Tennen Mountains, Gosaukamm

Isolated weak layers at high altitudes

Springtime conditions with firn snow, depending on hour of day and aspect. The snowpack is compact and thoroughly wet up to 2000 m, on sunny slopes up to 2600 m, wet down to the ground. On shady slopes above 2200 m, older snowdrift patches lie atop loose snowpack layers with near-surface faceted crystals, only seldom triggerable. Beneath 1300 m there is hardly any snow on the ground.

On Tuesday night, clear skies. On Wednesday morning still sunshine and good visibility. As of midday clouds moving in from the northwest, summits should stay in the cleare. Strong westerly winds up to 60 km/hr. At 2000 m: 0 degrees.

The gliding snow problem will persist. Avalanche danger levels are not expected to change significantly.

Isolated weak layers at high altitudes

Avalanche danger is generally low. Main problem: glide-snow avalanches. In danger zones which have not yet discharged on steep grassy slopes in all aspects, glide-snow avalanches are possible at any time of day or night, medium releases possible, on sunny slopes up to 2600 m. Avoid zones below glide cracks. On high altitude shady slopes (above 2200 m) isolated weak layers in the snowpack can be problematic, triggerable mostly near ridges, behind discontinuities and in transitions from shallow to deeper snow on steep shady slopes, sometimes reaching large size. Slab avalanches from snowdrifts remain small, occasionally medium-sized. Caution of falling.
