Caution: freshly generated snowdrift accumulations
Additional trigger-sensitive snowdrift accumulations are forming due to strong-to-stormy W/SW winds. The accumulations can be easily triggered even by one sole skier. Danger zones occur also distant from ridgelines 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. Glide-snow avalanches, mostly small, continue to be possible. Caution urged below glide cracks.
Through 10-20 cm of fresh snowfall plus strong-to-storm strength W/SW winds, further trigger sensitive snowdrift accumulations will be generated. Also older accumulations can be triggered. Inside the drifts themselves, they are often trigger-sensitive intermediate layers. As temperatures drop, the danger of wet-snow avalanches has decreased, but glide-snow avalanches continue to be possible.
Stormy winds! High-altitude cloudbanks will pass through, hamper the sunshine intermittently, often noticeably. Mild: zero-degree level at 2700m at midday. At 2000m: 0 to +4 degrees. Storm S/SW winds at high altitude.
Snowdrift accumulations which are prone to triggering are being ongoingly generated by fresh fallen snow and strong-to-storm strength winds, including heavy storm gusts from the west.
