Avalanche Activity

Wind slabs and weakly bonded old snow require caution.

The fresh and older wind slabs can be released easily, even by a single winter sport participant, in particular on northwest to north to northeast facing aspects above approximately 2000 m. Avalanches can in isolated cases be released in the old snowpack and reach quite a large size on very steep northwest, north and northeast facing slopes. As a consequence of warming during the day and solar radiation small and, in isolated cases, medium-sized moist loose snow avalanches are possible.

Snowpack Structure

Very steep, little used shady slopes: Avalanche prone weak layers exist in the old snowpack in particular on northwest, north and northeast facing slopes. This applies at high altitude. Outgoing longwave radiation during the night will be good in some case. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack.

Tendency

Fresh wind slabs are in some cases still prone to triggering in particular on steep shady slopes. The avalanche danger will decrease gradually.
