Stability: poor · Frequency: few
Slightly rising avalanche danger above the treeline due to fresh snow and wind.
Above the treeline, fresh, mostly small snowdrift accumulations require caution. Isolated danger zones for small avalanche triggerings (slides) in steep terrain 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.
By Sunday evening, 5-10cm of fresh snow is anticipated which will be transported by winds. It will fall on a mostly bare ground, at higher altitudes atop a well-bonded and mostly wind-impacted shallow snowpack surface. Above the treeline, paricularly in ridgeline and pass areas, fresh, mostly small snowdrifts masses prevail.
In the evening, rainfall and snowfall, intermittently heavy. Snowfall level will descend to nearly 600m. Nighttime skies will be largely dry. Sunday will be cloudy all day long, low lying clouds and fog will prevail, and light snowfall will be far-reaching, with uncertain amounts. Temperature at 2000m: -7 degrees. High altitude winds: at moderate velocity from north to east.
Currently, no significant change is expected.
