Avalanche Activity

Favorable conditions, low avalanche danger

Avalanche danger is low. On very steep grass-covered slopes, mostly small glide-snow avalanches can trigger naturally. Isolated triggerings possible on extremely steep slopes. Apart from the risks of being buried in snow masses, the danger of being swept along and forced to take a fall need due consideration. On very steep grass-covered slopes, small, in isolated cases medium-sized glide-snow avalanches can trigger naturally.

Snowpack Structure

The snowpack was able to settle and consolidate somewhat due to higher temperatures and solar radiation. Particularly on shady slopes in the uppermost part of the snowpack there are weak layers evident which can easily be triggered. During the course of the day, superficially melt-freeze encrusted layers are becoming moist on steep sunny slopes, often wind crusts. On steep sunny slopes a melt-freeze crust is evident. Encrusted snowpack surfaces moisten during the day.

Weather Forecast

On Thursday, very sunny. In afternoon dense clouds will move in. From the northern rim of the Alps, low-lying high-fog like clouds (borderline at 1600m) will move into the Prealps and the valleys. The air will become noticeably colder. At 2000m: from +2 to -2 degrees. Moderate N/W winds at high altitudes.

Tendency

Avalanche danger levels are not expected to change significantly.
