Avalanche Activity

Fresh drifts prone to triggering in places

Through fresh snow and wind, snowdrift accumulations have been generated which are prone to triggering. Danger zones tend to increase in frequency with ascending altitude and occur particularly in steep shady terrain, but also behind protruberances in the landscape, in wind-loaded gullies and bowls. Avalanches can in places be triggered by one sole skier and reach medium size. Snowdrift accumulations need to be assess with great caution, particularly in steep terrain. The danger of small, in isolated cases medium-sized glide-snow avalanches is still difficult to assess. Caution urged below glide cracks.

Snowpack Structure

Fresh snow registered (10-20cm, locally more), deposited on a largely well consolidated old snowpack, then transported by initially SW winds, then northerly winds. The initially shallow snowpack accumulations are often prone to triggering. Esp. on shady slopes and in wind-protected zones at high altitudes, snowdrift will be deposited atop a loose snowpack surface, often atop breakable crusts, sometimes on crusts which can carry loads and on steep sunny slopes atop a melt-freeze crust.

Weather Forecast

Snowfall for a spell tomorrow, but only a few cm will fall. In afternoon, visibility will improve, some sunshine is possible (though pale). At 2000m: -13 degrees. Light northerly winds, moderate strength in high alpine regions.

Tendency

Avalanche danger levels will slowly recede.
