Wind slab
- Above 2,400 m
The wind has transported the loosely bonded old snow. There is a danger of falling on the hard crust.

The wind was strong to storm force in the regions exposed to the foehn wind. In the last few days mostly small wind slabs formed in particular at high altitude. The wind slabs can be released in all aspects. As the temperature drops hardly any more moist and wet avalanches are to be expected. The weather will be clear. The surface of the snowpack has frozen to form a strong crust. In steep terrain there is a danger of falling on the hard snow surface.
Some snow fell in the last two days especially along the border with Switzerland. In some localities 5 to 20 cm of snow has fallen above approximately 2000 m. The snowpack is favourably layered. This applies in particular at low and intermediate altitudes. The snowpack is hard and its surface has a melt-freeze crust. The surface of the snowpack will hardly soften at all. This applies in particular on shady slopes as well as at high altitude. At intermediate and high altitudes there is more snow than usual.
