Main danger: snowdrift accumulations and weak layers in the old snow

At high altitudes mostly moderate avalanche danger prevails. Small fresh and older drifts are sometimes prone to triggering on shady slopes on wind-protected ridgeline slopes, and behind abrupt discontinuities in the terrain. The tend to increase with ascending altitude. Also, above 2400 m on steep shady slopes there are unfavourable layers in the old snowpack. As a result of daytime warming and solar radiation, small-to-medium wet-snow and glide-snow avalanches are possible, particularly on sunny slopes. The risks of being forced to take a fall should not be underestimated.

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. At high altitudes, esp. on steep shady slopes there are weak layers evident inside the snowpack. These danger zones are not visible to the naked eye. Below 1800 m there is only little snow on the ground; below 1200 m the ground is mostly bare. Reports from outlying terrain are sparse.

Nighttime hours: skies will be slightly cloudy, mostly clear until past midnight. In the latter part of the night, high-altitude cloudbanks will move in, some of them compact. Saturday: Intermittent sunshine, despite some cirrus clouds. Diffuse light conditions. The foehn wind will be palpable. At 2000 m: -1 to +4 degrees. Moderate to brisk SW winds.

On Sunday, strong foehn winds will bring layered clouds, but it will remain dry until evening. Avalanche danger levels are not expected to change significantly.
