New snow and wind slabs require caution.
Wind slabs 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. Weak layers in the old snowpack can be released easily in particular on very steep shady slopes. As a consequence of warming during the day and solar radiation 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 fresh wind slabs are poorly bonded with the old snowpack in all aspects and at elevated altitudes. 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.
