Caution: freshly generated snowdrift accumulations prone to triggering in places
Due to brisk W/NW winds, snowdrift accumulations will be generated esp. in high-altitude ridgeline and pass areas which are prone to triggering (but small). Danger zones tend to increase in frequency with ascending altitude. Older snowdrift accumulations are often still prone to triggering, can be released by one sole skier and reach medium size. Snowdrift accumulations in steep terrain should be evaluated with great caution. The danger of small, in isolated cases medium-sized glide-snow avalanches is still difficult to assess. Caution urged below glide cracks.
The W/NW winds will transport the loose snow over the course of the day. Fresh and older snowdrift accumulations are often prone to triggering. Esp. on shady slopes, in wind-protected zones at high altitudes and on east-facing slopes, the snowdrifts have been deposited atop a loosely-packed snowpack surface. On sunny slopes the fresh snow is already bonded.
Gray skies. The NW high-altitude air current will bring widespread cloudbanks above the summits, only intermittent bright intervals are expected. During the daytime, clouds will descend, later on some minor snowfall is possible. At 2000m: -2 degrees. High altitude brisk W/NW winds.
Avalanche danger levels will slowly recede.
