Favorable conditions. Caution urged towards small drifts.
Avalanche danger is low. Fresh drifts can trigger small slab avalanches even by minimum additional loading in some places. Danger zones occur in steep ridgeline terrain, mostly on NW/N/E facing slopes and behind protruberances in the landscape. Danger of being swept along and forced to take a fall outweigh that of being buried in snow masses. In very isolated cases, small slab avalanches can trigger in the old snow on steep shady high-altitude slopes, generally by large additional loading and where the snow is shallow.
The minor amount of fresh snow was transported. Small snowdrift accumulations lie deposited esp. on steep shady slopes atop soft layers and are often prone to triggering. The uppermost layers are often still powdery (with the exception of wind-impacted zones), frequently encrusted on south-facing slopes. Also wind-crusts are evident. All in all, the snowpack is predominantly well consolidated.
A dry night of foehn winds, due to which it will be quite sunny all day long on Saturday, with only loose high-altitude clouds. Temperatures will drop. At 2000m: from +7 to +2 degrees. Brisk to stormy S/SW winds at high altitudes.
No significant change anticipated in avalanche danger levels
