Stability: poor · Frequency: many
The current avalanche situation calls for caution and restraint. The new snow and wind slabs remain prone to triggering. Slight increase in avalanche danger as a consequence of new snow and wind.
Wind slabs and weakly bonded old snow represent the main danger.
The fresh snow and the wind slabs formed during the snowfall are lying on top of a weakly bonded old snowpack on west, north and east facing slopes above approximately 2000 m. Especially here avalanches can be triggered in the faceted old snow. This applies even in case of a small load. Mostly avalanches are medium-sized. Remotely triggered avalanches are possible in isolated cases. The avalanche prone locations are covered with new snow and are barely recognisable. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. Isolated loose snow avalanches are possible as a consequence of warming during the day and solar radiation, in particular on very steep sunny slopes.
Up to 20 cm of snow, and even more in some localities, has fallen since Saturday. As a consequence of a moderate wind from southerly directions, soft wind slabs formed. These are lying on top of a weakly bonded old snowpack in particular on shady slopes above approximately 2000 m. The old snowpack is faceted and weak. This applies especially in shady places that are protected from the wind. The old snowpack will be subject to considerable local variations.
