Avalanche warning for region Helgeland Thursday 20.01.2022

Danger level 3 - Considerable avalanche danger

Published:
An increase in wind and snowfall will lead to a large amount of wind transported snow. Avoid all avalanche terrain. Naturally triggered avalanches likely.

Avalanche problems

Wind drifted snow (slab avalanches)

Avalanches may release spontaneously 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

Persistent weak layer (slab avalanches)

You can trigger avalanches on a few steep slopes. Avalanches can get large enough to bury a large truck or destroy several houses (size 4).

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 har de siste dagene kommet svært mye snø i fjellet, og snøværet fortsetter. Nysnø i kombinasjon med vind vil legge opp store flak med fokksnø i leområder som allerede har fått stor pålagring tidligere i uken. Skred kan løsne naturlig, og i noen områder kan skred bli svært store. Skredfaren er størst i de områdene der bygeværet treffer.

Varselet er basert på et enklere datagrunnlag enn regionale varsler og utgis kun i forbindelse med faregrad 4 og 5.
