Wind impact: small fresh drifts, still glide-snow avalanches
Avalanche danger is predominantly moderate. Main problem: snowdrift accumulations. Danger zones occur in steep wind-loaded terrain and ridgelines and increase in size and frequency with ascending altitude. A small-to-medium slab avalanche can be triggered by 1 person. At all altitudes in steep terrain and on smooth grass-covered slopes in all aspects, glide-snow avalanches are possible which can reach medium size. Caution in zones below glide cracks.
The large amounts of fresh fallen snow have been able to settle at lower altitudes and bond with the old snowpack. Winds have transported the fresh snow and led to new snowdrift masses. Wherever they blanket the fresh snow of soft layers or surface hoar, they are prone to triggering. Older snowdrifts are being increasingly blanketed over. At low and intermediate altitudes the base often is moist atop a warm ground, which favours gliding snow. There is currently little data available to the Avalanche Warning Service about the snowpack in various regions.
Nocturnal hours: Nighttime skies will be gray, light snowfall is expected, moderate in Bregenzer Wald. Wednesday: gray skies, fog, light snowfall (moderate in Bregenzer Wald). Only minor amounts expected. Cold. At 2000 m: -7 degrees. Brisk westerly winds.
The avalanche situation is not expected to change significantly.
