Wind slab
- Above 2,200 m
The sometimes strong wind has transported the new snow.
The sometimes strong wind has transported the new snow.
As a consequence of the moderate to strong northeasterly wind, fresh snow drift accumulations will form by the early morning. These can especially at their margins be released by a single winter sport participant and reach medium size. The avalanche prone locations are to be found in particular on northwest to west to southwest facing aspects, in particular at transitions from a shallow to a deep snowpack. Additionally avalanches can also be released in near-ground layers and reach quite a large size. Whumpfing sounds serve as an alarm indicating the danger. The wind slabs of last week are covered with new snow and therefore barely recognisable. Isolated small and medium-sized natural dry avalanches are possible, especially in case of releases originating from extremely steep starting zones at intermediate and high altitudes that have retained the snow thus far. Such avalanche prone locations are to be found especially in steep rocky terrain.
15 to 30 cm of snow has fallen since Monday above approximately 2000 m. As a consequence of a moderate to strong wind from easterly directions, wind slabs formed in the last two days. Faceted weak layers exist in the bottom section of the snowpack at intermediate and high altitudes. In all aspects below approximately 2400 m less snow than usual is lying.
The avalanche danger will persist.
