Problèmes avalancheux

  • Wind slab

Tendency

With foehn storms, prone to triggering snowdrift accumulations continue to grow, especially at high altitudes.

Avalanche Activity

Some avalanche prone locations in fresh wind slab.

The avalanche risk is moderate above the tree line and low below. The main problem is fresh wind slab. Small slab avalanches can be triggered in some places by even a small additional load. Avalanche prone locations are adjacent to ridgelines and distant from ridgelines in steep terrain with aspects from north-west to north to south-east as well as in gullies and bowls. Avalanches can occasionally tear through weak layers of persistent weak layer and then become medium sized. In addition to the risk of burial, the risk of falling and injury must be taken into account.

Snowpack Structure

With stormy south-westerly winds, small, fresh snowdrift accumulations develop at altitude. They come to rest prone to triggering on surface hoar and soft layers. The old snowpack consists of large, angular and rounded crystals and is partly interspersed with melt-freeze crusts. There is little or no snow up to high altitudes on the sunny slopes.
