Danger level


Avalanche Problem
Wind slab


Circumvent small-area snowdrift accumulations

Avalanche danger is low. Slabs, mostly small-sized, can trigger particularly on very steep and extremely steep north, northwest and south-facing slopes by minimum additional loading. Isolated small glide-snow and loose-snow avalanches can trigger naturally. Danger zones occur on very steep and extremely steep slopes, in entries into gullies and bowls and behind protruberances in the landscape. Danger zones difficult to recognize due to poor visibility.

Snowpack

On top of a shallow and relatively compact snow cover, snow and drifts (with embedded graupel) lie deposited. During the night, surface hoar can form. In wind-protected terrain, loose fresh snowfall still lies on the surface. The border to the old snowpack can serve as a weak layer, m deeply embedded layers are unlikely to trigger.

Evaluate snowdrifts and persistent weak layer problem with great caution

Avalanche danger above 2000m is MODERATE, below that altitude danger is low. On NW/N/S facing slope small-to-medium slab avalanches can be triggerd by minimum additional loading in places, higher up also on south-facing slopes. The snowdrift accumulations are generally easy to recognize, danger zones occur mostly near ridgelines and behind protruberances in the landscape. Size and frequency of danger zones tend to increase with ascending altitude. As of 2300m, releases can fracture down to more deeply embedded layers inside the snowpack and grow to larger size. Small glide-snow and loose-snow avalanches can trigger naturally.

Snowpack

The snow cover has below average depths, is highly irregular and the layering is rather poor. In wind-protected zones, increasingly frequent crusts with immediately adjacent faceted crystals are evident, sometimes with blanketed surface hoar. With ascending altitude there are weak layers of faceted crystals evident between crusts.

Snowdrift accumulations prone to triggering

Avalanche danger above 2000m is MODERATE, below that altitude danger is low. Slabs, mostly small-sized, can be triggered even by minimum additiional loading both near to and distant from ridgelines and behind protruberances in the landscape on north, northwest and south facing slopes. If they fracture down to more deeply embedded layers in the snowpack the releases can grow to medium size. Snowdrifts hard to recognize due to poor visibility.

Snowpack

On top of a shallow and relatively compact snow cover, snow and drifts lie deposited. Overnight, surface hoar can form. In wind-protected terrain the fresh snow is still very loosely-packed, winds have generated a bonded slab. The border to the old snowpack and loosely-packed snow inside the snowdrifts can serve as a weak layer, more deeply embedded weak layers are triggerable only in isolated cases.
