Weakly bonded old snow requires caution.
Winter sport participants can release avalanches in isolated cases. Avalanches can be released in near-ground layers and reach medium size. The avalanche prone locations are to be found in particular on very steep west, north and east facing slopes above approximately 2000 m. Such avalanche prone locations are rare but are barely recognisable. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. In addition the small wind slabs adjacent to ridgelines and in gullies and bowls are capable of being triggered in isolated cases, in particular on very steep shady slopes.
Above approximately 2000 m: Avalanche prone weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. The mostly small wind slabs of Sunday are lying on soft layers in particular on shady slopes. As a consequence of a freshening westerly wind, further wind slabs will form in the course of the day in some regions. Below approximately 2000 m and steep sunny slopes: The old snowpack will be moist.
Weakly bonded old snow requires caution. Some snow will fall.
