Avalanche Activity

Wind slabs represent the main danger, in particular on shady slopes above approximately 2400 m.

The wind slabs of the last few days can be released in particular on steep shady slopes above approximately 2400 m. Avalanches can reach medium size. The prevalence of the avalanche prone locations will increase with altitude. Caution is to be exercised in particular adjacent to ridgelines and in gullies and bowls. Avalanches can in very isolated cases be triggered in the old snowpack and reach quite a large size. Avalanche prone locations are to be found in particular on steep shady slopes above approximately 2400 m. From origins in starting zones where no previous releases have taken place more gliding avalanches are possible, in particular medium-sized ones. This applies in particular on steep sunny slopes below approximately 2600 m, as well as on steep shady slopes below approximately 2200 m. Caution is to be exercised in areas with glide cracks.

Snowpack Structure

The fresh and somewhat older wind slabs are lying on soft layers on wind-protected shady slopes above approximately 2400 m. Faceted weak layers exist in the centre of the old snowpack in particular on west, north and east facing slopes. This applies above approximately 2400 m. As a consequence of rising temperatures and solar radiation a crust formed on the surface, in particular on steep sunny slopes in all altitude zones. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack, especially on sunny slopes, and on shady slopes at intermediate altitudes.

Tendency

As a consequence of mild temperatures and solar radiation the snow drift accumulations will stabilise. Gradual decrease in avalanche danger.
