Western Nonsberg Alps

Wind slabs require caution.

Wind slabs require caution.

As a consequence of the occasionally strong northwesterly wind, fresh snow drift accumulations formed on Friday. This applies especially adjacent to ridgelines and in gullies and bowls. The avalanche prone locations are rather rare and are clearly recognisable to the trained eye. The wind slabs of the last few days can be released easily above approximately 2200 m. Caution is to be exercised at their margins in particular. Mostly the avalanches are small. In isolated cases avalanches can be triggered in the weakly bonded old snow. Such avalanche prone locations are to be found in particular on extremely steep shady slopes above approximately 2600 m. In very isolated cases avalanches are medium-sized. Even a small avalanche can sweep snow sport participants along and give rise to falls.

The fresh wind slabs are bonding poorly with the old snowpack. The fresh and older wind slabs are lying on the unfavourable surface of an old snowpack in particular on wind-protected shady slopes. The snowpack will be subject to considerable local variations. In all regions a little snow is lying.

The avalanche danger will persist.
