Persistent weak layer at high altitudes
Avalanche danger above 1800m is moderate. Weak layers in the old snowpack are the main problem Slab avalanches can be triggered even by the weight of one sole person, particularly by large additional loading. Danger zones occur in steep ridgeline terrain especially in shady aspects, near ridgelines, in steep high altitude terrain and in shallow snow. Avalanches can grow to medium size. In addition, gliding snow requires high attentiveness. Glide-snow avalanches can trigger naturally at any time of day or night, particularly on sunny steep grass-covered slopes, in some places in shady terrain near the forest rims. and on rock plates. At high altitudes they can reach medium size.
The snowpack has settled and consolidated. At night, a breakable crust forms on south-facing slopes, then softens during the daytime. Dry snow is to be found on shady slopes. At high altitudes, there are isolated layers of faceted crystals. 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.
Avalanche danger levels will diminish further
