Stability: poor · Frequency: many
Weakly bonded old snow requires caution.
Distinct weak layers in the upper part of the snowpack can be released very easily. The avalanche prone locations are to be found in all aspects above the tree line. Caution is to be exercised in particular adjacent to ridgelines, as well as in gullies and bowls, and behind abrupt changes in the terrain. In isolated cases avalanches are medium-sized. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger. Remotely triggered avalanches are possible in isolated cases.
10 to 30 cm of snow fell in the last few days. Up to 10 cm of snow, and even more in some localities, will fall. The wind will be strong at times. Over a wide area new snow and wind slabs are lying on a weakly bonded old snowpack. The old snowpack is faceted.
The avalanche danger will persist.
