Persistent weak layers
- Above 2,200 m
Caution urged on steep, shady high-altitude slopes
The fresh fallen snow and small-sized snowdrift accumulations from the last few days are settling increasingly and firming up. At heightened altitudes they were often deposited on top of faceted layers of old snow from late autumn. The bonding is poor in places. Older snowdrift accumulation can still be triggered in some places.
A slight tendency of foehn winds on Sunday, sunny in the morning hours followed by widespread thin cloudbanks. In the afternoon it will turn gloomy, a few snowflakes are expected as evening nears. Temperature at 2000m: 0 degrees. High-altitude winds: moderate to brisk from south to southwest.
The persistent weak layer remains prone to triggering on high-altitude, steep shady slopes.
Caution urged on steep, shady high-altitude slopes
Slab avalanches can be triggered in the old snow. Caution is urged on very steep, shady high altitude slopes. Small-sized snowdrift accumulations can be triggered with increasing frequency at ascending altitudes. Medium-sized slab avalanches can be triggerred by winter sports enthusiasts. Especially on steep grass-covered slopes, small-to-medium sized glide-snow avalanches continue to be possible. Be careful beneath glide cracks.
