Avalanche warning for region Trollheimen Thursday 27.01.2022

Danger level 3 - Considerable avalanche danger

Published:
Increasing avalanche danger during the day. A new front is expected to bring a lot of snow above tree line. Avoid larger slopes as avalanches easily could be triggered. Natural triggered avalanshes can occur.

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).

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)

Thursday 27. January 2022

Lavlandet bærer preg av mildvær den siste tiden.
I høyfjellet over ca. 1200 moh. består snøoverflaten av fokksnø med varierende hardhet, i vindutsatt terreng er det avblåst til bakken eller skare.

Det gamle snødekket antas stabilt etter flere runder med mildvær.

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

Kraftige snøbyger og vind vil utover dagen gi økende skredfare.
Snøgrensen ventes å synke og skredproblemet vil finnes over tregrensen i heng med fersk snø som er bundet i flak.
Det ventes mest snø i Sunndalsfjella og problemet vil være størst her. Utover dagen ventes det å være lett å løse ut store skred i noen heng. Klassiske skredbaner som får stor pålagring vil også ha fare for naturlig utløste skred.
