Avalanche danger above 2200m is HIGH, below that altitude danger is considerable. The situation is dangerous for winter sports enthusiasts, slab avalanches can be triggered by minimum additional loading and grow to medium size, also isolated naturally triggered avalanches from ridgeline snowdrifts are possible. Near-surface slab avalanches in fresh snow and drifts can fracture down to deeper layers above 2200m on W/N/E-facing slopes and grow to large size. Due to solar radiation in afternoon hours, naturally triggered loose-snow avalanches can be expected. Avalanches released at higher altitudes can fracture down to deeper layers and then plummet down to green zones. Especially above the timberline, small-to-medium glide-snow avalanches can trigger naturally in very steep grass-covered terrain.
Snowpack
Since Friday evening 50-100cm of fresh snow has been registered at high altitudes. By Tuesday midday another 20-30cm is anticpated. Inside the fresh snow and snowdrifts there are soft layers of loose snow or graupel. In the lower and middle parts of the snowpack above 2200m there are weak layers of faceted crystals which are embedded between cdrusts. Below 2000m the old snow is moist.
Tendency
As the snow settles the trigger-sensitivity of weak layers of fresh snow and drifts will gradually diminish

Unfavorable avalanche situation
Avalanche danger above the treeline is CONSIDERABLE, below that altitude danger is moderate. Avalanches can in some zones be triggered by one sole skier, esp. in the afternoon, and grow to medium size, esp. on steep leeward slopes. Snowdrift accumulations are blanketed , often difficult to recognize. Avalanche releases mostly medium-sized, in isolated cases large-sized. On extremely steep slopes, naturally triggered loose-snow avalanches can be expected. Medium sized glide-snow avalanches can trigger naturally in very to extremely steep grass-covered terrain.
Snowpack
Since Friday evening 50-80cm of fresh snow has been registered at high altitudes. By Tuesday midday another 15-30cm is anticpated. Inside the fresh snow and snowdrifts there are soft layers of loose snow or graupel. In the lower and middle parts of the snowpack above 2200m there are weak layers of faceted crystals which are embedded between cdrusts. Below 2000m the old snow is moist. Over ground which previously was bare of snow the fresh fallen snow can glide away as a glide-snow avalanche.

Likelihood of snowdrifts triggering will decrease slightly

Avalanche danger above the treeline is considerable, below that altitude danger is moderate. Slab avalanches can be triggered by minimum additional loading and grow to medium size, also isolated naturally triggered avalanches from ridgeline snowdrifts are possible. Near-surface slab avalanches in fresh snow and drifts can fracture down to deeper layers above 2200m on NW/N/E-facing slopes and grow to large size. Especially above the timberline, small-to-medium glide-snow avalanches can trigger naturally in very steep grass-covered terrain and grow to medium size.

Avoid trigger-sensitive snowdrifts
Avalanche danger above the treeline is moderate, below that altitude danger is low. Avalanches can in some zones be triggered by one sole skier, and grow to medium size. Danger zones occur on north-facing slopes above 2200m. Snowdrift accumulations are occur often distant from ridgelines, behind protruberances in the terrain and in gullies and bowls. Medium sized glide-snow avalanches can trigger naturally in very to extremely steep grass-covered terrain.Avalanche danger is moderate. Small-to-medium glide-snow avalanches can trigger naturally on extremely steep grass-covered slopes. On extremely steep slopes, naturally triggered loose-snow avalanches can be expected.
Snowpack
Since Friday evening 30-50cm of fresh snow has been registered accompanied by lots of win. Inside the fresh snow and snowdrifts there are soft layers of loose snow or graupel. In the lower and middle parts of the snowpack above 2200m there are weak layers of faceted crystals which are embedded between crusts. Below 2000m the old snow is moist, has often formed a crust.
Tendency
Proneness of snowdrifts triggering will decrease gradually
