Avalanche Activity

Weakly bonded old snow especially in shady places that are protected from the wind. Small and medium sized avalanches are possible.

In many cases new snow is lying on old snow containing large grains. Precarious weak layers exist in the snowpack on wind-protected shady slopes. In isolated cases the avalanches are medium-sized and can be released in some cases even by a single winter sport participant.

Snowpack Structure

Some fresh snow and the mostly small wind slabs are poorly bonded with the old snowpack in particular on steep north, northeast and northwest facing slopes above approximately 2300 m. Faceted weak layers exist in the bottom section of the old snowpack in shady places that are protected from the wind. At low and intermediate altitudes from a snow sport perspective, insufficient snow is lying.

Tendency

The fresh snow and the mostly small wind slabs are lying on the unfavourable surface of an old snowpack on north to northeast to northwest facing aspects.
