Avalanche warning for region Vest-Finnmark Monday 16.01.2023

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.

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 or even kill you (size 2).

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)

Sunday 15. January 2023

Det er kommet opp til 10 cm nysnø før helgen (mest i indre strøk) og ingen nedbør av betydning over helgen.

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

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. Utbredelsen er dog uvisst.

Mountain weather

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.

Monday 16. January 2023

2-3 mm precipitation. Precipitation as snow. Breeze from southeast, changing to fresh breeze from the south during the evening. -14 °C to -7 °C at 1100 m a.s.l. Partly 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

Fokksnøen fra tidligere i helgen vil ha stabilisert seg ytterlige. Vær oppmerksom at i enkelte steder med nedføyket overflaterim vil det fortsatt være mulig å løse ut skred.

De svake lagene lenger nede i snødekket er stort sett vanskelig å løse ut siden de ligger for det meste under harde fokksnøflak. Det er mulig å løse ut store skred der disse fokksnøflakene er myke, eller ligger over kuler og konvekse terrengformer.
