Avalanche Activity

Wind slabs and weakly bonded old snow require caution.

The fresh and older wind slabs must be evaluated with care and prudence in particular on northwest to north to northeast facing aspects above approximately 2000 m. Avalanches can in isolated cases be released in the old snowpack and reach medium size on very steep northwest, north and northeast facing slopes. As a consequence of warming during the day and solar radiation small and, in isolated cases, medium-sized moist loose snow avalanches are possible.

Snowpack Structure

In some localities up to 10 cm of snow, and even more in some localities, will fall. As a consequence of a sometimes strong wind from variable directions, sometimes avalanche prone wind slabs formed in the last few days. The fresh and somewhat older wind slabs are lying on the unfavourable surface of an old snowpack. Distinct weak layers exist in the bottom section of the snowpack in particular on steep shady slopes. This applies especially above approximately 2000 m. Steep sunny slopes: Sunshine and high temperatures will give rise to moistening of the snowpack.

Tendency

Fresh wind slabs are in some cases still prone to triggering in particular on steep shady slopes. The avalanche danger will decrease gradually.
