New snow and weakly bonded old snow represent the main danger.
The large quantity of fresh snow as well as the extensive wind slabs that are forming over a wide area can be released easily or naturally above approximately 2200 m. Additionally avalanches can also release deeper layers of the snowpack and reach large size. This applies in particular on steep, little used shady slopes above approximately 2200 m, as well as on steep, little used west and east facing slopes above approximately 2600 m. Remotely triggered and natural avalanches are to be expected. Gliding avalanches are also to be expected at any time. This applies on grassy slopes below approximately 2400 m, in the regions exposed to a lot of precipitation especially.
30 to 50 cm of snow has fallen since Saturday, in particular at high altitudes and in high Alpine regions. 50 to 70 cm of snow, and even more in some localities, will fall until Tuesday. The fresh snow and the extensive wind slabs formed during the snowfall are lying on soft layers in all aspects above approximately 2000 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.
Gradual decrease in avalanche danger.
