Weak layers in the old snowpack necessitate caution.
Avalanches can be released in the weakly bonded old snow by a single winter sport participant. This applies in particular on west, north and east facing slopes above approximately 1800 m. In addition the fresh wind slabs in particular in gullies and bowls, and behind abrupt changes in the terrain are prone to triggering. In isolated cases avalanches are medium-sized. The number and size of avalanche prone locations will increase with altitude. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger.
5 to 10 cm of snow will fall. The snowpack is unfavourably layered. Distinct weak layers exist in the old snowpack. This applies in particular on west, north and east facing slopes above approximately 1800 m. As a consequence of a gusty southerly wind, soft wind slabs will form. These will be deposited on surface hoar in particular on wind-protected shady slopes.
The weather report and anticipated change in the avalanche danger are uncertain.
