Wind impact above the timberline

Avalanche danger above 2400 m is considerable, below that altitude danger is moderate. Fresh drifts can be triggered even by 1 person in steep terrain, and reach medium size. In high alpine zones it is possible that slab fracture down to more deeply embedded layers of the snowpack and grow to large size. Avalanches can trigger naturally in extremely steep rocky terrain (small-to-medium). Danger of naturally triggered glide-snow avalanches persists below 2300 m. Where snow is deep enough, they can reach medium size. Avoid zones below glide cracks.

Latest standing: temperatures dropping, 30-45 cm of fresh snow widespread, winds have formed snowdrifts, sometimes prone to triggering. Weak layers are evident inside the fresh fallen snow. The base is largely stable although highly irregular. Large-area weak layers are unlikely. On shady high-alpine slopes there are crusts inside the old snowpack at which faceted layers are attached, these will trigger with large additional loading. The old snowpack base is moist. Due to the weight of the fresh snowfall, the tendency of the entire snowpack to glide downhill is thus reinforced.

Following a night of clear and windless skies, visibility on Tuesday will be mostly good, frequent sunshine is expected, only stray fogbanks. Moderate SE wind (40 km/hr). At 2000 m: -8 degrees. Sunny weather will continue on Wednesday, the SE winds will slacken off, temperatures rise slightly.

Avalanche danger levels are not expected to change significantly. Consequently AVOID the fresh drifts.
