Hidden persistent weak layer problem

Hidden persistent weak layer problem

Avalanche danger above 2200m is moderate, below that altitude danger is low. In few places, an avalanche can be triggered by one sole skier as a slab avalanche. Danger zones are nearly impossible to recognize, most critical behind protruberances in the landscape and in gullies and bowls. Fresh drifts on some ridgeline slopes can be easily triggered as a small slab. The wind-loaded zones are easily recognized, watch out for the risks of falling. On very steep sunny slopes, small loose-snow avalanches are possible. Isolated small naturally triggered glide-snow avalanches are possible.

Atop a hardened crust (or else, bare ground) 10-30 cm of loosely-packed snow lie deposited, often wind impacted. On shady slopes at high altitudes the fresh snow from Friday has also been deposited atop loose snow or surface hoar. The fundament on steep shady slopes at high altitudes is expansively metamorphosed.

On Sunday, widespread and dense cloudbanks will cover the sky, but the summits will remain mostly in the clear. In the afternoon hours in the Northern Alps, minor snowfall is possible. A cold, light-to-moderate northerly wind will be blowing. At 2000m: -7 to -4 degrees; at 3000m: -12 to -9 degrees.

No significant change in danger levels anticipated
