Avalanches can as before be released, even by a single winter sport participant. The snowpack remains prone to triggering.
An unfavourable avalanche situation will be encountered over a wide area. The conditions are treacherous for backcountry touring.
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. Mostly avalanches are medium-sized. Remotely triggered avalanches are possible. The avalanche prone locations are widespread and are barely recognisable. The number and size of avalanche prone locations will increase with altitude. 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. The old snowpack is faceted. Distinct weak layers exist in the snowpack.
