Avalanche warning for region Vest-Finnmark Thursday 16.12.2021

Danger level 1 - Low avalanche danger

Published:
Fresh wind slabs will likely be small but touchy. Hard slabs can still be triggered in a few sheltered locations, especially when they have got fresh slab on top. Beware of terrain traps and thin snow with lots of rocks.

Avalanche problems

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)

Buried weak layer of new 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).

Buried weak layer of faceted snow near surface

Wet snow (loose snow avalanches)

Avalanches may release spontaneously 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 15. December 2021

Snøoverflaten over skoggrensa er mange steder vindpakket og hard, mens det noen steder rundt skoggrensa er mykere fokksnøflak. Nord i regionen er det mye avblåst og generelt lite snø.

Fokksnøflakene ligger mange steder på nedføyket kantkorn fra kuldeperioden i slutten av november. Dypere i snødekket ligger det også et svakt lag av kantkorn under et skarelag som ble dannet av mildvær i midten av november.

Mountain weather

Wednesday 15. December 2021

Little to no precipitation. Strong breeze from southeast. -15 °C to -4 °C at 1100 m a.s.l. Partly cloudy.

Thursday 16. December 2021

5 mm precipitation, up to 10 mm in the most exposed areas. Rain up to 400 m a.s.l during renoon. Breeze from southwest, changing to breeze from the southeast during the evening. -7 °C to -2 °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

Små fokksnøflak vil bygge seg opp i skjermete formasjoner i løpet av dagen. Skred i den ferske snøen forventes i stort sett å bli små.

Under den ferske snøen ligger gamle harde flak på et svakt lag av kantkorn. Noen få steder der pålagringen er størst kan det svekke disse lagene. Det kan ikke utelukkes at det er mulig å løse ut store skred her. Dette vil være mest utpreget høyt til fjells i bratte, snøsamlende formasjoner der det tidligere vært tynt, men sammenhengende snødekke.

Lavere til fjells og fremfor alt i og under skoggrensen vil sludd og etter hvert regn gi noen små våte løssnøskred utover dagen.
