Wind slab
- Above 2,200 m
On the northern Alpine ridge some new snow. The avalanche-prone wind slabs represent the main danger.
On the northern Alpine ridge some new snow. The avalanche-prone wind slabs represent the main danger.
The wind slabs can be released easily, even by a single winter sport participant, in all aspects above the tree line. This applies in particular on wind-loaded slopes, as well as adjacent to ridgelines and in gullies and bowls. Weak layers exist in the old snowpack in particular at elevated altitudes. Especially on steep north, northeast and northwest facing slopes the avalanches can be released in deep layers of the snowpack and reach large size in some cases. As the temperature drops hardly any more natural avalanches are to be expected.
The sometimes large wind slabs are poorly bonded with the old snowpack. The wind slabs are lying on unfavourable layers in all aspects. High Alpine regions: Weak layers exist in the old snowpack especially on north, northeast and northwest facing slopes. Low and intermediate altitudes, south, southeast and southwest facing slopes: The weather conditions fostered a gradual strengthening of the snowpack.
