Western Nonsberg Alps

New snow and wind slabs require caution.

New snow and wind slabs require caution.

As a consequence of new snow and wind from southwesterly directions, avalanche prone wind slabs will form. They can be released even by a single winter sport participant. Mostly the avalanches are medium-sized. The avalanche prone locations are to be found in particular on steep slopes above approximately 2000 m, and adjacent to ridgelines and in gullies and bowls. In particular in regions exposed to heavier precipitation and in the regions neighbouring those that are subject to danger level 3 (considerable) the avalanche prone locations are more widespread and the danger is greater. As a consequence of the snowfall more natural loose snow slides are possible as the day progresses, even medium-sized ones. Areas with glide cracks are to be avoided. This applies in particular on steep grassy slopes in all aspects especially above the tree line.

10 to 20 cm of snow will fall on Sunday above approximately 1800 m. The sometimes storm force wind will transport the new snow significantly. The fresh wind slabs will be deposited on the unfavourable surface of an old snowpack in all aspects in all altitude zones.

Wind slabs are to be evaluated with care and prudence. The weather conditions will facilitate a gradual stabilisation of the snow drift accumulations. A latent danger of gliding avalanches exists. As the precipitation eases individual loose snow avalanches are to be expected.
