Stability: poor · Frequency: few
Weakly bonded old snow represents the main danger.
Avalanches can be released in the weakly bonded old snow by a single winter sport participant. This applies in particular on west, north and east facing slopes above approximately 1800 m. In some cases avalanches are medium-sized. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger. In the regions neighbouring those that are subject to danger level 3 (considerable) the avalanche danger is higher.
The new snow and wind slabs of the last few days are lying on top of a weakly bonded old snowpack on west to north to east facing aspects above approximately 1800 m. Distinct weak layers exist in the old snowpack. Outgoing longwave radiation during the night will be good at times.
The weather conditions will facilitate a very slow stabilisation of the snowpack.
