Avalanche Activity

Wind slabs represent the main danger. Weak layers in the lower part of the snowpack necessitate caution.

The somewhat older wind slabs can be released by a single winter sport participant in some cases above approximately 2600 m. The avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain. In particular shady slopes are unfavourable. At elevated altitudes the avalanche prone locations will become more prevalent. Avalanches can penetrate deep layers and reach medium size in isolated cases.

Snowpack Structure

In some cases the various wind slabs have bonded poorly with each other and the old snowpack. They are lying on top of a weakly bonded old snowpack in particular on northwest to north to southeast facing aspects. Sunshine and high temperatures will give rise as the day progresses to slight softening of the snowpack in particular on steep sunny slopes below approximately 2800 m. The snowpack will be subject to considerable local variations.

Tendency

Fresh and older wind slabs represent the main danger. Weak layers in the old snowpack necessitate caution.
