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. In particular above approximately 2300 m these avalanche prone locations are more prevalent. Such avalanche prone locations are barely recognisable, even to the trained eye. They can be released by a single winter sport participant. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and released avalanches confirm an unfavourable avalanche situation on steep slopes.

15 to 30 cm of snow fell on Sunday above approximately 2500 m. On Sunday on very steep shady slopes numerous medium-sized and, in isolated cases, large avalanches were released. The solar radiation gave rise as the day progresses to moistening of the snowpack below approximately 2500 m. The new snow and wind slabs are lying on a crust on steep sunny slopes. In particular at intermediate altitudes less snow than usual is lying. On sunny slopes below approximately 2400 m hardly any snow is lying.

The avalanche danger will decrease gradually.
