With the end of the intense snowfall, the natural activity of slab avalanches will gradually increase. For this reason the avalanche danger will decrease during the day to level 3 (considerable).
As a consequence of new snow and a moderate to strong wind, wind slabs formed in particular adjacent to ridgelines and in gullies and bowls as well as at intermediate and high altitudes. Over a wide area they will increase in size substantially during the course of the night. Sometimes the avalanches are large and very easily released. As a consequence of the snowfall snow slides and avalanches are to be expected as the day progresses, in particular medium-sized ones. The avalanche prone locations are to be found on steep sunny slopes and on wind-protected shady slopes. The peak of avalanche activity will be reached during the second half of the night probably.
Evening and night: Over a wide area 50 to 60 cm of snow will fall above approximately 2000 m. The sometimes storm force wind will transport the new snow significantly. During the day: The weather will be partly cloudy. In some cases the wind slabs have bonded poorly with each other and the old snowpack.
Monday: Decrease in danger of dry avalanches as a consequence of the ceasing of precipitation.
