Tennen Mountains, Gosaukamm

Avalanche danger is moderate. Snowdrift accumulations above 2000m can often trigger a small-to-medium slab avalanche by one sole skier. Danger zones occur particularly in ridgelines zones and behind protruberances in the landscape. Superficially triggered releases above 2200m can fracture down to deeper layers of the snowpack. Danger zones occur in all aspects. Caution urged in transitions from shallow to deeper snow. Due to fresh snow, gliding snow activity will slightly increase. Caution urged below glide cracks.

Up to 20-30cm of fresh snow is expected, locally more. Winds in exposed terrain will be blowing above transport velocity, thus generating fresh snowdrift accumulations especially in ridgeline terrain. Weak layers for slab avalanches lie inside the fresh snow and fresh drifts. On shady slopes above 2000m the old snowpack can itself be a weak layer. Above 2200m there are several weak layers of faceted crystals inside the old snow, often prone to triggering. The entire snowpack can glide over steep rocky plates or grass-covered slopes.

Nocturnal skies will be mostly heavly cloud-covered, foehn winds will ease off significantly by midnight. In the latter part of the night, snowfall will set in from the south and west. Snowfall level: initially above 1500m, descending to valley level by morning. Initially, rainfall is possible in the southern regions up to 2000m. On Tuesday, snowfall from west and south, quickly spreading to all mountain regions. In the afternoon, drier from the west, possibly with brief bright intervals. All in all, in southern regions over 30cm. Visibility mostly heavily reduced. Winds mostly light to moderate, only at summit level in the Northern Alps will winds be brisk. At 2000m. -7 to -3 degrees; at 3000m: -11 degrees.

Little change expected before Wednesday
