During the clear night into Sunday, the surface of the snowpack will freeze above approximately 2000 m to become capable of bearing loads. Sunshine will cause it to soften during the course of the day.
Moisture penetration into 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 mainly affects north-facing slopes between approximately 2200 and 2500 m, and east- and west-facing slopes between approximately 2500 and 2800 m. On south-facing slopes, moisture penetration into the snowpack extends as far as the high alpine regions. In Grisons, the weak layers in the old snowpack are the least deeply buried, which means that wet slab avalanches can also be triggered by human activity in some places.
Higher up, the snowpack is still dry. There are still weak layers in the old snowpack.
In general, hardly any avalanches have been reported in recent days.
