Avalanche Activity

Afternoon: Down to low altitudes snow will fall. New snow and wind slabs require caution.

As a consequence of the moderate to strong westerly wind, fresh snow drift accumulations formed. These can in some places be released by a single winter sport participant and reach large size in isolated cases. This applies in particular on steep slopes also in areas close to the tree line, as well as in gullies and bowls, and behind abrupt changes in the terrain above the tree line. Avalanche prone weak layers exist in the snowpack in particular on steep shady slopes. The current avalanche situation calls for experience in the assessment of avalanche danger and careful route selection. Afternoon: Significant increase in danger of dry avalanches as a consequence of the snowfall.

Snowpack Structure

Over a wide area new snow is lying on surface hoar. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and natural avalanches serve as an alarm indicating the danger. Intermediate and high altitudes: Individual weak layers exist in the bottom section of the snowpack in particular on very steep shady slopes. The current avalanche situation calls for experience in the assessment of avalanche danger and caution.

Tendency

As a consequence of new snow and wind the prevalence and size of the avalanche prone locations will increase during the night.
