Snowpack Structure

25 to 40 cm of snow, and even more in some localities, will fall until Saturday above approximately 1500 m. Adjacent to ridgelines and in gullies and bowls further wind slabs will form. Various wind slab layers are lying on a weakly bonded old snowpack, in particular on steep shady slopes. Especially sunny slopes as well as low and intermediate altitudes: The upper section of the snowpack is largely stable and its surface has a crust that is strong in many cases. Especially very steep shady slopes, above approximately 2200 m: The upper section of the snowpack is weak in some cases; its surface consists of loosely bonded snow.

Tendency

As a consequence of the new snow the avalanche prone locations will become more prevalent as the day progresses.

Avalanche Activity

New snow and wind slabs require caution.

Above approximately 1200 m snow will fall until Sunday. Adjacent to ridgelines and in gullies and bowls wind slabs will form. On very steep shady slopes the avalanches can be released in deep layers of the snowpack and reach quite a large size. The new snow and wind slabs can be released by a single winter sport participant in some cases in particular on steep shady slopes above approximately 2200 m, in particular in gullies and bowls, and behind abrupt changes in the terrain.
