Wind slabs and weakly bonded old snow require caution.

Wind slabs and weakly bonded old snow require caution.

Weak layers in the old snowpack can be released by winter sport participants on very steep west, north and northeast facing slopes. The avalanche prone locations are to be found in particular on little used shady slopes above approximately 2000 m and on very steep west facing slopes above approximately 2300 m. Mostly the avalanches are medium-sized. Individual medium-sized natural avalanches are possible. Caution is to be exercised in particular in the regions exposed to heavier precipitation. As a consequence of a moderate to strong wind from southwesterly directions, avalanche prone wind slabs formed in the last few days. The number and size of avalanche prone locations will increase with altitude. Individual dry loose snow avalanches are possible. In the event of prolonged bright spells this applies on extremely steep slopes. On steep grassy slopes individual small and, in isolated cases, medium-sized gliding avalanches are possible.

10 to 30 cm of snow, and even more in some localities, has fallen since Wednesday. 10 to 20 cm of snow, and even more in some localities, will fall on Friday. This applies at high altitudes and in high Alpine regions. The wind will transport the new snow. Weak layers exist in the centre of the old snowpack in particular on little used shady slopes. Faceted weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. The various wind slabs are lying on soft layers at elevated altitudes. The old snowpack will be moist at low and intermediate altitudes. Only a small amount of snow is lying for the time of year.

Wind slabs and weakly bonded old snow require caution. Up to 10 cm of snow, and even more in some localities, will fall.
