Fresh wind slabs at high altitude. Gliding avalanches and moist snow slides are possible.

Fresh wind slabs at high altitude. Gliding avalanches and moist snow slides are possible.

As a consequence of a sometimes strong wind from southerly directions, avalanche prone wind slabs will form. Caution is to be exercised in particular on very steep shady slopes adjacent to ridgelines and in gullies and bowls at high altitudes and in high Alpine regions. Moist loose snow avalanches are possible below approximately 2200 m. In the event of prolonged bright spells this applies on extremely steep slopes. Mostly the avalanches are small and can be released by a single winter sport participant. As a consequence of the moist air there will be an increase in the danger of gliding avalanches. Caution is to be exercised in particular on steep grassy slopes. Weak layers in the old snowpack can be released in very isolated cases. The avalanche prone locations are to be found in particular on extremely steep shady slopes above approximately 2400 m. Avalanches can reach medium size in isolated cases.

Up to 10 cm of snow, and even more in some localities, will fall. This applies at high altitudes and in high Alpine regions. The wind will transport the new snow and, in some cases, old snow as well. The fresh wind slabs are lying on soft layers on shady slopes at elevated altitudes. Outgoing longwave radiation during the night will be barely evident. The surface of the snowpack will soften during the day. This applies at low and intermediate altitudes. Faceted weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. Only a small amount of snow is lying for the time of year.

Fresh wind slabs represent the main danger. In some localities up to 10 cm of snow, and even more in some localities, will fall.
