Avalanche warning for region Vest-Finnmark Sunday 15.01.2023

Danger level 2 - Moderate avalanche danger

Published:
Locally unstable conditions. A skier or snowmobile can trigger slab avalanches in fresh wind slabs.

Be also aware that persistent weak layers of faceted crystals, deeper in the snowpack, can be triggered where the overlying wind slabs are thin or soft.
  • The danger is greatest until Sunday afternoon

Avalanche problems

Wind drifted snow (slab avalanches)

You can trigger avalanches on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Poor bonding between layers in wind deposited 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)

Saturday 14. January 2023

Kraftig vind fra forrige helg og til og med tirsdag har flyttet snø inn i nordvendte heng. Sørvendte heng er stort sett avblåst.

Fokksnøflak har lagt seg på tidligere glattpolert fokksnøoverflate eller løssnø. I skogen og skjermede formasjoner er det mykere snøoverflate og stedvis snø tilgjengelig for vindtransport.

De svake lagene av kantkorn, dannet i november, ligger nå under hard fokksnø mange steder.

Enkelte steder dannet det seg overflaterim før siste periode med vind. I enkelte forsenkninger der vind ikke har fått tak, kan disse nå ligge gjemt under innblåst snø.

De siste dagene har det blitt observert drønn og skytende sprekker omkring skoggrensa og over.

Mountain weather

Saturday 14. January 2023

3-6 mm precipitation. Rain up to 100 m a.s.l Saturday night. Breeze from southwest, changing to moderate gale from the southwest during the evening. -15 °C to -6 °C at 1100 m a.s.l. Partly cloudy.

Sunday 15. January 2023

Little to no precipitation. Fresh breeze from southwest, changing to breeze from the southeast during the afternoon. -18 °C to -8 °C at 1100 m a.s.l. Cloudy.

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

Avtagende nedbør fra lørdag natt til søndag gjør at de ferske fokksnøflakene stabiliserer seg utover dagen dog sakte. Både sterk og dreiende vind nedføyket overflaterim enkelte steder (uvisst utbredelse) gjør at stabiliseringen kan ta lenger tid enn forventet.

Der snødekke er tynt, eller terrenget er oppstikkende, kan det være mulig å løse ut skred på svake lag av kantkorn dypt i snødekke.
