Stability: poor · Frequency: few
The wind slabs are lying on top of a weakly bonded old snowpack. This applies especially on shady slopes above approximately 2200 m in places that are protected from the wind.
Weakly bonded old snow requires caution.
Weak layers in the old snowpack represent the main danger.
As a consequence of a moderate to strong wind from variable directions, wind slabs formed in the last few days. Avalanches can be released in near-ground layers in particular in gullies and bowls, and behind abrupt changes in the terrain. This applies even in case of a single winter sport participant. In steep gullies they can reach medium size. Shooting cracks when stepping on the snowpack can indicate the danger. The Avalanche Warning Service currently has only a small amount of information that has been collected in the field, so that the avalanche danger should be investigated especially thoroughly in the relevant locality.
