Fresh snow and drifts are trigger-sensitive esp on shady steep slopes, small-to-medium avalanches can be triggered by winter sports enthusiasts in steep terrain. Danger zones occur esp. on ridgeline shady steep slopes and in extremely steep terrain. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall require adequate caution. On steep grass-covered slopes with sufficient snow on the ground or atop smooth ground, increasingly frequent small-to-medium glide-snow avalanches are possible.
At high altitudes 20-30 cm of fresh snow was registered by Friday evening. During the night and on Saturday, another 5cm is expected regionally, accompanied by moderate-velocity winds which will deposited fresh snowdrifts atop soft layers on shady slopes, often with blanketed graupel, bonding only moderately good. The below average snowpack is well consolidated. On sunny slopes and at lower altitudes the fresh snow will fall on bare ground.
Only occasional rainfall and snowfall expected during the nocturnal hours. As of midnight, precipitation will intensify. On Sunday, clouds and fog will dominate. Up to 5-10 cm of fresh snow anticipated. At 2000m: -4 degrees. Mostly light winds at high altitudes.
Monday will be cool, increased sunshine expected as the day unfolds, with moderate-to-brisk E/NE winds. Avalanche danger levels not expected to change significantly.
