Persistent weak layers
- Above 1,800 m
Main danger: weak old snowpack
Main danger: weak old snowpack
Avalanche danger above 1800m is moderate, below that altitude, low. Winter sports enthusiasts can in isolated cases trigger avalanches on steep shady slopes above 1800m which fracture down to deeper layers inside the snowpack, particularly where the snowpack is melt-freeze encrusted but is not capable of bearing loads. On steep grass-covered slopes, isolated glide-snow avalanches are possible despite lower temperatures. Avoid zones below glide cracks in the surface.
Above 1800m on shady slopes: weak layers occur in lowermost part of the snowpack. During a night of cloudy skies, the snowpack will freeze only poorly, after it softened up during the daytime on Saturday.
As the result of a weak cold front, temporarily heavily-cloudy-to-foggy mountain weather, with minor snowfall down to 1500-1800m. Colder than in recent days. In afternoon, improving conditions from the west, sunny intervals. Temperature at 2000m: -1 degree; at 3000m: -7 degrees. Moderate southwesterly winds at high altitudes.
Main danger: the weak old snowpack.
