Avalanche Activity

Wet-snow + glide-snow avalanches expected in daytime cycle at low and intermediate altitudes. Snowdrifts at high altitude still trigger-sensitive.

Main problem: the snowdrift accumulations of the last few days. Above the treeline they can be triggered as a medium-sized slab avalanche particularly by large additional loading. Avalanche prone locations are found in steep NW/E/S facing slopes and in wind-loaded gullies and bowls, as well as behind protruberances in the landscape. The tend to increase in frequency and size with ascending altitude. In isolated spots at high altitude, avalanches can also grow to large size if more deeply embedded layers are also triggered.In addition, increasingly frequent activity of wet-snow loose avalanches and slab avalanches which trigger naturally. In isolated cases, glide-snow avalanches can trigger naturally on smooth, steep grass-covered slopes in all aspects. Avalanches can be small, medium-sized. At high altitudes, large-sized releases cannot be ruled out. Zones below glide cracks should be avoided.

Snowpack Structure

Clear nocturnal skies on Monday night will make the moist snowpack surface freeze to form a melt-freeze crust. This will then soften during the day on Tuesday and the snowpacl will forfeit its firmness. Also the base of the snowpack is moist-to-wet at low to intermediate altitudes, which furthers gliding movement of the snowpack. Snowdrifts of recent days are bonding increasingly well with the snowpack, due to the warmth. Trigger-sensitive layers of expansively metamorphosed (faceted) crystals are evident in some places aboe 1600 m near crusts and, at high altitudes, at ground level. The crusts also tend to serve as water-preserving layers.

Tendency

The danger of dry-snow slab avalanches will continue to diminish. The wet-snow problem will persist.
