Snowdrifts often still prone to triggering at high altitudes
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 are becoming moist on steep sunny slopes, often wind crusts. On steep sunny slopes a melt-freeze crust is evident. Encrusted snowpack surfaces moisten during the day.
Tranquil mountain weather without perturbances from early until late. In the Rhine Valley there is a sea of fog, but the sky is cloudless. Light northerly wind, and not cold. At 2000m: +1 degree. Light winds from variable directions at high altitudes.
Avalanche danger levels will decrease further
