Distinct weak layers in the old snowpack necessitate caution.
Distinct weak layers in the old snowpack can be released even by individual winter sport participants. Mostly avalanches are medium-sized. Caution is to be exercised in particular on steep west, north and east facing slopes above approximately 1800 m. The avalanche prone locations are difficult to recognise. Isolated whumpfing sounds can indicate the danger. In addition the mostly small wind slabs in particular adjacent to ridgelines and in gullies and bowls are prone to triggering. This applies in particular above approximately 2000 m. They are clearly recognisable to the trained eye.
Some snow will fall. As a consequence of a strong wind from northwesterly directions, avalanche prone wind slabs will form especially in gullies and bowls. Somewhat older wind slabs are lying on surface hoar in some places. Above approximately 1800 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.
Weak layers in the old snowpack represent the main danger.
