Caution: mild persistent weak layer and gliding snow problem
Avalanche danger is low. Main problem: persistent weak layer in old snow. Small to medium-sized slab avalanches are possibly triggered mostly by large additional loading. The few danger zones occur in transitions from shallow to deeper snow in extremely steep terrain on W/N/E facing slopes. In addition, isolated naturally triggered generally small glide-snow avalanches are possible, esp. on smooth, steep grass-covered slopes in all aspects.
The snowpack has settled considerably and is largely stable. In shady higher altitude terrain, weak layers consisting of faceted crystals persist under melt-freeze crusts. On the sunny side a thin melt-freeze crust will form on the surface during the night and soften again during the course of the day. The snowpack base is partly wet at ground level, as a consequence the snowpack can start gliding over smooth ground.
Avalanche danger levels will remain low.
