Evaluate critically fresh and older snowdrift accumulations
Avalanche danger above the timberline is moderate, danger below that altitude is low. Fresh and older snowdrift accumulations can be triggered even by one sole skier. Danger zones occur particularly on steep shady slopes, in wind-loaded gullies and bowls, and behind protruberances in the terrain. Size and frequency of danger zones tend to increase with ascending altitude. The snowdrifts are often blanketed, making them difficult to recognize. On steep grass-covered slopes, particularly in sunny aspects, small glide-snow avalanches are posible. Caution urged below glide-cracks.
Snowpack
On Thursday night, 15-25 cm of fresh snow was registered, often transported by strong-velocity W/NW winds. The fresh snow and drifts were deposited atop an unfavorable, expansively metamorphosed old snowpack surface, often atop surface hoar, on shady slopes in particular. Also inside the snowdrifts themselves there are frequently trigger-sensitive intermediate layers evident. On sunny sloppes, bonding to the old snowpack surface is better.

Snowpack
On Thursday night, 15-25 cm of fresh snow was registered, in the Silvretta 10-20 cm, often transported by strong-velocity W/NW winds. The fresh snow and drifts were deposited atop an unfavorable, expansively metamorphosed old snowpack surface, often atop surface hoar, on shady slopes in particular. Also inside the snowdrifts themselves there are frequently trigger-sensitive intermediate layers evident. On sunny sloppes, bonding to the old snowpack surface is better. At high altitudes, weak layers near the ground and faceted intermediate layers inside the old snowpack can often be triggered.
