The nights will be clear, the days sunny. The zero-degree level will be around 3000 m. The winds will be mostly light.
In the early morning, touring conditions will be favourable over a wide area. Each day, the danger of wet avalanches will increase appreciably as the day progresses. Tours and hut ascents should be started early and finished in good time.

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. While there are still weak layers in the old snowpack, no dry avalanches have been reported for days.
