Caution: fresh and blanketed drifts, glide-snow avalanches
Avalanche danger is considerable at higher altitudes. Main problem: fresh or covered snowdrift accumulations. Danger zones occur in steep wind-loaded terrain and ridgelines and increase in size and frequency with ascending altitude. A medium slab avalanche can be triggered by 1 person. Activities in outlying terrain require experience in assessing the terrain and avalanche dangers. 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 with little wind have been able to settle at lower altitudes and bond with the old snowpack. In places there are soft layers or older snowdrift accumulations which have been blanketed over, and recognizing the danger zones is difficult. Particularly on steep shady slopes above 2200 m, the old snowpack from late autumn still has unfavourable intermediate layers which are triggerable as slab avalanches. 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.
Avalanche danger levels will recede
