Avalanche warning for region Vest-Finnmark Thursday 05.01.2023

Danger level 2 - Moderate avalanche danger

Published:
The snowpack is complex. There is persistent weak layers buried in the snow pack. Weak layers are mainly covered by hard windslabs, but if they collapse avalanches can become large. Remote triggering possible. Be also careful if you find fresh wind deposited snow.

Avalanche problems

Persistent weak layer (slab avalanches)

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

Buried weak layer of faceted snow beneath a crust

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

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)

Wednesday 4. January 2023

I fjellet er det stort sett vindpåvirket og hard overflate etter kraftig vind i romjula. I skogen og skjermede formasjoner er det mykere snøoverflate.

Dypere i snødekket finnes lag av kantkorn som ble danna i november og første del av desember. Laget er tilstede i de områdene som har hatt snø siden november. Etter kraftig vind i romjula ligger vedvarende svake lag under hard fokksnø mange steder.

Tirsdag ble det observert drønn omkring skoggrensa.

Mountain weather

Wednesday 4. January 2023

Little to no precipitation. Breeze from southeast. -22 °C to -10 °C at 1100 m a.s.l. Clear skies.

Thursday 5. January 2023

No precipitation. Calm/light breeze from southeast. -25 °C to -14 °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

Vedvarende svake lag finnes i snødekket og gjør det utfordrende å vurdere skredfaren. Generelt er det vanskelig å påvirke svake lag høyt til fjells siden snødekket mange steder er ganske vindherjet og hardt. Men i noen få heng kan det fortsatt være lett å løse ut skred. Skred løses lettest ut der fokksnøflak er tynne eller myke.

Rolige værforhold fører til at snøen på overflaten stort sett får ligge i ro. Men hvis det blir litt snøfokk enkelte steder, vil det dannes små ustabile fokksnøflak i leområder.
