The danger of dry and moist avalanches will increase during the day.
As a consequence of new snow and a sometimes strong southerly wind, further wind slabs will form from early morning in particular adjacent to ridgelines and in pass areas. The fresh and somewhat older wind slabs can be released easily. or in isolated cases naturally, in all aspects. In many cases avalanches are medium-sized. Dry avalanches can also be triggered in the old snowpack and reach dangerously large size. During the day: As the penetration by moisture increases moist snow slides and avalanches are possible, even medium-sized ones. Gliding avalanches can be released at any time of day or night. Backcountry touring and other off-piste activities call for extensive experience in the assessment of avalanche danger and great restraint.
30 to 50 cm of snow, and even more in some localities, fell in the last three days above approximately 1500 m. Especially in the south and in the southwest 5 to 10 cm of snow will fall above approximately 2000 m. The southerly wind will transport the new snow and, in some cases, old snow as well. Over a wide area new snow and wind slabs are lying on a weakly bonded old snowpack. Large-grained weak layers exist in the bottom section of the old snowpack in particular on west, north and east facing slopes. At intermediate altitudes there are 130 to 170 cm of snow, and even more in some localities.
Tuesday: Significant decrease in danger of moist avalanches as the temperature drops.
