Wet slides and small glide-snow avalanches

Wet slides and small glide-snow avalanches

In zones where there has been rain impact, wet slides and small-sized glide-snow avalanches are possible. Caution urged below glide cracks. Fresh and older snowdrift accumulations can be triggered even by one sole skier. Danger zones occur particularly in steep shady terrain, in wind-loaded gullies and bowls and behind protruberances in the landscape. Size and frequency of danger zones tend to increase with ascending altitude.

The snowpack was moistened and weakened up to high altitudes by rainfall. Some naturally triggered glide-snow fractures and wet-snow avalanches have been observed. Following the receding rainfall clouds in the afternoon, the danger of wet-snow avalanches will decrease somewhat. Stormy foehn winds will continue to transport the fresh and loose snow, forming trigger-sensitive snowdrift accumlulations, these lie deposited at high altitudes particularly on shady slopes atop softened layers. Also inside the snowdrifts themselves are trigger-sensitive intermediate layers. On sunny slopes the bonding to the old snowpack surface is better.

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.

Avalanche danger levels not expected to change significantly
