Persistent weak layer in old snow at higher altitudes. In addition, avoid zones below glide cracks.
Avalanche danger above 1800 m 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. Danger zones occur in steep ridgeline terrain, in particular in shady aspects, near ridgelines, in steep high altitude terrain and in shallow snow. Avalanches can grow to medium size. In addition, glide-snow avalanches can release spontaneously at any time of day or night. This applies in particular to steep grass-covered slopes on the sunny side; but partly also to forest aisles and rock slabs. At high altitudes they can reach medium size.
Snowpack
At night, a breakable crust forms on south-facing slopes which softens fast. On the shady side the snow is still dry, close to ridges superficially impacted by wind. In places, a trigger-sensitive weak layers persists in the snowpack underneath a melt-freeze crust On ridges there are also isolated weak layers consisting of faceted crystals under buried under older accumulated snowdrifts. At low altitudes the snowpack is shallow, moist down to the ground. Gliding movements over smooth grass-covered slopes cannot be excluded, especially at high altitudes where there is more snow.
A
Tendency
Avalanche danger changes little. As wind intensifies by mid-week, fresh small-scale snowdrifts can accumulate.
Danger level
Avalanche Problem
Gliding snow
Predominantly stable conditions.
Avalanche danger is low. Gliding snow is the main problem. Isolated small glide-snow avalanches can trigger naturally on steep grassy slopes at any time of day or night where there is sufficient snow on the ground.
Snowpack
The snowpack is largely stable. At night, a breakable crust forms on south-facing slopes which softens fast. Dry snow is to be found on shady slopes. At intermediate altitudes, isolated weak layers persist underneath a melt-freeze crust. The snowpack is shallow. At higher altitudes the ground is becoming increasingly bare at higher altitudes. The snowpack base is wet. Gliding movements over smooth grass-covered slopes cannot be excluded.
Tendency
Avalanche danger levels are not expected to change significantly

Avalanche Problem
Persistent weak layer
2200m
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.
Snowpack
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.
Tendency
Avalanche danger changes little. As wind intensifies by mid-week, fresh small-scale snowdrifts can accumulate.
