Stability: fair · Frequency: some
Avalanche danger changes little. As wind intensifies by mid-week, fresh small-scale snowdrifts can accumulate.
Avalanche prone locations mainly occur in north aspects and ridgeline terrain.
Avalanche danger above 2200m is moderate, below that altitude danger is low. Weak layers in the old snowpack are the main problem. Slab avalanches can trigger especially by large additional loading and in transition from shall to deep snow. Avalanche prone locations mainly occur in highest altitudes in steep shady terrain close to ridges, where medium-sized avalanches cannot be ruled out. Isolated small glide-snow avalanches can trigger naturally on steep grassy slopes and rock plates where there is sufficient snow on the ground.
At night, a breakable crust forms on south-facing slopes which softens fast. Dry snow is to be found on shady slopes. A layer consisting of faceted (expansively metamorphosed) crystals formed, where there are wind crusts in high altitude terrain on the shady side. At high altitudes, there are isolated layers of faceted crystals also underneath older snowdrift masses. At low altitudes the snowpack is shallow, moist down to the ground. Gliding movements over smooth grass-covered slopes cannot be excluded.
