Saturation of the snowpack is well advanced. The most precarious areas are slopes where weak layers in the old snowpack are becoming wet for the first time. At present, this is mainly affecting north-facing slopes between approximately 2200 and 2500 m, and east- and west-facing slopes between approximately 2500 and 2800 m. In many places, south-facing slopes are snow-free up to around 3000 m; where there is still snow, it is saturated as far as the high alpine regions.
In the north above approximately 2000 m, the mainly clear overnight conditions are resulting in the formation of a load-bearing crust, which softens over the course of the day. There is less outgoing longwave radiation in the south with only a thin crust being formed.
