Persistent weak layers
- Above 2,200 m
Caution urged on steep, shady high-altitude slopes. Beware fresh snowdrifts.

Slab avalanches can be triggered in the old snow in some places with large additional loading. Caution is urged on very steep, shady high altitude slopes. In addition, small-sized snowdrift accumulations can be triggered in ridgeline terrain and behind protruberances in the landscape with increasing frequency at ascending altitudes, the drifts are prone to triggering. Small-to-medium sized slab avalanches can be triggerred by winter sports enthusiasts. Especially on steep grass-covered slopes, small-sized glide-snow avalanches continue to be possible. Be careful beneath glide cracks.
Only small amounts of snowfall are being registered, deposited on top of a moist, superficially melt-freeze encrusted old snowpack surface up to high altitudes. With increasing altitude, particularly in ridgeline and pass zones, as well as behind protruberances in the landscape, small freshly-generated snowdrift accumulations occur. At high altitudes, especially on shady slopes, there are faceted intermediate layers inside the snowpack. These can be triggered in some places. There is still inadequate information available from off-piste terrain to the Avalanche Warning Service.
Predominant sunshine and good visibility in the mountains accompanied by a slight tendency towards foehn winds arising. Temperatures at 2000m: -4 to -1 degree. High-altitude winds: light W/SW winds, blowing at moderate to brisk strength in the foehn-exposed zones.
Avalanche danger is not expected to change significantly.
