Persistent weak layers
- Above 2,000 m
Snowdrifts often still prone to triggering at high altitudes
Tranquil mountain weather without perturbances from early until late. In the Rhine Valley there is a sea of fog, but the sky is cloudless. Hardly any wind, and not cold. At 2000m: 0 degrees. Light winds from variable directions at high altitudes.
Avalanche danger levels will decrease further
Snowdrifts often still prone to triggering at high altitudes
In some places avalanches can be triggered by one sole skier, mostly medium-sized releases. Danger zones tend to increase in frequency with ascending altitude, particularly on steep shady slopes, but also behind protruberances in the landscape. Activities in backcountry demand much experience in assessing dangers and defensive conduct. At lower altitudes, danger is moderate. In addition, on very steep grassy slopes, small-to-medium glide-snow avalanches can trigger naturally.
The snowpack was able to settle and consolidate somewhat due to higher temperatures and solar radiation. Particularly on shady slopes in the uppermost part of the snowpack there are weak layers evident which can easily be triggered. During the course of the day, superficially melt-freeze encrusted layers aer becoming moist on steep sunny slopes. The gliding snow activity has intensified somewhat over the last few days.
