Avalanche Activity

Considerable avalanche danger at high altitudes.

Considerable avalanche danger prevails. Avalanches can easily be triggered by one single winter sports enthusiast. Danger zones occur on steep slopes in all aspects, behind drops in the landscape and in wind-loaded gullies and bowls. Frequency and spread of avalanche prone locations increase with ascending altitude. Whumpf noises and fractures which appear when treading upon the snowpack, as well as freshly released avalanches are alarm signals. Activities in outlying terrain demand cautious assessment of the terrain and careful evaluation of the dangers. The inexperienced should not leave secured ski runs.

Snowpack Structure

By Friday midday additional 10-20cm of fresh snow, locally more, is anticipated. The large amounts of fresh fallen snow are continually being transported in varying directions, new snowdrift accumulations generated, but they are difficult to recognize since constantly getting blanketed with fresh snowfall. Fresh snow/drifts have settled slightly, but bonding to the unfavorable snowpack is usually weak.

Weather Forecast

Nocturnal snowfall will taper off during the course of the day on Friday, will be only sporadic in afternoon. Visibility limited due to fog and clouds. Temperature at 2000m: -6 degrees; at 3000m: -11 degrees. Brisk to strong-velocity north-to-northeasterly winds at high altitudes.

Tendency

Avalanche danger is diminishing only gradually. As a result of the forecast higher temperatures, wet-snow and glide-snow avalanches will be possible.
