Fresh wind slabs require caution.
In the last few days clearly visible wind slabs formed. Avalanches can in some places be released by a single winter sport participant and reach medium size, in particular on steep shady slopes. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. As the day progresses more frequent small and, in isolated cases, medium-sized loose snow avalanches are to be expected, in the event of prolonged bright spells especially on extremely steep slopes. On steep grassy slopes mostly small gliding avalanches are possible, in particular on sunny slopes below approximately 2400 m.
20 cm of snow, and even more in some localities, fell on Friday. The sometimes strong wind has transported the new snow. In some cases wind slabs are lying on soft layers, in particular on steep shady slopes above the tree line.
The wind slabs are in some cases prone to triggering. In addition mostly small gliding avalanches and wet snow slides are possible.
