At elevated altitudes a sometimes precarious avalanche situation will be encountered in some regions.
The strong wind has transported some snow. The new snow and wind slabs are lying on the unfavourable surface of an old snowpack in all aspects. These avalanche prone locations are to be found above the tree line and in gullies and bowls. Caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls. Even single backcountry tourers can release avalanches in some places, including medium-sized ones. Small and medium-sized natural avalanches are possible on very steep slopes, in particular in the regions with a lot of snow. Mostly avalanches are medium-sized. Experience in the assessment of avalanche danger is required. On steep grassy slopes more small and, in isolated cases, medium-sized gliding avalanches are possible.
Over a wide area 20 to 40 cm of snow, and even more in some localities, has fallen above approximately 2000 m. The sometimes strong wind has transported a lot of snow. The new snow and wind slabs of the last few days are lying on the unfavourable surface of an old snowpack in all aspects above the tree line, in particular in places that are protected from the wind. These weather conditions fostered a weakening of the snowpack in particular on very steep slopes. The snowpack will be subject to considerable local variations. Snow depths vary greatly above the tree line, depending on the infuence of the wind. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack confirm the unfavourable bonding of the snowpack.
Fresh wind slabs represent the main danger.
