Heed small drifts at high altitudes
Heed small drifts at high altitudes
Low avalanche danger. Fresh drifts are often prone to triggering in shady, wind-protected ridgeline terrain. In zones where avalanche danger is low, isolated small releases are possible in extremely steep terrain. In steep terrain where there is a melt-freeze crust on the surface, the danger of being forced to take a fall should not be underestimated.
At high altitudes, the recent and also some older snowdrift accumulations are often still prone to triggering They lie deposited atop loose and soft layers or melt-freeze encrusted surfaces. Bonding is only moderate. The snowpack has settled further in the last few days and is well consolidated by and large. Below 1800 m there is only little snow on the ground; below 1200 m the ground is mostly bare.
During the night: rainfall will slacken off, the latter part of the night will be dry. In Rhine Valley and at Lake Constance, high fog-like residual cloud will persist, elsewhere the clouds will disperse. Friday: apart from residual cloud at the edge of the Rhine Valley and the Alpine Prealps, sunshine right from the start. Cirrus clouds passing through will not be a disturbance. Winds will ease. Temperature at 2000 m: 0-3 degrees. Moderate to brisk westerly winds.
Saturday will be intermittently sunny, and quite mild. Foehn wind will arise in the mountains. Avalanche danger levels are not expected to change significantly.
