The current avalanche situation calls for careful route selection.

The current avalanche situation calls for careful route selection.

The new snow and wind slabs of last week are lying on the unfavourable surface of an old snowpack on shady slopes. The fresh snow and the wind slabs can be released by a single winter sport participant in some cases. 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. In particular above approximately 2400 m these avalanche prone locations are more prevalent.

5 to 10 cm of snow, and even more in some localities, fell on Sunday above approximately 2000 m. The solar radiation gave rise as the day progresses to moistening of the snowpack below approximately 2400 m. The new snow and wind slabs are lying on a crust on steep sunny slopes. 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.
