Avalanche Activity

Fresh wind slabs: Increase in avalanche danger.

The fresh wind slabs can be released easily. or in isolated cases naturally, in all aspects. Avalanches can reach medium size. Avalanches can also be released in near-ground layers. The avalanche prone locations are to be found especially on shady slopes above approximately 2000 m and on rather lightly snow-covered sunny slopes above approximately 2400 m. Especially transitions from a shallow to a deep snowpack are unfavourable. The wind slabs are to be avoided in steep terrain.

Snowpack Structure

Up to 20 cm of snow will fall. The sometimes storm force wind will transport the new snow significantly. The fresh wind slabs will be deposited on the unfavourable surface of an old snowpack above approximately 2000 m. Avalanche prone weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. This applies in particular above approximately 2000 m.

Tendency

Wind slabs are to be evaluated with care and prudence.
