Wednesday will bring some bright intervals, the snow showers will taper off. It will remain cold. The avalanche situation will remain tense.

By Wednesday morning, an additional 10-30 cm of fresh snow is possible, locally even more. Temperature at 2000 m: -9 degrees. Moderate to strong NW winds. Snow cover / General info Since Monday there has been 30-40 cm of fresh snow registered which fell with interruptions, 40-60 cm from Arlberg over Hochtannberg into Kleinwalsertal, more from place to place. In Langen am Arlberg 71 cm of fresh snow was registered, 56 cm in Mittelberg, Kleinwalsertal. The 3-day overall amounts lie at 60-110 cm. Intermittently the fresh snow was intensively transported by W/NW winds. Exposed zones are often windblown., gullies and bowls filled with drifts. On shady slopes, snowdrift accumulations were often deposited atop soft old snow layers, on sunny slopes mostly atop hard, encrusted layers. In addition, graupel was often blanketed over. Bonding to the old snowpack surface and within the layers of fresh snow and drifts is frequently weak. The fundament is generally well consolidated, mostly stable. Avalanche danger assessment High avalanche danger threatens widespread above the timberline. Major peril: fresh snow and snowdrifts. Avalanche prone locations are found with ascending altitude primarily in steep ridgeline terrain, behind protruberances, in freshly wind-loaded gullies and bowls. Both fresh snow and freshly generated drifts are prone to triggering there. Size and frequency of danger zones increase with ascending altitude and as the day progresses. Medium-to-large slab avalanches can be triggered by the weight of one single skier. Activities in backcountry require much experience in assessing avalanche risks on-site. As snowfall and wind transport continue during the day, increasingly frequent medium-to-large naturally triggered loose-snow avalanches and, in heavily wind-loaded zones, also slab avalanches are possible. Exposed sectors can be endangered. Safety personnel take note!
