In sintesi

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

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 2200 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 reach medium size. They can in isolated cases penetrate deep layers and reach dangerously large size. In the south the avalanches are mostly smaller. On extremely steep sunny slopes individual small moist loose snow avalanches are possible as a consequence of warming during the day and solar radiation. On very steep grassy slopes individual gliding avalanches are possible, but they will be mostly small.

Snowpack Structure

As a consequence of snowfall and the wind, snow drift accumulations formed during the last few days. 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 wind slabs represent the main danger. Weak layers in the old snowpack necessitate caution.
