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 very steep northwest, north and east facing slopes above the tree line. 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. In many places there is a danger of falling on the hard snow surface.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
Some snow will fall in some localities. The small quantity of fresh snow and the mostly small wind slabs that are forming during the snowfall will be deposited on the unfavourable surface of an old snowpack on shady slopes. 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 slight moistening of the snowpack in some cases, in particular at intermediate altitudes.

Winter sport participants can release avalanches now only rarely. The fresh wind slabs are to be evaluated with care and prudence in extreme terrain, especially on extremely steep shady slopes. Avalanches can in very isolated cases be released in the weakly bonded old snow 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. They are very rare but are difficult to recognise. In steep terrain there is a danger of falling on the hard snow surface.

Some snow will fall in some localities. The small quantity of fresh snow and the mostly small wind slabs that are forming during the snowfall will be deposited on the unfavourable surface of an old snowpack on shady slopes. In very isolated cases weak layers exist in the centre of the snowpack, in particular on steep shady slopes at high altitude. The weather conditions as the day progresses will give rise to slight moistening of the snowpack in some cases, in particular at intermediate altitudes.
Tendency
Low avalanche danger will persist. Fresh wind slabs require caution.
