The northwesterly wind has transported the fresh and old snow significantly. Wind slabs can in some places be released by a single winter sport participant and reach medium size. In some localities 2 to 5 cm of snow, but less in some localities, will fall until Sunday above approximately 1800 m.

The wind was strong to storm force over a wide area. The wind has transported the fresh and old snow significantly. Over a wide area snow depths vary greatly, depending on the infuence of the wind. Towards its surface, the snowpack is hard and its surface has a crust that is strong in many cases, in particular adjacent to ridgelines and in pass areas.
