The snow sport conditions outside marked and open pistes are critical.
In particular on west, north and east facing slopes more frequent medium-sized and, in isolated cases, large natural avalanches are possible during the first half of the night. In the regions exposed to heavier precipitation this applies especially. Avalanches can in many places be released in the old snowpack. The danger exists in particular in alpine snow sports terrain. Natural avalanches and whumpfing sounds are a clear indication of a weakly bonded snowpack. Remotely triggered avalanches are probable. The avalanche prone locations are prevalent and are barely recognisable.
10 to 25 cm of snow has fallen since Tuesday. 20 to 40 cm of snow, and even more in some localities, will fall. The new snow will be deposited on a weakly bonded old snowpack. Distinct weak layers exist in the old snowpack.
The avalanche conditions remain precarious.
