Avalanche Activity
NW-wind generated snowdrift accumulations
Danger of avalanches is MODERATE. Avalanche prone locations focus on gullies in all aspects and wind-loaded steep slopes, fresh snowdrifts found increasingly frequent in E/S aspects. The shallow-snow transition zones are especially treacherous. Triggering a small-to-medium sized slab avalanche is possible there by large additional loading, where snow is shallow in transition zones even by minimum additional loading from the drifted zones.
Snowpack Structure
The strong winds which frequently changed directions have left their marks on the snowpack, generated snowdrift accumulations in all aspects. Most recently, NW winds and rising temperatures have formed compact snowdrift masses. Snow quality is far better in wind-protected zones, here there is powder. Bonding of individual snowdrifts deteriorates with ascending altitude.
Weather Synopsis
On Tuesday, frequent sunshine, some fogbanks at low altitudes. It will remain free of precipitation. At high altitudes, brisk NW winds will be blowing. At 2000 m: +1 degree. On Wednesday, visibility will initially be limited by clouds and fog. In the afternoon, the visibility will improve and the sun will come out. Winds in exposed terrain, NW winds will be blowing at moderate strength. At 2000 m: -2 degrees.
Tendency
The likelihood of avalanches triggering will gradually diminish.
