Problèmes avalancheux

  • New snow

    • Toutes altitudes

  • Persistent weak layers

    • Toutes altitudes

Snowpack Structure

New snow to low altitudes. Over a wide area 30 cm of snow, and even more in some localities, fell on Thursday. The new snow of Thursday is lying on soft layers. The soft wind slabs are poorly bonded with the old snowpack in all aspects. Precarious weak layers exist in the snowpack in particular on shady slopes.

Avalanche Activity

Backcountry touring and snowshoe hiking call for meticulous route selection.

The new snow can be released by a single winter sport participant. The conditions brought about a weakening in deep layers of the snowpack in particular on steep north, northeast and east facing slopes. Avalanches can also be released in near-ground layers and reach large size in particular on steep shady slopes. The avalanche prone locations are quite prevalent and are difficult to recognise.
