Western Nonsberg Alps

The fresh snow as well as the wind slabs represent the main danger.

The fresh snow as well as the wind slabs represent the main danger.

As a consequence of a moderate to strong northeasterly wind, sometimes avalanche prone wind slabs will form in some places. The fresh wind slabs can be released by a single winter sport participant. Mostly the avalanches are small. The avalanche prone locations are to be found in particular in steep terrain and adjacent to ridgelines and in gullies and bowls. Avalanches can additionally be released in the old snowpack in isolated cases. These avalanche prone locations are rare but are difficult to recognise. Experience in the assessment of avalanche danger is required.

In some regions 5 to 10 cm of snow, and up to 20 cm in some localities, has fallen, especially in the eastern Prealps. As a consequence of a strengthening wind from northeasterly directions, further wind slabs will form on Friday. These are mostly small and in some cases prone to triggering. The new snow and wind slabs of the last few days are poorly bonded with the old snowpack in some places. Isolated avalanche prone weak layers exist in the old snowpack, especially on steep, little used shady slopes.

On Friday it will be sunny at times. Until Saturday the wind will be moderate to strong over a wide area. The avalanche danger will increase but remain within the current danger level.
