Wind slabs and weakly bonded old snow represent the main danger.
As a consequence of new snow and a sometimes strong 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 approximately 2200 m. As a consequence of warming during the day and solar radiation more frequent loose snow avalanches are to be expected. This applies in particular on rocky sunny slopes. Weak layers in the upper part of the snowpack can be released by individual winter sport participants. The 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. Mostly avalanches are medium-sized. Gliding avalanches can also occur. This applies on grassy slopes below approximately 2400 m, in the regions exposed to a lot of precipitation especially. Restraint is advisable on this first sunny day.
20 to 30 cm of snow, and even more in some localities, fell in the past few hours. In some localities up to 20 cm of snow will fall until the early morning. The fresh snow and the small wind slabs formed during the snowfall are lying on soft layers in all aspects above approximately 2200 m. West, south and east facing slopes below approximately 2400 m: The new snow is lying on a crust. 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.
The avalanche danger will increase but remain within the current danger level.
