are more prevalent. Whumpfing and hissing sounds can indicate the danger. Large dry slab avalanches are possible in isolated cases. This applies in particular on very steep shady slopes in high Alpine regions. Caution is to be exercised at transitions from a shallow to a deep snowpack. As a consequence of new snow and strong wind the wind slabs will increase in size once again. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls and on steep shady slopes.
Snowpack
dp.1: deep persistent weak layer dp.6: cold, loose snow and wind
10 to 20 cm of snow, and even more in some localities, will fall on Friday. This applies in particular in the west. Over a wide area strong westerly wind. Faceted weak layers exist in the bottom section of the snowpack at elevated altitudes. Faceted weak layers exist in the top section of the snowpack in all aspects. This applies especially between approximately 2000 and 2400 m. Fresh wind slabs are lying on soft layers in particular on shady slopes at elevated altitudes. The weather conditions gave rise to moistening of the snowpack below approximately 2000 m.
Tendency
The avalanche danger will persist. Wind slabs and weakly bonded old snow require caution.

Fresh wind slabs require caution.
As a consequence of new snow and a strong wind, sometimes avalanche prone wind slabs will form at elevated altitudes. These avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls and on steep shady slopes.
