  • Persistent weak layers

    • Below 2,500 m

Avalanche Activity

Natural avalanches are still possible.

In particular adjacent to ridgelines and in gullies and bowls as well as above approximately 2200 m wind slabs will form. The fresh wind slabs can be released naturally especially on northwest to east to southwest facing aspects. Medium-sized natural avalanches are possible in particular in starting zones where no previous releases have taken place. Additionally in some places dry avalanches can also be released in near-ground layers. The fresh wind slabs can be released by a single winter sport participant in some cases. Weak layers exist in the snowpack on steep north, northeast and northwest facing slopes. At transitions from a shallow to a deep snowpack, when entering gullies and bowls for example and on steep shady slopes the avalanche danger is higher.

Snowpack Structure

In some localities 10 to 20 cm of snow has fallen. The sometimes strong wind will transport the snow. Weak layers exist in the snowpack especially on shady slopes. Snow depths vary greatly above approximately 1900 m, depending on the infuence of the wind.

Tendency

The natural avalanche activity will gradually decrease.
