Avalanche warning for region Vest-Finnmark Sunday 17.04.2022

Danger level 3 - Considerable avalanche danger

Published:
Large naturally released avalanches are possible. Rain and high temperatures give a higher risk of wet loose snow and slab avalanches on steep terrain. A persistent weak layer is present in the snowpack.

Avalanche problems

Wet snow (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).

Buried weak layer of faceted snow near surface

Wet snow (loose snow avalanches)

You can easily trigger avalanches 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)

Saturday 16. 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.

Fredag ble det observert et str 3 naturlig utløst skred ved Alta.

Natt til lørdag har det vært nattefrost i regionen.

Mountain weather

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.

Sunday 17. April 2022

2 mm precipitation, up to 8 mm in the most exposed areas. Rain up to 1000 m a.s.l during the afternoon. Fresh breeze from west, changing to fresh breeze from the southwest during the afternoon. -3 °C to 1 °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

Nedbør som regn og temperaturøkning vil svekke snødekket og fare for skred vil øke.

Hvis fuktighet når ned til svakt lag vil skred kunne løsne naturlig. Om eller når dette skjer er avhengig av hvor fort temperaturen stiger og mengde regn som kommer.

I høyden kan 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.
