Avalanche Activity

Increase in avalanche danger as a consequence of new snow and strong wind.

As a consequence of new snow and a sometimes storm force wind from southwesterly directions, avalanche prone wind slabs will form. They can be released even by a single winter sport participant. Mostly the avalanches are medium-sized. The avalanche prone locations are to be found in particular on shady slopes above approximately 2000 m, especially adjacent to ridgelines and in gullies and bowls. Individual gliding avalanches are possible, in particular medium-sized ones. Areas with glide cracks are to be avoided. This applies in particular on steep grassy slopes below approximately 2600 m.

Snowpack Structure

20 to 40 cm of snow, and even more in some localities, will fall above approximately 1400 m. The sometimes storm force wind will transport the new snow significantly. The fresh wind slabs will be deposited on soft layers in particular on steep shady slopes above the tree line. Towards its base, the snowpack consists of faceted crystals.

Tendency

In some regions 10 to 15 cm of snow, and even more in some localities, will fall on Saturday. Fresh wind slabs represent the main danger. A latent danger of gliding avalanches exists.
