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 2400 m. Avalanches can reach medium size. Individual natural avalanches are possible. Caution is to be exercised in particular in the regions exposed to heavier precipitation. As a consequence of new snow and a moderate to strong wind from southerly directions, further wind slabs will form on Saturday. The number and size of avalanche prone locations will increase with altitude. The avalanche prone locations are barely recognisable because of the poor visibility. Dry loose snow avalanches are to be expected, in the event of prolonged bright spells especially on extremely steep slopes. On steep grassy slopes individual small and, in isolated cases, medium-sized gliding avalanches are possible.

20 to 50 cm of snow, and even more in some localities, has fallen since Wednesday. 5 to 15 cm of snow, and up to 30 cm in some localities, will fall on Saturday. 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. They are prone to triggering in particular on west to north to northeast facing aspects. 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.
