Carnic Alps Lesachtal

Fresh wind slabs require caution.

Fresh wind slabs require caution.

As a consequence of the strong to storm force northwesterly wind, fresh snow drift accumulations will form. The wind slabs are in some cases prone to triggering in particular on steep shady slopes above approximately 2200 m. This applies especially adjacent to ridgelines and in gullies and bowls. The number and size of avalanche prone locations will increase with altitude. In isolated cases avalanches can be triggered in the weakly bonded old snow. Such avalanche prone locations are to be found in particular on extremely steep shady slopes above approximately 2600 m. Mostly avalanches are small. Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls.

The fresh and older wind slabs are lying on soft layers in particular on shady slopes at elevated altitudes. Shady slopes above approximately 2600 m: Faceted weak layers exist in the bottom section of the snowpack. The snowpack will be generally subject to considerable local variations. A little snow is lying in all altitude zones. Steep south facing slopes: Hardly any snow is lying.

As a consequence of a sometimes strong wind from northerly directions, further wind slabs will form. These represent the main danger.
