Avalanche prone locations in old snow on shady sides.

Avalanche prone locations in old snow on shady sides.

Avalanche danger above 2200m is moderate, below that altitude danger is low. Weak layers in the old snowpack are the main problem. Slab avalanches can trigger especially by large additional loading and in transition from shall to deep snow. Danger zones occur in steep ridgeline terrain above 2200m, in particular in shady aspects, near ridgelines, in very steep high terrain where medium-sized avalanches cannot be ruled out. Isolated smaller glide-snow avalanches can trigger naturally on steep grass-covered slopes and rock plates where there is sufficient snow on the ground.

Snow on the shady side is still dry and expansively metamorphosed at the surface. A layer consisting of faceted crystals formed in some places with wind crusts in high altitude terrain on the shady side. With ascending altitude an increasing number of layers consisting of faceted crystals persists also under older snowdrift accumulations at high altitude. At low altitudes the snowpack is shallow, moist down to the ground. Gliding movements over smooth grass-covered slopes are possible.

On Thursday, avalanche danger will change little.
