Beware fresh snowdrift accumulations

Beware fresh snowdrift accumulations

Avalanche danger above 1800 m is moderate, below that altitude danger is low. Fresh snowdrift accumulations in wind-loaded gullies and bowls on N/E/SE facing slopes can be triggered as medium avalanches by 1 person. Beware: acute danger of falling. Glide-snow avalanches are a threat up to summit level. Where there is sufficient snow on the ground, large-sized releases are possible, though most are small-to-medium. Avoid zones below glide cracks. On very steep sunny rough and rocky slopes, small loose-snow avalanches can trigger naturally.

Up to 1800 m, up to summits on sunny slopes, the fresh snowdrifts were deposited atop a melt-freeze crust capable of bearing loads. Weak layers occur inside the fresh drifts. In addition, on shady slopes above 1800 m the loose old snowpack surface is a potential weak layer for slab avalanches. The snowpack base is moist-to-wet up to high altitudes, can glide esp. over steep grass-covered slopes.

On Friday evening, clouds will disperse, the nocturnal skies will be cloudless. On Saturday, unhindered sunshine. Brisk NW winds, gusts up to 60 km/hr. At 1500 m: 1-4 degrees; at 2000 m: -1 to +1 degree.

The snowdrift problem will continue to diminish, the gliding snow problem will persist.
