Weather Synopsis

Wednesday night: only scattered clouds to begin with, later on becoming heavier, but it will remain dry. Thursday: very windy, relatively fine weather, dry in the mountains, some high-altitude cloudbanks, heavier in the afternoon hours, will pass through. In the evening and during the nocturnal hours, a front with precipitation is expected, snowfall down to 1500 m. Still relatively mild. At 2000 m: 0 to +2 degrees. Strong SW winds initially, slackening off in the afternoon.

Tendency

Avalanche danger will remain low.

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.

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.
