Persistent weak layers

Mild persistent weak layer problem
Mild persistent weak layer problem
Avalanche danger is low. Weak layers persist in the old snowpack. Small slab avalanches can be triggered in particular by large additional loading. Avalanche prone locations occur at transitions from shallow to deep snow in extremely steep shady terrain
The snowpack is largely stable. Only on shady side slopes at higher altitudes are there still weak layers consisting of faceted crystals embedded in the middle part of the snowpack close to melt-freeze crusts, triggerable only in isolated cases. Where there is still snow on sunny slopes a nocturnal melt-freeze crust forms which softens during the course of the day. The snow on shady side slopes is powdery. Particularly in the zones where inversion conditions prevail, easterly winds will intensify. During the course of the day, shallow snowdrifts can accumulate. The snowpack fundament is often moist.
Avalanche danger levels not expected to change significantly.
