Fresh wind slabs require caution.

Fresh wind slabs require caution.

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, caution is to be exercised in particular adjacent to ridgelines and in pass areas on very steep slopes. In high Alpine regions these avalanche prone locations are more prevalent. Small dry avalanches are possible. The avalanche prone locations are to be found in particular on very steep slopes at intermediate and high altitudes. As the day progresses as a consequence of warming during the day and solar radiation there will be a gradual increase in the danger of moist and wet avalanches.

10 to 20 cm of snow, and even more in some localities, has fallen since Friday 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.

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