Caution: freshly generated snowdrift accumulations
Avalanche danger is often low, moderate at high altitudes. In some places the snowpack evidences weak layers, particularly on very steep shady slopes. Most small (in isolated cases medium) avalanches are triggered by large additional loading. Freshly generated snowdrift accumulations can be triggered by one single skier. Most are small, easily recognized and should be circumvented 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. During nights with clear skies, the snowpack surface on steep shady slopes 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: in high-altitude, mostly shady terrain, there are freshly generated snowdrifts near ridgelines which are prone to triggering.
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.
