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 are usually small-sized. The risks of injuries from being forced to take a fall outweigh those of being buried in snow masses. Continuing isolated, usually small-sized glide-snow avalanches are still possible on steep slopes which have not yet discharged. Glide cracks are signals of possibly imminent danger.
Tonight once again a breakable-to-capable of bearing loads crust can be generated. During the daytime it softens up particularly on sunny slopes and at lower altitudes. On south-facing slopes, the ground is becoming bare of snow up to high altitudes. On shady slopes at altitudes above 2400m, isolated weak layers occur inside the snowpack.
On Tuesday, strong-velocity foehn winds will arise. Conditions will remain dry, with a mixture of weak sunshine and far-reaching high-altitude cloudbanks. Heavily clouded skies will dominate all day long. In the evening, foehn winds will slacken off. Temperature at 2000m: up to +6 degrees. Strong-velocity southlerly winds, blowing at storm strength in the foehn-exposed lanes.
As a result of perturbances, heavily clouded skies but with very little precipitation. Ongoing low avalanche danger.
