Avalanche danger is moderate. . On extremely steep slopes, naturally trigger avalanches of medium size are expected due to daytime warming and solar radiation. On steep grass-covered slopes, medium-sized glide-snow avalanches are to be expected Avalanches in blanketed snowddrifts can be triggered even by one sole skier and reach medium size, esp. on steep shady slopes. Drifts are hard to recognize due to the fresh snow blanketing them. On very steep grass-covered terrain glide-snow avalanches can release and grow to medium size.
Snowpack
Since Friday evening 50-80cm of fresh snow has been registered at high altitudes. Due to daytime warming the snowpack is rapidly settling. 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, esp on W/S/E facing slopes above 2400m. 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.
Tendency
Likelihood of snowdrifts triggering will decrease slightly, wet-snow problems will increase, wet-snow problems will increase

Snowdrift accumulations still prone to triggering but difficult to recognize
Avalanche danger above 2000m is CONSIDERABLE, below that altitude danger is moderate. Avalanches can in some zones be triggered in the blanketed snowdrifts by one sole skier, esp. on shady 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 80-120cm of fresh snow has been registered at high altitudes. Due to daytime warming the snowpack is rapidly settling. 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, esp on W/S/E facing slopes above 2400m. 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.

Assess with caution trigger-sensitive snowdrift accumulations
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 wind. Inside the fresh snow and snowdrifts there are soft layers of loose snow or graupel, and also in transitions to the old snow. On north-facing slopes 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, wet-snow problems will increase

Backcounry tours demand a defensive route selection
Avalanche danger above 2000m is considerable, below that altitude danger is moderate. Slab avalanches can be triggered by minimum additional loading and grow to medium size. Esp. on W/N/E-facing slopes above 2200m, avalanches can fracture down to more deeply embedded layers of the snowpack and grow to large size. On extremely steep slopes, naturally trigger avalanches of medium size are expected due to daytime warming and solar radiation. On steep grass-covered slopes, medium-sized glide-snow avalanches are possible.
Snowpack
Since Friday evening 70-120cm of fresh snow has been registered at high altitudes. Due to daytime warming the snowpack is rapidly settling. 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, esp on W/S/E facing slopes above 2400m. 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.
Tendency
As the snow settles the trigger-sensitivity of weak layers of fresh snow and drifts will gradually diminish, wet-snow problems will increase
