Stability: poor · Frequency: some
Weak layers in the old snowpack can be released by individual winter sport participants in particular on steep shady slopes.
Avalanches can be released by a single winter sport participant. They can penetrate down to the ground, in particular in starting zones that have retained the snow thus far. Caution is to be exercised on steep west, north and east facing slopes above approximately 1800 m. In many cases avalanches are medium-sized. In addition the fresh wind slabs adjacent to ridgelines and in gullies and bowls are prone to triggering. The number and size of avalanche prone locations will increase with altitude. Whumpfing sounds can indicate the danger.
Over a wide area 10 cm of snow has fallen. As a consequence of a gusty wind, further wind slabs will form in the course of the day. The wind slabs are lying on the unfavourable surface of an old snowpack at elevated altitudes. Above approximately 1800 m: The snowpack will be in some cases prone to triggering. Distinct weak layers exist in the old snowpack. This applies in particular on west, north and east facing slopes.
Avalanches can as before be released by a single winter sport participant.
