Avalanche Activity

Fresh and older wind slabs represent the main danger.

The mostly small wind slabs are clearly recognisable. These can at their margins be released by people and reach medium size. The avalanche prone locations are to be found in particular in extremely steep terrain and at transitions into gullies and bowls, this also applies adjacent to ridgelines and in pass areas. Additionally avalanches can also be released in near-ground layers. Whumpfing sounds serve as an alarm sign. From the afternoon the wind will be strong. Over a wide area 10 to 20 cm of snow will fall above approximately 500 m. As a consequence of the strong southeasterly wind, fresh snow drift accumulations will form in the afternoon. Small and, in isolated cases, medium-sized natural dry avalanches are possible.

Snowpack Structure

As a consequence of a strong wind from northwesterly directions, hard wind slabs formed over a wide area. The strong wind has transported the fresh and old snow significantly. Faceted weak layers exist in the bottom section of the snowpack at intermediate and high altitudes. In all aspects below approximately 2000 m from a snow sport perspective, in most cases insufficient snow is lying.

Tendency

Little snow will fall until late morning.
