Avalanche warning for region Vest-Finnmark Saturday 16.04.2022

Danger level 3 - Considerable avalanche danger

Published:
Be careful in areas with fresh wind deposited snow. Lower, warmer temps might weaken the snowpack. Large human triggered and natural avalanches are possible. Danger signs such as avalanche activity and whoopfs are a clear sign that it is time to give all avalanche terrain a wide berth.

Avalanche problems

Persistent weak layer (slab avalanches)

Avalanches may release spontaneously on a few 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 some steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Buried weak layer of new snow

Wet snow (loose snow avalanches)

Avalanches may release spontaneously on some 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)

Friday 15. April 2022

Det ligger fokksnøflak av ulik hardhet i fjellet, og løsere snø i skjermede heng og i skogen. Opp til ca. 300 moh er overflaten vært fuktet.

I overgangen mellom tørr snø og eldre smelteomvandlet snø (mildværsskare) finnes et vedvarende svakt lag med kantkorn. Dette er observert flere steder i regionen. Generelt virker det vanskelig å påvirke, men i enkelte heng, særlig der flakene er tynnere vil det være lettere.

Onsdag løsnet det mange solutløste skred, både flakskred og løssnøskred.

Mountain weather

Friday 15. April 2022

4 mm precipitation, up to 11 mm in the most exposed areas. Rain up to 300 m a.s.l during the afternoon. Breeze from west, changing to fresh breeze from the west during the afternoon. -8 °C to -3 °C at 1100 m a.s.l. Cloudy.

Saturday 16. April 2022

1 mm precipitation, up to 9 mm in the most exposed areas. Rain up to 400 m a.s.l during the afternoon. Fresh breeze from southwest, changing to gale from the west during the afternoon. -5 °C to 0 °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

I høyden vil nysnø og vind danne ferske ustabile flak i leheng som vil være lett å løse ut. Det er observert begynnende kantkorndannelse i overflaten som kan gjøre at flakene blir ekstra ustabile.

Der nedbøren kommer som regn vil snødekket bli svekket og fare for skred vil øke. Det er knyttet stor usikkerhet til et vedvarende svakt lag med kantkorn og om mildværet vil kunne svekke stabiliteten nok til at store skred kan løsne. Det vil bl.a. avhenge av hvor fort temperaturen stiger og mengde regn som kommer.
