Weak layers in the old snowpack represent the main danger.
Over a wide area over a wide area 15 to 30 cm of snow, and even more in some localities, has fallen above approximately 1500 m. Dry slab avalanches are possible. Avalanches can be released in near-ground layers by small loads. Remotely triggered and natural avalanches are possible. Sometimes the avalanches are large. Whumpfing sounds serve as an alarm indicating the danger.
New snow and wind slabs are lying mostly on old snow containing large grains. The avalanche-prone wind slabs are lying on weak layers in particular on wind-protected shady slopes above approximately 1500 m. Avalanches can be released by small loads.
The natural avalanche activity will gradually decrease.
