Deferegger Alps East

Fresh wind slabs represent the main danger.

Fresh wind slabs represent the main danger.

The fresh wind slabs are in some cases prone to triggering. They can be released by a single winter sport participant especially on steep shady slopes above approximately 2200 m. The mostly small wind slabs are clearly recognisable to the trained eye. At elevated altitudes the avalanche prone locations are more prevalent, in particular adjacent to ridgelines. Avalanches can in very isolated cases be released in the old snowpack, in particular by large additional loads. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack on extremely steep shady slopes at elevated altitudes. The avalanche prone locations are but are barely recognisable.

As a consequence of the occasionally strong wind, fresh snow drift accumulations formed during the last few days. The fresh wind slabs are poorly bonded with the old snowpack especially on wind-protected shady slopes at elevated altitudes. Faceted weak layers exist in the centre of the snowpack. The old snowpack will be prone to triggering in some places, especially in little used terrain on very steep shady slopes.

The avalanche danger will decrease gradually. Individual avalanche prone locations are to be found in particular on steep, little used shady slopes.
