Weak layers in the old snowpack represent the main danger.
Dry slab avalanches are possible. Sometimes the avalanches are medium-sized and can be released in some cases even by a single winter sport participant. Avalanches can be released in near-ground layers by small loads. In addition the fresh and older wind slabs must be taken into account. In isolated cases the avalanches are large. Whumpfing sounds serve as an alarm indicating the danger.
In some cases new snow and wind slabs are lying 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.
