During the mostly clear night into Monday, the surface of the snowpack will freeze above approximately 2000 m once again 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 occasionally be triggered by human activity.
In areas higher up, where the snowpack is still dry, weak layers in the old snowpack are still present, but are unlikely to be triggered anymore.
In general, no further avalanches triggered by human activity have been reported in the last seven days.
