Fresh wind slabs represent the main danger. Weak layers in the lower part of the snowpack necessitate caution.
The fresh wind slabs are in some cases prone to triggering on northwest to north to southeast facing aspects above the tree line. Single winter sport participants can release avalanches as before, including medium-sized ones. The avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain. At elevated altitudes the avalanche prone locations are present in all aspects. Shooting cracks when stepping on the snowpack can indicate the danger. Avalanches can in isolated cases be triggered in near-ground layers. Caution is to be exercised in particular on very steep northwest, north and east facing slopes above approximately 2200 m. As a consequence of warming during the day and solar radiation mostly small loose snow avalanches are to be expected. This applies on extremely steep sunny slopes.
10 to 20 cm of snow fell on Friday. As a consequence of a storm force wind from northwesterly directions, avalanche prone wind slabs formed. They are lying on the unfavourable surface of an old snowpack in particular on northwest to north to southeast facing aspects. The new snow and wind slabs are lying on a crust on steep sunny slopes and generally at intermediate and high altitudes. The snowpack will be in some cases subject to considerable local variations.
Increase in avalanche danger as a consequence of new snow and strong wind. Fresh wind slabs represent the main danger. Weak layers in the old snowpack necessitate caution.
