Often favorable conditions but caution urged on shady steep high altitude slopes
At high altitudes, avalanche danger is moderate. Isolated danger zones occur particularly on steep shady slopes where the snow is shallow and in transitions from shallow to deep snow. Small-to-medium triggerings are generally possible by large additional loading. Freshly generated snowdrift accumulations can be triggered by one sole skier; they are generally small releases, easily recognizable and should be cirvumvented in steep terrain. In steep grass-covered terrain, particularly on sunny slopes, generally small-sized glide-snow avalanches are possible. Caution urged below glide-cracks.
The snowpack has settled well and consolidated increasingly. On shady slopes the snowpack at high altitudes has expansively metamorphosed. At lower altitudes on shady slopes, surface hoar has formed. Steep sunny slopes have a melt freeze crust up to high altitudes. Caution: on high-altitude, usually shady slopes near ridgelines, freshly generated snowdrifts are prone to triggering. In addition, weak layers near ground level at high altitudes and faceted intermediate layers inside the old snowpack can often be triggered.
Clouds will accumulate. During the morning hours, the lower border of the cloudbanks will still be above summit level, in the afternoon the peaks will become shrouded in fog. Towards evening, snowfall will set in. During the nocturnal hours the snowfall will temporarily be heavy. At 2000m: dropping from 0 to -4 degrees. Strong-to-storm strength W/SW winds at high altitudes.
