Fresh wind slabs require caution.
The southerly wind will transport the new snow. In the course of the day further wind slabs will form in particular on west, north and east facing slopes. Avalanches can in many places be released, even by a single winter sport participant and reach medium size. 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 steep grassy slopes medium-sized gliding avalanches are possible as a consequence of the new snow, in particular on sunny slopes below approximately 2400 m.
20 cm of snow, and even more in some localities, fell on Friday. The strong wind will transport the new snow significantly. The new snow and wind slabs will be deposited on soft layers in particular on west to north to east facing aspects above approximately 2200 m. In some cases wind slabs are lying on a weakly bonded old snowpack, in particular on steep west and east facing slopes above approximately 2400 m, as well as on steep north facing slopes above approximately 2200 m.
The fresh wind slabs remain prone to triggering. More frequent loose snow avalanches are to be expected as the day progresses, even medium-sized ones, in the event of solar radiation especially on extremely steep sunny slopes. The activity of gliding avalanches will increase, in particular on steep east, south and west facing slopes below approximately 2400 m.
