Wind slabs and weakly bonded old snow represent the main danger.
As a consequence of new snow and a sometimes storm force wind from northerly directions, avalanche prone wind slabs formed since Saturday in particular adjacent to ridgelines and in gullies and bowls. These can be released by a single winter sport participant. Caution is to be exercised in particular on steep slopes above the tree line. Weak layers in the upper part of the snowpack can be released by individual winter sport participants. These avalanche prone locations are to be found in particular on steep, little used shady slopes above approximately 2200 m and on steep, little used west and east facing slopes above approximately 2600 m. In isolated cases avalanches can also release deeper layers of the snowpack. Mostly avalanches are medium-sized. Individual gliding avalanches can also occur. This applies on steep grassy slopes below approximately 2400 m.
In some regions up to 40 cm of snow has fallen. As a consequence of new snow and strong wind the wind slabs have increased in size additionally. The new snow and wind slabs are lying on soft layers in particular on steep shady slopes above approximately 2200 m. Avalanche prone weak layers exist in the old snowpack especially on little used west, north and east facing slopes. This applies on shady slopes above approximately 2200 m, as well as on west and east facing slopes above approximately 2600 m.
Gradual decrease in avalanche danger.
