Avalanche Activity

Fresh wind slabs require caution. In particular at high altitude the avalanche prone locations are more widespread. Gradual increase in danger of moist and wet avalanches in the course of the day.

As a consequence of the strong northwesterly wind, the snow drift accumulations have increased in size. The mostly small wind slabs remain in some cases prone to triggering at high altitude. These can be released by a single winter sport participant in isolated cases, especially adjacent to ridgelines and in pass areas on very steep slopes. Restraint should be exercised because avalanches can sweep people along and give rise to falls. In high Alpine regions these avalanche prone locations are more prevalent. As the day progresses as a consequence of warming during the day and solar radiation there will be an increase in the danger of moist and wet avalanches within the current danger level. In particular on very steep sunny slopes small and, in isolated cases, medium-sized wet avalanches are possible as the day progresses.

Snowpack Structure

10 to 20 cm of snow, and even more in some localities, fell in the last few days above approximately 2300 m. In these regions in all altitude zones only a small amount of snow is lying for the time of year. On sunny slopes as well as below approximately 2300 m from a snow sport perspective, in most cases insufficient snow is lying. At high altitudes and in high Alpine regions snow depths vary greatly, depending on the infuence of the wind. Individual weak layers exist in the snowpack on shady slopes.

Tendency

The danger of moist and wet avalanches will increase a little during the day, in the event of prolonged bright spells especially.
