Avalanche warning for region Trollheimen Wednesday 01.02.2023

Danger level 2 - Moderate avalanche danger

Published:
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 here.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily 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)

Tuesday 31. January 2023

Snødekket er preget av mildvær og regn i lavlandet, snø og kraftig vind over 400-600 moh.

Det er generelt veldig lite snø, og det er mye oppstikkende stein, særlig på rygger og vindutsatte steder.

Mandag ble det observert ett naturlig utløst vått flakskred i lavlandet i Sunndalen.

Tirsdag formiddag rapporteres det om 20-30 cm nysnø i regionen.

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 kan fortsatt være lett å løse ut middels store skred i leheng som har samlet snø de siste dagene. Mest utsatt er heng mot øst. I enkelte heng, som har samlet mest snø, kan skredene bli store. Fokksnøen vil gradvis stabilisere seg, og utbredelsen av skredproblemet avtar.

I terreng der vinden ikke har fått tak kan det være mye løs, ubunden snø. Her kan det være lett å løse ut løssnøskred opp til middels størrelse. Om sola skulle titte frem kan enkelte små skred løsne naturlig i løssnøen.
