Caution urged towards small-sized snowdrifts
Above the treeline, fresh, mostly small snowdrift accumulations require caution. Isolated danger zones for small avalanche triggerings (slides) in steep terrain and freshly wind-loaded slopes are possible. Avalanche headquarters currently has little data from outlying regions about the snowpack, for that reason a cautious on-site evaluation is important. Below the treeline, no marked avalanche problem is evident.
The latest round of fresh snowfall was deposited atop a well consolidated old snowpack surface showing marked effect from the wind. Knolls and ridges are often totally windblown or have only a bit of fresh snow, gullies and bowls have noticeably more snow. With increasing altitude, particularly in pass and ridgeline areas, mostly small-to-medium snowdrift accumulations are evident.
During the morning at high altitudes, heavy clouds will pass through from the east, high-fog will extend up to about 1000m. In the afternoon, more sunshine. It will remain cold. At 2000m: -6 to -2 degreees. Light to moderate E/NE winds at high altitudes.
Currently no significant change is expected.
