Fresh wind slabs are to be evaluated with care and prudence. More frequent small and, in isolated cases, medium-sized loose snow avalanches are to be expected.
The fresh wind slabs must be evaluated with care and prudence in particular on northwest to north to southeast facing aspects above approximately 2000 m. They can be released by a single winter sport participant in some cases. Avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls, and behind abrupt changes in the terrain. They are barely recognisable because of the poor visibility. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. Avalanches can reach medium size. As the precipitation eases more frequent small to medium-sized loose snow avalanches are to be expected. In addition very occasional medium-sized gliding avalanches are possible. This applies on steep grassy slopes below approximately 2600 m. Areas with glide cracks are to be avoided.
20 to 40 cm of snow, and even more in some localities, will fall. The wind will be strong in some cases. As a consequence of new snow and wind, avalanche prone wind slabs will form in some places. They are lying on soft layers above approximately 2000 m. The old snowpack is moist and its surface has a resilient melt-freeze crust. This applies on sunny slopes in all altitude zones, as well as on shady slopes below approximately 2600 m.
Fresh wind slabs represent the main danger. Loose snow avalanches are to be expected.
