Wind slab
- Above 2,000 m
New snow and wind slabs represent the main danger.
New snow and wind slabs represent the main danger.
In the last few days sometimes large wind slabs formed especially adjacent to ridgelines and in gullies and bowls as well as at high altitude. These can be released by a single winter sport participant. As a consequence of solar radiation dry and moist avalanches are possible as the day progresses, even quite large ones. This applies in particular in steep rocky terrain.
In some regions 40 to 60 cm of snow, and even more in some localities, has fallen since Sunday above approximately 2000 m. The sometimes strong wind has transported the new snow. The old snowpack is well consolidated and its surface consists of loosely bonded snow lying on a resilient melt-freeze crust. In some cases the wind slabs have bonded poorly with each other and the old snowpack. Above approximately 2100 m a lot of snow is lying.
