Avalanche Activity

Wind slabs represent the main danger. Gliding avalanches are possible.

As a consequence of new snow and a strong wind from westerly directions, sometimes avalanche prone wind slabs will form on north and east facing slopes. Avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain above the tree line. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. Such avalanche prone locations are barely recognisable because of the poor visibility. Avalanches can reach medium size. Gliding avalanches are possible, even large ones in isolated cases, in particular on steep east, south and west facing slopes below approximately 2600 m. Areas with glide cracks are to be avoided.

Snowpack Structure

Over a wide area 15 to 25 cm of snow will fall until midday. The strong wind will transport the fresh and old snow. The fresh wind slabs are in some cases prone to triggering. The somewhat older wind slabs have settled a little. Towards its base, the snowpack is largely stable.

Tendency

As a consequence of the occasionally storm force wind, fresh snow drift accumulations will form.
