Persistent weak layers
- Above treeline
More recent wind slabs can be released easily, even by a single winter sport participant, above approximately 1900 m, especially at their margins. The spring-like weather conditions gave rise to moistening of the snowpack below approximately 2400 m. Snow depths vary greatly, depending on the infuence of the wind. Weak layers in the old snowpack necessitate caution and restraint.
As a consequence of wind from northwesterly directions, sometimes avalanche prone wind slabs formed in all aspects. Avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain above approximately 1900 m. On steep slopes more wet loose snow avalanches are possible as a consequence of warming during the day and solar radiation.
