Persistent weak layers
- Above 1,800 m
Caution esp. at transitions from shallow to deep snow!
Caution esp. at transitions from shallow to deep snow!
Avalanche danger above 1800 m is moderate, below that altitude danger is low. Main problem: weak old snow. In places, medium-sized slab avalanches can be triggered even by minor additional loading. Avalanche prone locations occur primarily in very steep terrain in W/N/E aspects. Frequency and size increase with ascending altitude. In addition, on very steep slopes with smooth ground below 2000 m small glide-snow avalanches can trigger naturally in all aspects. Avoid stopping or staying below glide cracks.
A few centimeters of new snow cover the snowdrifts of the last few days. Weak layers embedded in older snowdrift accumulations have consolidated. In particular at high altitudes the middle part of the snowpack contains weak layers consisting of faceted crystals. Nocturnal melt-freeze crusts will form on sunny side slopes. At intermediate altitudes the snowpack base is frequently wet. As a result, the snowpack will start gliding over smooth ground.
No significant change of avalanche danger anticipated.
