Avalanche Activity

Caution: gliding snow and wet-snow avalanches during the daytime hours

Due to daytime warming and solar radiation, mostly small-sized wet loose-snow avalanches are possible. Also glide-snow avalanches continue to be naturally triggerable on steep, smooth slopes. On shady high-altitude slopes, older snowdrift accumulations are still prone to triggering. In general, only small slab avalanches can be triggered by winter sports enthusiasts.

Snowpack Structure

The old snowpack has been weakened by rainfall up to high altitudes. Due to adequate nighttime outgoing radiation the snowpack can consolidate superficially. During the daytime it softens up, particularly on sunny slopes, and the danger of wet-snow avalanches rises somewhat. Older snowdrift accumulations are still prone to triggering, particularly on shady slopes.

Weather Forecast

Very sunny and mild in the mountains, the air is extraordinarily dry. Temperature at 2000m: +5 degrees, at 3000m: +1 degree. High-altitude winds are southwesterly, blowing at light to moderate strength.

Tendency

The danger of dry-snow avalanches continues to decrease. Danger of wet-snow avalanches is subject to a daily danger cycle, rising slightly during the daytime.
