A precarious avalanche situation will be encountered over a wide area. Caution and restraint are required.
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 in isolated cases. 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.
The large quantity of fresh snow of last week and the extensive wind slabs are lying on top of a weakly bonded old snowpack above the tree line. The old snowpack is faceted. Distinct weak layers exist in the snowpack.
Avalanches can as before be released very easily. The snowpack remains prone to triggering.
