Avalanche warning for region Vest-Finnmark Thursday 07.04.2022

Danger level 3 - Considerable avalanche danger

Published:
Complex situation with persistant weak layers. Avalanches are triggered most easily where the wind slabs are thin, typically close to ridges and on convex formations. Remote triggering from less steep terrain is possible.

Avalanche problems

Persistent weak layer (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3). Remote triggering is possible.

Buried weak layer of faceted snow near surface

Wind drifted snow (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).

Poor bonding between layers in wind deposited snow

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 6. April 2022

Tirsdag og onsdag var det kraftig vind fra nordøst. Mange steder er snøoverflaten avblåst til skare, med harde til myke fokksnøflak i skjerma terrengformasjoner. Gammelt snødekke er smelteomvandlet.

I overgangen mellom tørr snø og eldre smelteomvandlet snø (mildværsskare) har det utviklet seg et vedvarende svakt lag med kantkornet snø. Dette er observert flere steder i regionen, men utbredelsen er noe usikker.

Tirsdag kveld gikk et lite skred på Fv.8028 ved Kvalsundet. Onsdag fjernutløste skiløpere et ca 100 m bredt skred på ca 400 moh ved Koppartind.

Mountain weather

Wednesday 6. April 2022

5 mm precipitation, up to 15 mm in the most exposed areas. Precipitation as snow. Moderate gale from northeast, changing to fresh breeze from the northeast during the evening. -9 °C to -4 °C at 1100 m a.s.l. Cloudy.

Thursday 7. April 2022

3-6 mm precipitation. Precipitation as snow. Fresh breeze from east. -8 °C to -4 °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

Det finnes vedvarende svake lag i snødekket som kan påvirkes av skiløper/skuter. Stabiliteten til det vedvarende svake laget varierer over korte avstander, derfor vil fravær av faretegn ikke nødvendigvis bety at det er trygt. Et brudd i slike lag kan forplante seg over avstand. Skred kan derfor fjernutløses.

Vær spesielt forsiktig i leområder der det ligger fokksnø fra de siste dager.
