Stability: very poor · Frequency: many
A precarious avalanche situation will prevail.
Avalanches can be released in the weakly bonded old snow, even by a single winter sport participant. This applies in particular on west, north and east facing slopes above the tree line. Mostly avalanches are medium-sized. Remotely triggered avalanches are possible in isolated cases. The avalanche prone locations are widespread and are barely recognisable. Individual avalanche prone locations are to be found also in areas close to the tree line. 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. Caution and restraint are required.
In some regions up to 50 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 above the tree line. The old snowpack is faceted. This applies especially in shady places that are protected from the wind.
Caution and restraint are required.
