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 radiation. 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.
Precipitation with snowfall above 700m will taper off during the nighttime hours. On Monday, high-fog type cloud cover above 2000m will limit visibility. In afternoon it will disperse, sunshine will emerge. At 2000m: -7 degrees. Moderate to often brisk NE winds at high altitudes.
Starting on Tuesday, sunshine will dominate and temperatures will rise. Increasingly frequent slides and wet-snow avalanches can be expected during the course of the day.
