As a consequence of a strong westerly wind, avalanche prone wind slabs will form. Fresh wind slabs are to be evaluated critically. Gliding snow requires caution.

Since Tuesday avalanche prone wind slabs will form adjacent to ridgelines and in gullies and bowls. Avalanches can in some cases be released, even by a single winter sport participant and reach medium size. At intermediate altitudes these can release the wet old snow as well. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. On steep grassy slopes medium-sized and, in isolated cases, large gliding avalanches are possible. This applies especially on steep slopes below approximately 2600 m. Areas with glide cracks are to be avoided.

The fresh wind slabs are lying on soft layers in particular on northwest to north to east facing aspects at elevated altitudes. The older wind slabs of the weekend are now only very rarely prone to triggering. Outgoing longwave radiation during the night will be quite good over a wide area. The surface of the snowpack will freeze to form a strong crust and will soften during the day. This applies in particular on sunny slopes at intermediate and high altitudes, as well as on shady slopes below approximately 2200 m.

As a consequence of rising temperatures the snow drift accumulations stabilised. The danger of moist avalanches will increase.
