Snowpack & Weather
Snowpack
Precipitation set in on Saturday, first in the south and later also in the north. Before this snowfall, conditions had been generally sunny and dry in the mountains for almost two weeks.
In gullies and bowls on shady slopes above around 2000 m and in high Alpine regions, the fresh and drifted snow fell on a patchy continuous snowpack, otherwise on bare ground. On shady slopes above approximately 2400 m and generally in high Alpine regions, the fresh snow has fallen on pronounced weak layers, where avalanches can easily be triggered.
Outlook
On Wednesday, conditions will be sunny in the mountains and cloudy but dry on the southern flank of the Alps. There will moderate, sometimes strong, southwesterly winds in high Alpine regions. Widespread precipitation will set in during overnight to Thursday. The snowfall level will drop to low altitudes. By Thursday afternoon, 10 to 20 cm of snow will fall on the northern flank of the Alps, elsewhere a few centimetres.
The avalanche hazard will decrease slightly on Wednesday. It may increase slightly on Thursday, especially on the northern flank of the Alps. There will be little change in other regions. Caution should be exercised around fresh snowdrift accumulations. In addition, isolated avalanches may be triggered in the old snowpack, especially on northern slopes above 2400 m and in high Alpine regions.
