Fresh and older trigger-sensitive snowdrift accumulations are threatening. The accumulations can be easily triggered even by one sole skier. Danger zones occur in wind-loaded steep terrain, in gullies and bowls, and behind protruberances in the landscape. Size and frequency of danger zones tend to increase with ascending altitude. In addition, on steep shady slopes at high altitudes and in transitions from shallow to deep snow, isolated slab avalanches can be triggered by large additional loading. In zones where there has been rain impact, slides and small wet-snow avalanches are possible. Glide-snow avalanches, mostly small, continue to be possible. Caution urged below glide cracks.
Snowpack
Another 5-10 cm of fresh snow is anticipated, locally more. This and the fresh snowfall from Thursday will be transported at high altitudes. Further fresh snowdrift accumulations will be generated, which then blanket older accumulations of drifts. Fresh snow and snowdrift accumulations are not well bonded with the old snowpack and its melt-freeze crusts, often with embedded layers of graupel. Deeper layers in the old snowpack are generally compact and unlikely to trigger, mostly likely in places where the snow is shallow on very steep shady slopes.

Fresh snowdrift accumulations remain prone to trigger at high altitudes

Small-sized snowdrifts require caution
Avalanche danger at high altitudes is moderate, danger below that altitude is low. In ridgeline terrain, in gullies and bowls, freshly generated snowdrift accumulations require high caution. They are mostly small-sized, but poorly bonded with the old snowpack and thus, prone to triggering, small - in isolated cases medium-sized - avalanches can be triggered by one sole skier. Danger of glide-snow avalanches still persists, but diminished due to lower temperatures.
Snowpack
Only a few cm of fresh snowfall, to be transported at high altitudes together with the fresh snow from Thursday. Fresh snowdrifts will accumulate. The latest batch of fresh snow lies deposited atop a well-consolidated, often melt-freeze encrusted old snowpack, following a period of lower temperatures. Only isolated small glide-snow avalanches possible.
Tendency
No significant change expected in avalanche danger levels.
