Persistent weak layer is difficult to recognize

Avalanche danger above 1800m is moderate, below that altitude danger is low. Weak layers in the old snowpack are the main problem. Slab avalanches can trigger even by the weight of one single person. Danger zones occur in steep ridgeline terrain especially in shady aspects, near ridgelines, in steep high altitude terrain and in transitions from shallow to deep snow. Depending on the depth of the snow cover where the winds of recent days have consolidated the upper snow like a slab, medium sized avalanches are possible. Isolated glide-snow avalanches can trigger naturally at any time of day or night, particularly on south-facing steep grass-covered slopes at intermediate altitudes where there is sufficient snow on the ground. They can grow to medium size.

Snowpack

Mild temperatures have helped the snowpack to settle and consolidate. Powder or wind-impacted snow has been generated in ridgeline terrain at high altitudes on north-facing slopes. On sunny slopes, the snowpack surface becomes moist on sunny slopes, during the nighttime hours a melt-freeze crust forms. At high altitudes, there are intermediate layers of faceted crystals and graupel. At low altitudes the snowpack is moist down to the ground. Gliding movements over smooth grass-covered slopes cannot be excluded.

Tendency

Avalanche danger levels will further diminish in the good weather and mild temperatures.

Beware of injuries through unwelcome contact with the ground and forced falls

Avalanche danger is low. Weak layers in the old snowpack are the main problem. Slab avalanches can trigger even by the weight of one single person. Danger zones occur in steep ridgeline terrain especially in shady aspects, near ridgelines, in steep high altitude terrain and in transitions from shallow to deep snow. Avalanches are mostly small, the risks of falling outweigh those of being buried in snow masses. Isolated glide-snow avalanches can trigger naturally at any time of day or night where there is sufficient snow on the ground.

Gliding snow on steep grass-covered slopes

Avalanche danger 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. Danger zones occur in steep ridgeline terrain especially in shady aspects, near ridgelines, in steep high altitude terrain and in transitions from shallow to deep snow, depending on the depth of the snow cover where the winds of recent days have consolidated the upper snow like a slab, medium sized avalanches are possible. Gliding snow requires high attentiveness. Glide-snow avalanches can trigger naturally at any time of day or night, particularly on south-facing steep grass-covered slopes at intermediate altitudes, in some places in shady terrain near the forest rims. They can grow to medium size.

At high altitudes, there are intermediate layers of faceted crystals and graupel. At low altitudes the snowpack is moist down to the ground. Gliding movements over smooth grass-covered slopes have been observed increasingly frequently.

Tendency

Avalanche danger levels will diminish further.
