Avalanche warning for region Trollheimen Friday 31.12.2021

Danger level 3 - Considerable avalanche danger

Published:
Avoid 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.

Avalanche problems

Wind drifted 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).

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

Vind og meir nysnø i fjellet vil føre til stadig meir pålagring av fersk fokksnø i leheng. Ver merksam på at vindretninga endrar seg i løpet av dagen og fleire himmelretningar vil bli utsatt.
I låglandet der snødekket er fuktig eller vått vil det truleg stabilisere seg raskt når nedbøren minkar og temperaturen synker.
