Snowpack Structure

Over a wide area over a wide area 20 to 30 cm of snow, and even more in some localities, fell on Saturday above approximately 2300 m. New snow and wind slabs are lying on a moist old snowpack. This also applies on shady slopes in particular below approximately 2800 m. Below approximately 2000 m a little snow is lying.

Avalanche Activity

The wind slabs can be released even by a single winter sport participant in particular on steep shady slopes and generally at high altitudes and in high Alpine regions.

As a consequence of new snow and wind, sometimes large wind slabs formed in particular in places that are protected from the wind. The wind slabs can be released by a single winter sport participant in some cases above approximately 2500 m. This applies in particular on steep slopes, and on very steep slopes. In these regions occasionally large avalanches are possible in particular at high altitudes and in high Alpine regions. As the day progresses as a consequence of warming during the day there will be an increase in the danger of moist and wet avalanches. Backcountry tours should be started and concluded early. The current avalanche situation calls for experience in the assessment of avalanche danger and careful route selection.
