Kernpunkte

Fresh wind slabs are to be evaluated critically. Weak layers in the old snowpack can be released in isolated cases.

Snowpack Structure

Distinct weak layers exist in the old snowpack in particular on west, north and east facing slopes. Outgoing longwave radiation during the night will be reduced. The weather conditions as the day progresses will give rise to gradual and thorough wetting of the snowpack. This applies on very steep sunny slopes below approximately 2200 m.

Tendency

The activity of wet avalanches will slowly increase.

Avalanche Activity

Fresh wind slabs are to be evaluated critically. Weak layers in the old snowpack can be released in isolated cases.

Avalanches can in isolated cases be released in the old snowpack and reach medium size in isolated cases on west, north and east facing slopes. This applies in case of a single winter sport participant. In their paths avalanches can entrain the wet snow. This extends the avalanche runout distances. As a consequence of warming during the day and solar radiation small and medium-sized wet avalanches are possible. This applies in particular on very steep sunny slopes below approximately 2200 m. The runout zones are to be treated with caution.
