Snowpack Structure

The snowdrifts were able to settle and increasingly consolidate with the higher temperatures. The generally shallow snowpack is moist up to intermediate altitudes. Skiing tours and descents in outlying terrain below the timberline, often below 2000 m, are unrewarding due to the lack of snow. At low altitudes there is often no snow on the ground.

Avalanche Activity

Small drifts above the treeline require attentiveness

Mostly low danger prevails. On steep slopes which have not yet discharged, small glide-snow avalanches can trigger naturally. With ascending altitude the small trigger-sensitive snowdrift accumulations require attentiveness. On very steep sunny slopes small loose-snow avalanches are possible due to solar radiation.

Weather Synopsis

Thursday night: a front will reach Vorarlberg in the evening, precipitation will follow during the nocturnal hours. The snowfall level will descend from 1500 down to 1300 m. Friday: Some residual clouds with final rainfall will swiftly recede, drier air will follow with sunshine. In the afternoon clouds will again move in, minor precipitation is expected in the evening. At 2000 m: from -2 to +3 degrees. Winds will initially be brisk, intensifying in the evening, from the west.

Tendency

Avalanche danger will remain low.
