Avalanche Activity

More slab avalanches are possible, in particular medium-sized ones.

Artificially triggered avalanches and whumpfing sounds and the formation of shooting cracks when stepping on the snowpack confirm a treacherous avalanche situation on steep shady slopes. Adjacent to ridgelines and in gullies and bowls soft wind slabs formed. 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 2300 m, in particular in gullies and bowls, and behind abrupt changes in the terrain. In the regions exposed to a lot of new snow caution is to be exercised in particular in little used terrain and. Careful route selection and spacing between individuals are recommended.

Snowpack Structure

2 to 5 cm of snow, but less in some localities, fell on Tuesday above approximately 1200 m. Adjacent to ridgelines and in gullies and bowls soft wind slabs formed. New snow and wind slabs are lying on a weakly bonded old snowpack, in particular on steep shady slopes. Sunshine and high temperatures gave rise to increasing consolidation of the snowpack over a wide area in all aspects below approximately 3000 m. 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.

Tendency

The weather will be mild. The avalanche danger will decrease gradually.
