Wind slabs represent the main danger. The wind slabs are to be found in particular adjacent to ridgelines and in gullies and bowls and generally at high altitudes.

Wind slabs represent the main danger. The wind slabs are to be found in particular adjacent to ridgelines and in gullies and bowls and generally at high altitudes.
The wind slabs are mostly easy to recognise but can be released by large loads at their margins in particular. Weak layers in the old snowpack represent the main danger. In isolated cases the avalanches are medium-sized and can mostly be released by large loads, caution is to be exercised in particular on very steep shady slopes above approximately 2400 m on wind-loaded slopes.
The snowpack remains subject to considerable local variations above approximately 2400 m. The wind slabs are lying on top of a weakly bonded old snowpack on shady slopes at elevated altitudes. Faceted weak layers exist in the bottom section of the old snowpack in shady places that are protected from the wind. At low and intermediate altitudes thus far only a little snow is lying.
Some snow will fall over a wide area. The fresh snow and the mostly small wind slabs are lying on the unfavourable surface of an old snowpack on north to northeast to northwest facing aspects above approximately 900 m.
