Fresh snow/snowdrifts increasingly trigger-prone with ascending altitude

Fresh snow/snowdrifts increasingly trigger-prone with ascending altitude

Avalanche danger above 1800 m is considerable, below that altitude danger is moderate. Fresh drifts can trigger a medium slab by 1 person. Danger zones occur esp. in steep ridgeline terrain, behind discontinuities and in gullies and bowls. Frequency and size of danger zones increase with ascending altitude. Activities in outlying terrain demand experience in assessing avalanche dangers on-site. Isolated glide-snow avalanches are possible. Avoid zones below glide-cracks. In case of extended bright intervals, small loose-snow avalanches are possible.

An additional 20-40 cm of fresh snow plus intermittently strong winds will generate fresh snowdrift accumulations. With ascending altitude, the fresh snow and drifts lie deposited atop soft layers and are prone to triggering; also the drifts and uppermost layers of the snowpack lie atop weak layers (wind and graupel). The snowpack is moist-to-wet down to the ground up to high altitudes. Gliding snow activity has receded due to lower temperatures, but small glide-snow avalanches are still being observed on ground which was bare of snow prior to this bout of precipitation.

Nocturnal hours: Gray skies, intermittent snowfall, even down to low lying areas. Sunday daytime: Late winter scenario: snowfall and graupel showers, fog and snowfall reduce the visibility, only brief intervals of sunshine. At 2000 m: -6 degrees. Light to moderate northerly winds.

In the southern regions, light snowfall on Monday. Further north, mostly dry. It will remain cold in the mountains. Avalanche danger levels are not expected to change significantly.
