Avalanche Activity

Snowdrifts often still prone to triggering at high altitudes

Fresh snow and drifts of the last few days make triggering small-to-medium sized avalanches by one sole skier possible. Danger zones tend to increase in frequency with ascending altitude, particularly on steep shady slopes, but also behind protruberances in the landscape. Activities in backcountry demand much experience in assessing dangers and defensive conduct. At lower altitudes, danger is moderate. In addition, on very steep grassy slops, small-to-medium glide-snow avalanches can trigger naturally.

Snowpack Structure

Due to often strong southerly winds, the latest bout of fresh snowfall was transported to highest-altitude ridgeline terrain and exposed terrain, on north-facing slopes to loose snowpack surface. The drifts particularly there are often poorly bonded with the old snowpack and are prone to triggering. Avalanches in these zones are especially possible inside the fresh snow and drifts and in transitions to the old snow. Often the drifts of recent days have been blanketed. On sunny slopes the most recent snowfall is already bonded. The snowpack beneath it is generally well consolidated. At lower altitudes the fresh snow often fell on bare ground.

Weather Forecast

Dense clouds, peaks often in fog, poor visibility. In the morning, light snowfall is possible, esp. between Allgau Alps, Bregenzerwald mountains and the Prealps. In afternoon bright intervals possible, but limited visibility. At 2000m: -6 degrees to -4 degrees. Light to moderate S/SW winds.

Tendency

Avalanche danger levels will decrease further
