Persistent weak layers
- Above 2,400 m
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, 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. South-facing slopes are becoming increasingly bare of snow up to high altitudes. On shady high-altitude slopes above 2400m, isolated weak layers occur inside the snowpack.
Tranquil mountain-climbing and skiing weather without perturbances. The zero-degree level will lie at 2600-2800m. Skies will frequently be cloudless and brilliantly sunny. The dry air will ensure outstanding visibility. Temperature at 2000m: up to +5 degrees. Mostly light predominantly southwesterly winds at high altitude.
Little change expected
