Wind slabs are to be evaluated with care and prudence.

Wind slabs are to be evaluated with care and prudence.

The wind slabs of the last few days represent the main danger. They are mostly only small but prone to triggering. They can be released even by a single winter sport participant especially on steep shady slopes above approximately 2200 m. The avalanche prone locations are to be found in particular in places that are protected from the wind and in gullies and bowls, and behind abrupt changes in the terrain. Avalanches can in very isolated cases be released in deeper layers also. This applies on steep west, north and east facing slopes between approximately 2200 and 2600 m. Avalanches can reach large size in isolated cases.

As a consequence of a moderate to strong southwesterly wind, further wind slabs will form on Thursday. The fresh and older wind slabs are bonding poorly with the old snowpack in particular on wind-protected shady slopes. They are mostly easy to recognise but prone to triggering. In its middle, the snowpack is faceted and weak, especially on shady slopes between approximately 2200 and 2600 m.

The fresh wind slabs represent the main danger. As a consequence of falling temperatures and the light to moderate westerly wind, the snow drift accumulations will stabilise during the next few days.
