Fresh trigger-sensitive snowdrift accumulations generated by southerly winds
Avalanche danger above 1600m is considerable, below that altitude danger is low. Avalanches can in some places be triggered even by one sole skier. Above the treeline avalanches can fracture down to more deeply embedded layers in the snowpack, particularly on north-facing slopes. Also naturally triggered avalanches and remote triggerings are possible. Whumpf noises and cracks when you tread upon the snowpack, as well as fresh avalanche releases, are alarm signals and indicate imminent danger. Naturally triggered glide-snow and loose-snow avalanches are possible, mostly small sized releases.
Snowpack
The loosely packed fresh fallen snow from Wednesday is being transported by intensifying southerly winds and deposited on north-facing slopes atop loose surfaces. Inside the old snowpack are weak layers of faceted crystals on very steep north-facing slopes above the timberline. On very steep grass-covered sloves the entire snowpack can glide away.

Southerly winds are generating fresh, trigger-sensitive snowdrift accumulations
Avalanche danger above the timberline is considerable, below that altitude danger is low. Slab avalanches can in some places on NW/N/E facing slopes be triggered even by one sole skier. Danger zones occur esp. near ridgelines, behind protruberances in the landscape and in gullies and bowls. Size and frequency of danger zones tend to increase with ascending altitude. Danger zones are generally easily recognized. In isolated cases, avalanches can fracture down to more deeply embedded layers in the snowpack. Naturally triggered glide-snow and wet-snow avalanches are possible, the releases remain mostly small-sized.

Snowpack
Wherever snowdrifts accumulate they will be deposited atop loose fresh snowfall on shady slopes. Inside the old snowpack esp. on very steep north-facing slopes there are weak layers of faceted crystals above the timberline. On very steep grass-covered slopes the entire snowpack can glide away.
