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. As a consequence of the new snow individual natural loose snow slides are possible as the day progresses, even quite large 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.
The wind will transport the new snow. The fresh wind slabs will be deposited on the unfavourable surface of an old snowpack in all aspects in all altitude zones. Towards its base, the snowpack consists of faceted crystals.
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.
