Tennen Mountains, Gosaukamm

Springtime situation

Solar radiation makes the snowpack wet, it loses its firmness. In transitions from old snowpack to fresh snow are faceted layers above 2400 m near crusts which are potential weak layers for slab avalanches. On steep rocky slopes which have again been snow on and grassy slopes, the snowpack is wet down to the ground and can glide away. Up to 2800 m on south facing slopes a melt-freeze crust will form on Saturday night which is capable of bearing loads, then turning to firn in daytime. On steep north-facing slopes, breakable crusts can be expected.

On Monday night skies will be mostly clear but for a few clouds and Sahara dust reducing outgoing radiation somewhat. On Tuesday lots of sunshine, high cirrus clouds, southerly winds intensifying (to 80 km/hr) also away from Main Alpine Ridge. At 2000 m: from 4 rising to 8 degrees. On Tuesday night, clear skies, brisk southerly winds, but less than during daytime.

Springtime situation

Avalanche danger rises to MODERATE during the course of the day. Due to solar radiation, increasing wet-snow activity is expected during the daytime. Beginning on extremely steep slopes (>40°) in southern and eastern aspects, it will then spread to all aspects, releases small-to-medium. also triggerable by 1 person. Below 2600 m where the snow is sufficient, naturally triggered glide-snow avalanches can be expected on steep slopes, particularly where the recent fresh snow fell on bare ground. Avoid zones below glide cracks.. Above 2600 m, near-surface weak layers can trigger a slab in isolated cases, esp. on very steep slopes (>40°) by large additional loading (e.g. cornices collapsing, group w/o distances).

Classic springtime will continue
