Western Nonsberg Alps

The wind slabs are to be assessed with care and prudence.

The wind slabs are to be assessed with care and prudence.

As a consequence of new snow and a moderate to strong wind from southwesterly directions, sometimes avalanche prone wind slabs will form adjacent to ridgelines and in gullies and bowls as well as at high altitudes and in high Alpine regions. Natural avalanches are possible in isolated cases. Mostly avalanches are small. On wind-loaded slopes medium-sized avalanches are possible. Avalanches can be released by a single winter sport participant. The avalanche prone locations are to be found in all aspects above approximately 1800 m. Caution is to be exercised in gullies and bowls, and behind abrupt changes in the terrain, as well as adjacent to ridgelines.

Over a wide area 10 to 30 cm of snow will fall in the next few hours above approximately 1000 m. During the night sometimes avalanche prone wind slabs will form in some localities. Towards its base, the snowpack is faceted and weak.

Fresh wind slabs represent the main danger. 10 to 20 cm of snow, and even more in some localities, will fall from the afternoon.
