Stability: poor · Frequency: few
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.
The wind slabs are lying on top of a weakly bonded old snowpack. This applies especially on shady slopes above approximately 1800 m in places that are protected from the wind.
Weakly bonded old snow requires caution.
