Snowpack forfeiting its firmness on steep sunny slopes

Since the weekend there has been 10-20 cm of fresh snow registered widespread (with graupel). Stromy W/NW winds have transported the snow far-reachingly. Fresh snow and drifts cover surface hoar in shady, wind-protected zones, at higher altitudes it covers older snowdrift accumulations. Their proneness to triggering has diminished somewhat at high altitudes due to higher temperatures (there was brief rainfall up to 2200m). At low and intermediate altitudes the snowpack is intensely moistened due to solar radiation and higher temperatures, and is thus losing its firmness.

During the night, skies will be intermittently clear, no precipitation is expected. On Tuesday, sunshine will dominate. Winds in exposed terrain will reach peaks of 60 km/hr during the morning hours, otherwise winds will be moderate. Extremely mild. At 2000m: +2 degrees.

Little change expected on Wednesday.

Snowpack forfeiting its firmness on steep sunny slopes

Avalanche danger above the treeline is MODERATE. The main problem is freshly generated snowdrift accumulations which can trigger a small, and in isolated cases also a medium-sized slab avalanche even by minimum addiitional loading. Danger zones for slab avalanches occur near to and distant from ridgelines, behind protruberances in the landscape as well as in steep gullies and bowls, particularly on N/SE facing slopes. At low and intermediate altitudes, particularly on sunny slopes, naturally triggered small wet loose-snow avalanches can release, on very steep, unstructured terrain, e.g. grassy slopes, also naturally triggered glide-snow avalanches.
