    • Above 2,000 m

Avalanche Activity

Snowdrift accumulations still trigger-sensitive, esp. on steep shady slopes at high altitude

Avalanche danger above the timberline is MODERATE, below that altitude danger is low. In all aspects, small-to-medium slab avalanches can be triggerd by minimum additional loading in places. Danger zones occur mostly near ridgelines and behind protruberances in the landscape, esp. on W/N/NE facing slopes, caution also urged near treelines and in forest clearances. Size and frequency of danger zones tend to increase with ascending altitude. Above 2000m, releases can fracture down to more deeply embedded layers inside the snowpack and grow to larger size. Small glide-snow and loose-snow avalanches can trigger naturally. Avalanche danger above 2000m is MODERATE, below that altitude danger is low. Slabs, mostly small-sized, can be triggered even by minimum additiional loading both near to and distant from ridgelines and behind protruberances in the landscape on north, northwest and south facing slopes. If they fracture down to more deeply embedded layers in the snowpack the releases can grow to medium size. Isolated glide-snow avalanches reaching medium size are possible at any time of day or night.

Snowpack Structure

Often hardened snowdrift masses lie atop an expansively metamorphosed, loosely-packed snowpack surface with near-surface faceted crystals. Near surface crusts are weak layers of faceted, expansively metamorphosed crystals. Particularly in shady, shallow-snow zones there is snow which is rewarding to skiers, it is faceted, expansively metamorphosed powder which is settling increasingly with rising temperatures. In general, too little snow on the ground for this juncture of the season.

Weather Forecast

On Monday southerly foehn wind will ease of during the daytime, but in foehn lanes and and high altitudes can still reach 50-80 km/hr. High, generally thin clouds will hamper the sun somewhat, but most peaks will be in the clear, visibility good. At 2000m: 0 degrees; at 3000m: -5 degrees.

Tendency

Snowdrift problem receding further. Snowdrift problem stabilizing increasingly.
