Avalanche Activity

Wind slabs represent the main danger. Weakly bonded old snow requires caution.

As a consequence of a storm force wind from northerly directions, clearly visible wind slabs formed in all aspects. These can be released even by a single winter sport participant above approximately 2200 m. Caution is to be exercised in particular at the base of rock walls and behind abrupt changes in the terrain, as well as adjacent to ridgelines and in gullies and bowls. Mostly avalanches are medium-sized. Shooting cracks when stepping on the snowpack can indicate the danger. Additionally in isolated cases avalanches can penetrate near-ground layers of the snowpack and reach large size, especially on west, north and east facing slopes above approximately 2200 m, and on south facing slopes at elevated altitudes.

Snowpack Structure

The gusty wind has transported the fresh and old snow significantly. In some cases the various wind slabs have bonded still only poorly together. The old snowpack will be weakly bonded in some places, especially on west, north and east facing slopes above approximately 2200 m, and on south facing slopes at elevated altitudes.

Tendency

Wind slabs and weakly bonded old snow require caution.
