Avalanche Activity
Weak layers in the old snowpack necessitate caution.
Avalanches can in some places be released in the weakly bonded old snow, even by a single winter sport participant, in particular on steep west, north and east facing slopes between approximately 2200 and 2600 m. Caution is to be exercised at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Avalanches can in some cases reach quite a large size. In addition the fresh wind slabs are capable of being triggered in some locations. Adjacent to ridgelines and in gullies and bowls the avalanche prone locations are more prevalent.
Snowpack Structure
In its middle, the snowpack is faceted and weak, especially on shady slopes between approximately 2200 and 2600 m. Snow profiles and stability tests confirm this situation. As a consequence of the occasionally strong northerly wind, fresh snow drift accumulations will form on Saturday. The fresh wind slabs are poorly bonded with the old snowpack especially on wind-protected shady slopes.
Tendency
The avalanche danger will decrease gradually.
