Wind slab
- Above treeline
Wind slabs and weakly bonded old snow represent the main danger.
Wind slabs and weakly bonded old snow represent the main danger.
As a consequence of the strong northerly wind, snow drift accumulations will form. The fresh and somewhat older wind slabs must be evaluated with care and prudence. They can be released even by a single winter sport participant above the tree line. Slopes adjacent to ridgelines are especially unfavourable. Additionally avalanches can also be released in deep layers. Such avalanche prone locations are to be found on steep, little used shady slopes above approximately 2200 m and on steep sunny slopes above approximately 2500 m. Mostly avalanches are medium-sized.
The wind will transport the loosely bonded old snow. Faceted weak layers exist in the old snowpack, especially on shady slopes above approximately 2200 m, as well as on sunny slopes above approximately 2500 m.
Fresh wind slabs require caution. As a consequence of a strong wind from northerly directions, further wind slabs will form on Tuesday. The snowpack remains in some cases prone to triggering.
