Main danger: fresh snowdrifts and weak layers in the old snow
Main danger: fresh snowdrifts and weak layers in the old snow
Latest snowdrift accumulations are prone to triggering, especially on wind-protected shady slopes. Danger zones are located mostly at high altitudes and in foehn lanes. Also, above 2400 m on steep shady slopes there are unfavourable layers in the old snowpack. Settling noises, glide. cracks are signals of danger. As a result of daytime warming and solar radiation, small-to-medium wet-snow and glide-snow avalanches are possible, particularly on shady slopes below 2000 m, and on sunny slopes below 2400 m
The windy, mild conditions continue. Amid intermittently strong SW winds, fresh snowdrift accumulations have repeatedly been generated over the last few days and are prone to triggering. With solar radiation and daytime warming the snowpack on very steep sunny slopes is weakened over the course of the day. On steep sunny slopes a breakable melt-freeze crust has formed. Particularly on shady slopes above 2200 m the snowpack layering is unfavourable. These danger zones are not visible to the naked eye. The generally shallow snowpack is moist up to intermediate altitudes. Skiing tours and descents in outlying terrain below the timberline, often below 2000 m, are unrewarding due to the lack of snow. At low altitudes there is often no snow on the ground.
Sunday night: it will remain dry, foehn-impacted, slightly cloudy. Monday: clouds will pass through but sunshine will predominate. Zero-degree level nearly at 3000 m: very mild, but temperatures will start to drop in the afternoon. In foehn-lanes very windy. At 2000 m: 2-7 degrees. Moderate SW winds, stronger in the foehn-lanes.
A weak cold front on Tuesday will bring gray skies. Above 1500 m, minor snowfall. Danger of dry-snow avalanches not expected to change significantly. Danger of wet-snow avalanches will diminish as temperatures drop.
