Avalanche warning for region Vest-Finnmark Friday 24.12.2021

Danger level 2 - Moderate avalanche danger

Published:
Be careful in areas with fresh wind deposited snow. There may be pockets with a persistent weak layer beneath the wind depposited snow.

Avalanche problems

Wind drifted snow (slab avalanches)

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

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

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

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 23. December 2021

Snødekket varierer i regionen. De to siste dagene har det kommet mye nysnø (20-30cm) sammen med kraftig vind, spesielt i ytre strøk.

Forrige ukes mildvær har dannet skare i eller nært overflaten i det gamle snødekket i lavlandet.

Det er observert vedvarende svake lag av kantkorn dypt i snødekket i høyden, og i forbindelse med skarelaget som ble dannet etter helgens mildvær opp til ca 500 moh.

Tirsdag ble det observert drønn i snødekket. Det er også blitt observert overflaterim i regionen etter den siste kuldeperioden.

Mountain weather

Thursday 23. December 2021

6 mm precipitation, up to 12 mm in the most exposed areas. Precipitation as snow. Moderate gale from northeast. -19 °C to -11 °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

Nytt påfyll av snø vil fortsette å lage ny ustabil fokksnø. Kulden fører til at fokksnøen dannet de siste dagene vil trenge tid for å stabiliseres. Det kan fortsatt være lett å løse ut skred i disse.

Fokksnøen kan flere steder ligge over et ustabilt snødekke med vedvarende svake lag av kantkorn, her kan fjernutløsning være mulig. Se opp for skytende sprekker og drønn, dette er tydelige tegn på at svake lag er tilstede.
