Avalanche Activity

Wind slabs and weakly bonded old snow require caution. The avalanche danger in particular above the tree line is within the uppermost range of danger level 3 (considerable).

The fresh snow of the last few days as well as the wind slabs are lying on the unfavourable surface of an old snowpack. Caution is to be exercised in particular on steep west, north and east facing slopes above the tree line. Distinct weak layers in the lower part of the snowpack can be released even easily by individual winter sport participants. Avalanches can penetrate down to the ground and reach large size. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and natural avalanches serve as an alarm indicating the danger. The avalanche prone locations are prevalent and are difficult to recognise. Remotely triggered avalanches are possible.

Snowpack Structure

The new snow and wind slabs of the last few days are lying on the unfavourable surface of an old snowpack. Distinct weak layers exist in the old snowpack. This applies especially on west, north and east facing slopes. The snowpack remains prone to triggering. Night: In some localities 5 cm of snow will fall above approximately 1500 m. The snowpack will be moist at low altitude.

Tendency

The avalanche danger will persist. Above the tree line a treacherous avalanche situation will be encountered over a wide area.
