Wind slab
- Above 2,000 m
As a consequence of new snow and a storm force wind, sometimes avalanche prone wind slabs will form. Weakly bonded old snow is to be evaluated with care and prudence.

As a consequence of new snow and a gathering storm force wind from northwesterly directions, sometimes avalanche prone wind slabs will form. From early morning the wind slabs will increase in size additionally. The avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain above approximately 2000 m. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. Avalanches can reach medium size. Dry avalanches can additionally in isolated cases be released in the weakly bonded old snow also, especially on very steep shady slopes above approximately 2400 m. Avalanches can penetrate even deep layers and reach medium size. Caution is to be exercised in particular on extremely steep northeast facing slopes.
10 to 20 cm of snow will fall. The wind will be strong to storm force over a wide area. The weather will be cold. As a consequence of new snow and northwesterly wind, brittle wind slabs will form. The various wind slabs have bonded insufficiently together. Faceted weak layers exist in the old snowpack, especially on northwest, north and northeast facing slopes above approximately 2400 m. All aspects below approximately 2400 m: The old snowpack will be wet all the way through over a wide area. As a consequence of low temperatures the snowpack will consolidate. At low and intermediate altitudes from a snow sport perspective, in most cases insufficient snow is lying.
The danger of dry slab avalanches will persist. Some snow will fall on Tuesday in some regions, this applies in particular until the early morning. The wind will be strong in some regions.
