Fresh wind slabs are to be evaluated with care and prudence. On steep grassy slopes individual gliding avalanches are possible.
The fresh wind slabs can be released easily, even by a single winter sport participant, on steep west, north and east facing slopes above approximately 2200 m. Avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain. In the regions exposed to the foehn wind these avalanche prone locations are more prevalent. Avalanches can reach medium size in isolated cases especially in these regions. The clearly visible wind slabs are to be avoided. On steep grassy slopes individual gliding avalanches are possible, especially on sunny slopes below approximately 2400 m. Caution is to be exercised in areas with glide cracks.
As a consequence of a strengthening southerly foehn wind, mostly shallow wind slabs formed since Monday in gullies and bowls and behind abrupt changes in the terrain. During the course of the night these will increase in size additionally. The fresh wind slabs are lying on soft layers especially on west, north and east facing slopes. In some places wind slabs are lying on surface hoar. Isolated avalanche prone weak layers exist in the bottom section of the snowpack on shady slopes. This applies in particular in places that are protected from the wind at elevated altitudes.
Fresh wind slabs are in some cases prone to triggering. Gliding snow requires caution.
