The new snow represents the main danger.

The new snow represents the main danger.

Over a wide area up to 30 cm of snow, and up to 40 cm in some localities, will fall until the early morning above approximately 800 m. This snow must be evaluated with care and prudence in particular on steep shady slopes above the tree line. In particular in the regions exposed to heavier precipitation individual small and medium-sized slab avalanches are to be expected as the snowfall becomes more intense. The new snow can be released by a single winter sport participant especially on shady slopes at high altitude. As a consequence of new snow and wind, wind slabs will form during the night in particular adjacent to ridgelines.

The new snow is lying on the unfavourable surface of an old snowpack on steep shady slopes at high altitude. The old snowpack consists of faceted crystals.

Fresh wind slabs are to be evaluated with care and prudence.
