Avalanches can be released by a single winter sport participant, in particular on very steep shady slopes at elevated altitudes. Individual avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain. In isolated cases avalanches are medium-sized. 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.
Over a wide area up to 15 cm of snow, and even more in some localities, will fall until Wednesday. The wind will be strong to storm force. The southwesterly wind will transport the new snow. The wind slabs will be deposited on a weakly bonded old snowpack in particular on steep northwest, north and east facing slopes. Shady slopes: The old snowpack consists of faceted crystals. The fresh wind slabs will be deposited on soft layers. Steep sunny slopes: The fresh wind slabs will be deposited on a crust. The snowpack will be subject to considerable local variations over a wide area.
Fresh wind slabs require caution.
