Western Nonsberg Alps

The new snow and wind slabs of the last few days must be evaluated with care and prudence.

The new snow and wind slabs of the last few days must be evaluated with care and prudence.

The fresh snow and the wind slabs formed during the snowfall are lying on top of a weakly bonded old snowpack. Caution is to be exercised in particular on very steep shady slopes, as well as adjacent to ridgelines and in gullies and bowls in particular above the tree line. Especially here avalanches can be triggered in the faceted old snow. This applies even in case of a small load. The avalanche prone locations are covered with new snow and are barely recognisable.

Up to 30 cm of snow, and even more in some localities, has fallen. As a consequence of new snow and a moderate southerly wind, mostly small wind slabs formed. The fresh and older wind slabs are lying on top of a weakly bonded old snowpack. They are bonding only slowly with the old snowpack. Precarious weak layers exist in the bottom section of the snowpack on wind-protected shady slopes. The old snowpack consists of faceted crystals.
