Fresh wind slabs require caution. Weakly bonded old snow above approximately 2200 m.
The new snow and wind slabs of the last few days can be released by a single winter sport participant. Avalanches can reach medium size. The avalanche prone locations are to be found in all aspects above the tree line. Additionally avalanches can also be released in the old snowpack. These avalanche prone locations are to be found on steep, little used shady slopes above approximately 2200 m and on steep sunny slopes above approximately 2500 m. They are sometimes covered with new snow and are difficult to recognise. Meticulous route selection is advisable.
Over a wide area 5 to 15 cm of snow has fallen since Sunday. The fresh snow and the wind slabs formed by the sometimes strong wind are lying on the unfavourable surface of an old snowpack. In some cases the wind slabs have bonded poorly with each other and the old snowpack. Faceted weak layers exist in the old snowpack, especially on shady slopes above approximately 2200 m, as well as on sunny slopes above approximately 2500 m.
The avalanche danger will persist.
