As a consequence of new snow and wind the prevalence and size of the avalanche prone locations will increase from the second half of the night.

As a consequence of new snow and a freshening southeasterly wind, wind slabs will form from the second half of the night in particular adjacent to ridgelines and in pass areas as well as above approximately 2000 m. Fresh wind slabs must be evaluated with care and prudence. In particular at intermediate and high altitudes the prevalence and size of the avalanche prone locations will increase. They can be released by a single winter sport participant. The current avalanche situation calls for experience and restraint. Small and medium-sized natural avalanches are possible as the snowfall becomes more intense, also in all aspects on steep slopes.

30 to 50 cm of snow will fall until Sunday above approximately 1500 m. The new snow is bonding poorly with the old snowpack in some places. Caution is to be exercised on wind-protected shady slopes. Towards its surface, the snowpack is unfavourably layered and its surface consists of surface hoar. A lot of snow is lying at intermediate and high altitudes.

The avalanche danger will persist.
