Avalanche warning for region Voss Tuesday 22.12.2020

Danger level 2 - Moderate avalanche danger

Published:
Wind and fresh snow may give instable conditions in some slopes. 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. 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 or even kill you (size 2).

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

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

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.

Snow cover (in Norwegian)

Monday 21. December 2020

Snøoverflata ber preg av mildvêr høgt i fjellet og nedbør gjennom helga. Det er generelt lite snø i låglandet og snøen er jamt fuktig. Det ligg mest snø i vestvendt terreng og i konkave formasjonar. Ryggar og toppar er avblesne eller smelta fram.

Det er observert kantkorna snø over skarelag ved Mjølfjell og på vikafjellet over 800-900 moh. Kantkorn finst truleg der mildvêr laga skare tidleg i desember. Eit fjerutløyst skred ved Uppsete viser at dette laget er aktivt.

Mountain weather

Tuesday 22. December 2020

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

Stadvis mykje nedbør og sterk vind med endrande retning vil gje pålagring og nysnøflak i renner søkk og leheng i alle himmelretningar.

Ein lyt òg vere merksam på vedvarande svakt kantkornlag djupare i snødekket enkelte stadar.
