Caution urged on steep, shady high-altitude slopes. Beware small fresh snowdrifts.

Slab avalanches can be triggered in the old snow in some places by large additional loading. Caution is urged on very steep, shady high altitude slopes. In addition, small-sized snowdrift accumulations occur in ridgeline terrain and behind protruberances in the landscape at increasing frequency with ascending altitude, these drifts are prone to triggering. Small-to-medium sized slab avalanches can be triggered by winter sports enthusiasts. Especially on steep grass-covered slopes, small-sized glide-snow avalanches continue to be possible. Be careful beneath glide cracks.

Snowpack

The fresh fallen snow from the weekend lies deposited on top of an often moist, superficially melt-freeze encrusted old snowpack up to high altitudes. With increasing altitude, particularly in ridgeline and pass zones, as well as behind protruberances in the landscape, small freshly-generated snowdrift accumulations occur. At high altitudes, especially on shady slopes, there are faceted intermediate layers inside the snowpack. These can be triggered in some places. In high altitude ridgeline terrain, surface hoar can form.

Tendency

No significant change in the avalanche situation is anticipated.

Predominantly low avalanche danger

Avalanche danger is low. On extremely steep, especially shady slopes, small avalanches can be triggered by winter sports enthusiasts. Apart from being buried in snow masses, the risks of being swept along and forced to fall also require caution. Particularly on sunny slopes where the ground is smooth, naturally triggered small-sized, in isolated cases medium-sized glide-snow avalanches continue to be possible.

Snowpack

The most recent fresh fallen snow lies deposited on top of an often moist, superficially melt-freeze encrusted old snowpack up to high altitudes. Particularly in ridgeline zones, mostly small freshly-generated snowdrift accumulations occur. On steep grass-covered slopes, glide cracks and small-sized glide-snowslides have repeatedly been observed.

Tendency

No significant change in the avalanche situation is anticipated.
