Avalanches can in some cases be released by a single winter sport participant, in particular on shady slopes above the tree line. The avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain. Mostly avalanches are rather small. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls. In the regions neighbouring those that are subject to danger level 3 (considerable) the avalanche danger is a little higher.
As a consequence of a strong to storm force wind from northeasterly directions, sometimes avalanche prone wind slabs will form in particular in gullies and bowls and behind abrupt changes in the terrain. The wind slabs will be deposited on soft layers in particular on steep west, north and east facing slopes. Faceted weak layers exist in the old snowpack especially on shady slopes. The snowpack will be subject to considerable local variations over a wide area. Only a little snow is lying.
Wind slabs require caution. The weather conditions will facilitate a slow stabilisation of the snow drift accumulations.
