Circumvent fresh snowdrifts
Due to NW winds, trigger-sensitive snowdrifts are accumulating at high altitudes. Also the near-surface weak layers are prone to triggering in steep shady little-tracked terrain. One sole skier can trigger and small-to-medium sized slab avalanche in these zones. Wind-loaded steep terrain should be evaluated with caution. Small, in isolated cases medium-sized glide-snow avalanches are still possible. Due to daytime warming and solar radiatio, increasingly frequent loose-snow avalanches can trigger naturally on sunny slopes in steep rocky terrain.
Since yesterday there has been 20cm of fresh snow registered. Winds from northerly directions have generated fresh snowdrift accumulations which were deposited atop soft layers and are prone to triggering. The snowpack is thoroughly wet up to high altitudes. Gliding movements of the snow masse over smooth ground are still possible.
An intermediate high. A few snowflakes can fall from the residual clouds, mostly it will be dry. Clouds and fog will disperse and provide space for sunshine. After a few pleasant hours, cloudbanks will move in with the next front, further snowfall is anticipated. At 2000m: -2 degrees. Moderate to brisk NW winds at high altitudes.
On Monday, frequent and persistent snowfall, large amounts of fresh fallen snow are expected. Avalanche danger levels will continue to rise due to fresh snowdrifts at high altitudes
