Persistent weak layers
- Above 2,400 m
Isolated avalanche prone locations in persistent weak layer. Isolated glide-snow avalanches.
Isolated avalanche prone locations in persistent weak layer. Isolated glide-snow avalanches.
Avalanches can be triggered in the persistent weak layer in isolated cases above about 2400m on very steep shady slopes. These releases usually are small-sized. The risks of injuries from being forced to take a fall outweigh those of being buried in snow masses. As a result of daytime warming and solar radiation, isolated, generally small-sized glide-snow avalanches are still possible on steep smooth slopes which have not yet discharged. Glide cracks are signals of possibly imminent danger.
During a night of star-studded skies during which outgoing radiation will function to perfection, a breakable-to-capable of bearing loads crust can be generated once again. During the course of the day, it softens up particularly on sunny slopes and at lower altitudes. On shady high-altitude slopes above 2400m, isolated weak layers occur inside the snowpack.
Sunshine will be dominant into the afternoon, then widespread clouds will move in from the south. Temperatures will quite mild, due to foehn impact. At 2000m: +6 degrees. Moderate (in high alpine regions gradually brisk-velocity) southwesterly winds.
As a result of foehn winds in the southern regions on Tuesday, heavily clouded skies, little sunshine. Ongoing low avalanche danger.
