10 to 20 cm of snow, and even more in some localities, fell yesterday above approximately 1400 m. Over a wide area 25 to 40 cm of snow will fall until late in the night above approximately 1200 m. The fresh snow and the wind slabs that are forming at high altitudes and in high Alpine regions can be released easily, even by a single winter sport participant,. As a consequence of new snow and wind they will increase in size during the night. Individual weak layers exist deep in the old snowpack in particular on steep northwest, north and east facing slopes. Avalanches can in isolated cases be released in deep layers and reach large size in isolated cases.

The high humditiy gave rise on Saturday to moistening of the snowpack over a wide area at low and intermediate altitudes. 10 to 20 cm of snow, and even more in some localities, fell yesterday above approximately 1400 m.
