Avoid trigger-sensitive snowdrifts

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.

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.

On Tuesday some intermittent snowfall from dense clouds, moderate N/NE winds, 30 km/hr. At 2000m: -5 degrees; at 3000m: -10 degrees C.

Proneness of snowdrifts triggering will decrease gradually
