Avalanche danger is not expected to change significantly in the next few days, risks will be subject to a daily danger cycle. The daily avalanche bulletins are hereby at an end for this season. A bulletin will be published whenever conditions merit.

Temperature at 2000m: -6 degrees. Light to moderate NE winds at high altitude. Snow cover / General info There are weak layers in the uppermost part of the snowpack in all aspects which can be triggered. Mostly these are the layers of fresh snow and drifts from last week. Yesterday a small slab avalanche was triggered remotely on a S/SE facing slope, preceded by whump-sounds and glide-cracks. Older drifts have often been covered, making them hard to recognize. The snowpack on sunny slopes became superficially moist yesterday. During the night, outgoing longwave radiation was inadequate, the snowpack was not able to regain its firmness. On shady slopes the upper layers are still powdery. On Saturday night there was a small amount of fresh snow registered. Avalanche danger assessment Avalanche danger is moderate above 2200 m, below that altitude danger is low. Main danger: weak near-surface layers are prone to triggering. Danger zones occur in all aspects. Avalanches can trigger especially by large additional loading, e.g. a group not maintaining distances; where snowpack layering is weak, even the weight of one single skier can trigger an avalanche. Settling noises and whumpf-sounds when the snowpack is tread upon are indicators of danger. Backcountry tours demand careful route selection. Due to daytime warming and diffuse radiation, danger of wet-snow avalanches rises during the day. Mostly small-to-isolated medium sized moist avalanches can trigger naturally in steep rocky terrain or by minimum additional loading. On steep grass-covered slopes and hillsides, small-to-medium glide-snow avalanches are possible below 2000 m particularly where snowfall has been heavy. Caution urged near glide cracks.
