Caution: freshly generated snowdrift accumulations at high altitudes
Fresh snow and drifts are triggerable esp. on steep shady slopes. One sole skier can trigger a small-to-medium loose-snow or slab avalanche. 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, isolated small-to-medium glide-snow avalanches are possible. In rocky terrain, slides and small loose-snow avalanches are possible.
The fresh snow which has fallen since Thursday has in the interim settled and increasingly consolidated at intermediate altitudes due to solar radiaiton. On steep slopes it is still loose and soft. Fresh snow and small drifts lie deposited on shady slopes atop expansively metamorphosed, soft layers, often blanketing 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. Thus, more snowdrifts will be generated at high altitudes.
