Distinct weak layers in the old snowpack are treacherous.
Distinct weak layers in the old snowpack can still be released by individual winter sport participants in particular on west, north and east facing slopes. This applies in particular below approximately 2500 m, in isolated cases also on steep sunny slopes at elevated altitudes. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Avalanches can reach dangerously large size. Remotely triggered avalanches are possible. The wind slabs of the last few days are in some cases still prone to triggering in high Alpine regions, especially adjacent to ridgelines. The danger of gliding avalanches and moist snow slides will increase a little during the day, in particular on steep sunny slopes. The current avalanche situation calls for defensive route selection.
Faceted weak layers exist in the centre of the snowpack, especially on west, north and east facing slopes below approximately 2500 m, in isolated cases also on sunny slopes at elevated altitudes. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger.
A sometimes treacherous avalanche situation will persist.
