Stability: poor · Frequency: some
Weak layers in the old snowpack necessitate caution. Fresh wind slabs require caution.
Stability: poor · Frequency: some
As a consequence of a gusty wind from northerly directions, mostly small wind slabs formed. As a consequence of a strengthening wind from southerly directions, further wind slabs will form. The fresh wind slabs will be deposited on surface hoar in some places. The old snowpack is faceted and weak. Weak layers exist in the snowpack.
Weak layers in the old snowpack can still be released by individual winter sport participants. As a consequence of a strong wind from southerly directions, easily released wind slabs will form.
Weak layers in the old snowpack necessitate caution. Fresh wind slabs require caution.
Avalanches can be released in the weakly bonded old snow by a single winter sport participant. This applies in particular on west, north and east facing slopes above approximately 2200 m. Caution is to be exercised in particular in gullies and bowls, as well as at transitions from a shallow to a deep snowpack. Mostly avalanches are medium-sized. The fresh wind slabs can be released at elevated altitudes. This applies in particular adjacent to ridgelines. Mostly avalanches are small. The number and size of avalanche prone locations will increase with altitude. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger.
