Persistent weak layers
- Above 2,000 m
Still a highly unfavorable snowpack
Still a highly unfavorable snowpack
Older snowdrift accumulations can still be triggered. Marked weak layers in the old snowpack can be triggered by one single winter sports enthusiast, particularly on steep, little skied on slopes. The danger zones are not visible. Whumpf noises and fractures when treading on the surface are alarm signals. Activities in backcountry demand careful evaluation of the terrrain and assessment of the dangers.
The most recent fresh snowfall and freshly generated snowdrifts have already settled somewhat and consolidated. In higher wind-protected zones there is still loose snow or surface hoar deposited on top of a weak old snowpack, particularly on steep shady slopes. On sunny slopess and in general at lower altitudes, the snowpack is melt-freeze encrusted in many places. The snowpack on steep south-facing slopes are often capable of bearing loads.
Summits will be shrouded in clouds as of midday, light snowfall is anticipated in places. During the course of the day, W/SW winds will intensify. Temperature at 2000m: -6 to -1 degree; at 3000m: -11 to -7 degrees. Moderate-to-brisk W/SW winds at high altitudes.
As a result of some fresh snowfall and wind, avalanche danger could increase somewhat. Triggerings in the old snow are still possible.
