A dangerous avalanche situation will be encountered over a wide area. The danger exists in particular in alpine snow sports terrain.
Avalanches can be released in the weakly bonded old snow very easily. This applies in particular on west, north and east facing slopes above the tree line, in isolated cases also on south facing slopes above approximately 2200 m. Avalanches can reach large size. Remotely triggered avalanches are probable. The avalanche prone locations are widespread and are barely recognisable. The number and size of avalanche prone locations will increase with altitude. Fresh avalanches and whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. Great caution and restraint are required.
In some regions up to 80 cm of snow, and even more in some localities, has fallen since Saturday. The new snow and wind slabs are lying on top of a weakly bonded old snowpack. The old snowpack is faceted. This applies especially in shady places that are protected from the wind.
Avalanches can as before be released very easily. The snowpack remains prone to triggering over a wide area.
