Weakly bonded old snow represents the main danger.
Stability: poor · Frequency: some
As a consequence of a strong wind from northwesterly directions, avalanche prone wind slabs formed 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.
Increase in avalanche danger as a consequence of the new snow. The weather report and anticipated change in the avalanche danger are uncertain.
Weakly bonded old snow represents the main danger.
Weak layers in the lower part of the snowpack can still be released in some places by individual winter sport participants. Caution is to be exercised in particular on steep west, north and east facing slopes above the tree line. The avalanche prone locations are difficult to recognise. Isolated whumpfing sounds can indicate the danger. Mostly avalanches are medium-sized. In addition the small wind slabs of the last few days adjacent to ridgelines are prone to triggering in isolated cases still, especially on very steep shady slopes at elevated altitudes. They are clearly recognisable to the trained eye.
