Fresh wind slabs represent the main danger.

Fresh wind slabs represent the main danger.

As a consequence of new snow and a sometimes moderate southeasterly wind, further wind slabs will form by Sunday. The avalanche prone locations are covered with new snow and are therefore difficult to recognise. The fresh snow and the wind slabs can be released by a single winter sport participant in some cases on shady slopes. This applies especially at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example on very steep slopes. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack indicate a precarious avalanche situation.

15 to 25 cm of snow fell in the last six days above approximately 2300 m. The wind was moderate to strong in some localities. 5 to 20 cm of snow, and even more in some localities, will fall until Sunday above approximately 2000 m. The high humditiy gave rise to moistening of the old snowpack in all aspects below approximately 2400 m. The new snow and wind slabs are lying on a crust on steep sunny slopes. In shady places that are protected from the wind above approximately 2300 m: The new snow is lying on the unfavourable surface of an old snowpack. In all aspects less snow than usual is lying. Adjacent to ridgelines and in pass areas and at high altitude a little snow is lying. At low altitude less snow than usual is lying.

The avalanche danger will persist.
