Wind slab
- Above 1,600 m
Fresh wind slabs represent the main danger.
Fresh wind slabs represent the main danger.
The fresh and older wind slabs are to be evaluated with care and prudence in all aspects above approximately 1600 m. These are in some cases extensive and can be released easily. Mostly avalanches are medium-sized. In the regions exposed to heavier precipitation the avalanche danger is a little higher.
20 to 30 cm of snow, and even more in some localities, has fallen since Saturday. Up to 15 cm of snow will fall on Sunday in all altitude zones. As a consequence of new snow and a moderate to strong wind from variable directions, further wind slabs will form in all aspects, in particular above approximately 1600 m. In very isolated cases weak layers exist in the centre of the snowpack, especially on shady slopes above approximately 2200 m.
In some cases the various wind slabs have bonded still only poorly with each other and the old snowpack. The weather conditions will bring about a slow change towards better conditions.
