Wind slab

The fresh wind slabs are prone to triggering. Weak layers in the old snowpack necessitate caution.
The fresh wind slabs are prone to triggering. Weak layers in the old snowpack necessitate caution.
The fresh snow and in particular the wind slabs formed by the strong to storm force northwesterly wind can be released by a single winter sport participant. The avalanche prone locations are to be found on steep shady slopes above the tree line. Adjacent to ridgelines and in gullies and bowls the avalanche prone locations are more prevalent. Avalanches can in some places be released in deeper layers, even by a single winter sport participant. This applies on steep west, north and east facing slopes between approximately 2200 and 2600 m. Avalanches can in some cases reach dangerously large size. On extremely steep sunny slopes individual small loose snow avalanches are possible as a consequence of warming during the day and solar radiation.
10 to 20 cm of snow has fallen. Up to 10 cm of snow will fall until the afternoon. The wind will be strong to storm force over a wide area. As a consequence of new snow and northwesterly wind, wind slabs will form in all aspects. The fresh wind slabs are bonding poorly with the old snowpack in particular on wind-protected shady slopes. They are prone to triggering. In its middle, the snowpack is faceted and weak, especially on shady slopes between approximately 2200 and 2600 m.
As a consequence of a sometimes strong southwesterly wind, further wind slabs will form.
