Fresh wind slabs require caution.

Fresh wind slabs require caution.

As a consequence of a strong to storm force westerly wind, sometimes avalanche prone wind slabs will form. These avalanche prone locations are to be found in particular on northwest to north to east facing aspects above approximately 2200 m, especially on very steep slopes. At elevated altitudes the avalanche prone locations are more prevalent. Avalanches can additionally in very isolated cases be released in near-ground layers at high altitude. These avalanche prone locations are to be found in particular on very steep shady slopes and at transitions from a shallow to a deep snowpack. Caution is to be exercised in particular adjacent to ridgelines. They are very rare but are difficult to recognise.

Some snow will fall in some regions. In the west 20 cm of snow, and even more in some localities, will fall. The fresh wind slabs are lying on surface hoar in some places in particular on shady slopes above approximately 2200 m. In very isolated cases weak layers exist in the old snowpack, in particular on shady slopes at high altitude in areas where the snow cover is rather shallow. The weather conditions as the day progresses will give rise to moistening of the snowpack, in particular at intermediate and high altitudes.

Fresh wind slabs require caution. More frequent mostly small loose snow avalanches are to be expected.
