The wind slabs can be released easily.

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.

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

The small wind slabs are lying on the unfavourable surface of an old snowpack 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.
