Avalanche Activity

New snow and wind slabs above approximately 1800 m. The new snow can be released naturally in all aspects above approximately 2200 m. In addition the wind slabs in gullies and bowls, and behind abrupt changes in the terrain are capable of being triggered. Weak layers exist in the old snowpack in particular on steep shady slopes.

As a consequence of new snow and a strong southwesterly wind, sometimes easily released wind slabs formed in particular adjacent to ridgelines and in gullies and bowls. On steep shady slopes and in gullies and bowls, and behind abrupt changes in the terrain slab avalanches are possible, even large ones.

Snowpack Structure

The snowpack will become unstable over a wide area. As a consequence of heavy snowfall and the strong southwesterly wind, a very precarious avalanche situation developed on Tuesday.

Tendency

New hazard assessment tomorrow due to the discrepancy between models regarding the expected amounts of fresh snow.
