Avalanche warning for region Voss Saturday 09.12.2017

Danger level 3 - Considerable avalanche danger

Published:
Wind and fresh snow may give instable conditions. Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Especially where the wind deposited slabs are thin or soft, a slab avalanche is easier to trigger there. Especially avoid convex terrain.

Avalanche problems

New snow (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Buried weak layer of new snow

Below you can see a description of the current snow cover information and current weather forecast in the mountains. If your observations deviate greatly from what is described here, the warning will not necessarily apply either. Always make your own judgments or stay away from avalanche terrain.

Advice

The bulletin is a planning tool and may differ from the actual situation. Always make your own evaluation. To be 100 % avalanche safe, avoid all avalanche terrain.

Avalanche risk assessment

Det ventes fortsatt lokalt mye nedbør, nå med kuling fra NV. Dette vil gi problem med ustabile nysnøflak i høyden, fortrinnsvis i Ø og S. For skiløpere betyr dette at det fortsatt vil være lett å løse ut skred opp mot str 3 i ferske leområder. I enkelte bratte leheng i høyden som har store henteområder for snø vil det være fare for naturlig utløste skred.
