Avalanche Activity

Gradual increase in avalanche danger as a consequence of warming during the day and solar radiation.

The early morning will see quite favourable conditions generally. As the day progresses on steep east, south and west facing slopes there will be a gradual increase in the danger of moist and wet avalanches to level 3 (considerable). Avalanches can in isolated cases be triggered in the old snowpack and reach quite a large size. The avalanche prone locations are to be found especially in steep terrain and at transitions from a shallow to a deep snowpack. Backcountry tours should be started very early and concluded timely.

Snowpack Structure

Outgoing longwave radiation during the night will be good. The surface of the snowpack will freeze to form a strong crust and will soften earlier than the day before. The spring-like weather conditions as the day progresses will give rise to increasing moistening of the snowpack. Individual weak layers exist in the snowpack in particular on shady slopes. In particular on sunny slopes as well as at low and intermediate altitudes from a snow sport perspective, in most cases insufficient snow is lying.
