Stability: poor · Frequency: some
Wind slabs represent the main danger.
Over a wide area 10 to 20 cm of snow, and even more in some localities, has fallen above approximately 1000 m. The wind was strong. The new snow can be released naturally in all aspects above the tree line. The avalanche prone locations for dry avalanches are to be found especially at the base of rock walls and behind abrupt changes in the terrain. Mostly the avalanches in these loacations are small. The sometimes strong wind has transported some snow. In particular adjacent to ridgelines wind slabs formed. The sometimes deep wind slabs represent the main danger. They can be released even by a single winter sport participant above approximately 2000 m. In particular on very steep slopes and adjacent to ridgelines medium-sized slab avalanches are possible as a consequence of new snow and wind.
Towards its base, the snowpack is faceted and weak. The covering of new snow is soft. Above the tree line, shady slopes: Over a wide area new snow and wind slabs are lying on a weakly bonded old snowpack.
The avalanche conditions remain to some extent precarious.
