Avalanche Activity

During the course of the night as a consequence of new snow and strong wind there will be an increase in the avalanche danger to level 2 (moderate).

15 to 20 cm of snow will fall during the night above approximately 1400 m. As a consequence of new snow and a moderate to strong southeasterly wind, mostly small wind slabs will form during the course of the night above approximately 2200 m. They will be deposited on unfavourable layers on shady slopes. Such avalanche prone locations are to be found between approximately 2300 and 2800 m. The fresh snow and the wind slabs can be released by a single winter sport participant.

Snowpack Structure

During the night the wind will be moderate to strong. Sunny slopes: The surface of the snowpack has frozen to form a strong crust. The new snow and wind slabs will be deposited on a crust on steep sunny slopes. In shady places that are protected from the wind: Towards its surface, the snowpack is dry and has a loosely bonded surface. The new snow and wind slabs will be deposited on the unfavourable surface of an old snowpack on steep shady slopes above approximately 2300 m. Snow depths vary greatly above approximately 2200 m, depending on the infuence of the wind. Adjacent to ridgelines and in pass areas and at high altitude a little snow is lying. At low altitude less snow than usual is lying. Below approximately 2200 m no snow is lying on south facing slopes.

Tendency

The weather conditions will give rise to increasing consolidation of the snowpack.
