The more recent wind slabs can be released by a single winter sport participant in all aspects above the tree line. Individual avalanche prone locations are to be found also in areas close to the tree line. Caution is to be exercised in gullies and bowls, and behind abrupt changes in the terrain. Mostly avalanches are medium-sized. Additionally avalanches can also be released in the old snowpack. Such 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.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
As a consequence of the strong wind the wind slabs have increased in size additionally on Saturday. The new snow and wind slabs are lying on top of a weakly bonded old snowpack, in particular in shady places that are protected from the wind. Faceted weak layers exist in the snowpack, especially on shady slopes above approximately 2200 m, as well as on sunny slopes above approximately 2500 m. Isolated whumpfing sounds indicate the existence of a weak snowack.
Tendency
Wind slabs remain prone to triggering. They are to be evaluated with care and prudence in particular in very steep terrain. The avalanche danger will decrease gradually.

Fresh wind slabs require caution.
As a consequence of a sometimes storm force wind from northerly directions, mostly small wind slabs formed in particular above the tree line. The fresh wind slabs can be released by a single winter sport participant in all aspects above the tree line. Caution is to be exercised adjacent to ridgelines, as well as in gullies and bowls, and behind abrupt changes in the terrain. Wind slabs are to be avoided especially in terrain where there is a danger of falling.
Snowpack
dp.6: cold, loose snow and wind
In the early morning the wind will be strong in some cases. The small wind slabs will be deposited on weak layers in particular on very steep shady slopes. Hardly any weak layers exist in the old snowpack.
Tendency
Fresh wind slabs are to be evaluated with care and prudence in particular in very steep terrain.
