Weak layers in the old snowpack necessitate caution. Wind slabs require caution.
Avalanches can be released in the weakly bonded old snow by a single winter sport participant. Caution is to be exercised in particular on steep west, north and east facing slopes above approximately 2000 m. Mostly avalanches are medium-sized. Isolated whumpfing sounds can indicate the danger. As a consequence of a moderate to strong wind, avalanche prone wind slabs formed in particular adjacent to ridgelines and in gullies and bowls. These can be released by a single winter sport participant, but they will be small in most cases. This applies in particular above approximately 2200 m. The number and size of avalanche prone locations will increase with altitude.
Some snow has fallen. As a consequence of a moderate to strong wind from northerly directions, hard wind slabs formed. The wind slabs are lying on surface hoar in some places above approximately 2200 m. Above approximately 2000 m: The snowpack will be prone to triggering. Distinct weak layers exist in the old snowpack. This applies in particular on west, north and east facing slopes.
Increase in avalanche danger as a consequence of the new snow. The weather report and anticipated change in the avalanche danger are uncertain.
