Avalanche Activity
Avoid freshly generated snowdrifts!
Avalanche risk above the timberline is moderate, below that altitude it is low. Main problem: fresh snowdrifts. Small slab avalanches can be triggered in some places even by minimum additional loading. Danger zones occur in steep ridgeline terrain in N/NW/SE aspects and in wind-loaded gullies and bowls. Avalanches can in isolated cases sweep away deeper weak layers of the snowpack, but still remain small-sized.
Snowpack Structure
Particularly on steep shady slopes, unfavorable intermediate layers inside the old snowpack have often persisted. During recent nights, surface hoar has often been generated. The melt-freeze crust which formed overnight softens up on sunny slopes during daytime hours. At lower altitudes there is little snow on the ground. South-facing slopes are increasingly becoming bare of snow.
Weather Forecast
Foehn wind impact: following a heavily clouded night of dry skies, the daytime hours will be quite sunny. Limited visibility on main ridge of Silvretta and Rätikon. Temperature at 2000m: +1 degree; at 3000m: -5 degrees. Strong to storm-strength southwesterly winds, with wind-chill, require caution.
Tendency
No significant change anticipated
