Persistent weak layers
- Above 2,200 m
Caution urged in steep shady terrain seldom skied on

In some places avalanches can be triggered by one sole skier, generate small-to-medium sized releases, mostly above 2200m in transitions from shallow to deeper snow, e.g. at entry points into gullies and bowls. Danger zones tend to increase in frequency with ascending altitude. Activities in backcountry demand cautious route selection, particularly in shady steep terrain seldom skied on. In isolated cases small glide-snow avalanches are possible. Caution urged below glide cracks. Due to daytime warming and solar radiation, increasingly frequent loose-snow slides are possible, particularly on steep sunny slopes. Caution urged below glide cracks.
The snowpack was able to consolidate up to high altitudes. Particularly on shady slopes there are weak layers evident which can easily be triggered. Snowpack surfaces are often powdery on shady, wind-protected slopes. Elsewhere there are wind crusts and a melt-freeze crust evident. Encrusted snowpack surfaces on steep sunny slopes moisten during the day.
Nocturnal skies will be densely cloudy. On Friday, dense layers of cloud cover will generate diffuse light conditions, but most summits will remain in the clear. Foehn-induced southerly air current will bring a few bright intervals in the afternoon. At 2000m: 0 degrees. Moderate to brisk S/SW winds.
Avalanche danger levels will decrease further
