Avalanche warning for region Ofoten Saturday 29.01.2022

Danger level 2 - Moderate avalanche danger

Published:
Locally unstable conditions. Avoid lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Especially where the wind deposited slabs are thin or soft, a slab avalanche is easier to trigger there. Avalanches on persistent weak layers are in general hard to trigger.

Avalanche problems

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

Persistent weak layer (slab avalanches)

You can trigger avalanches on a few steep slopes. Avalanches can get large enough to bury a large truck or destroy several houses (size 4).

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 28. January 2022

Snøen er svært ujevnt fordelt, og kraftig vind tidligere i uken flyttet på mye snø. På utsatte plasser er det avblåst, mens store mengder fokksnø har samlet seg til myke flak i leområder og beskyttete terrengformasjoner. I skogen er snøoverflaten løsere og nysnøen mindre bundet.

Det gamle snødekket er gjennomfuktet, og mange steder er det et markant skille mellom den nye, tørre snøen fra denne uken og det gamle, fuktige snødekket.

Nye vedvarende svake lag av kantkorn er under utvikling høyt i snødekke rundt skarelag dannet sist helg - men ingen observasjoner som tilsier at det utgjør en skredproblem i per nå.

Over 700-800 moh er eldre vedvarende svake lag av kantkorn fremdeles intakte, men de ligger under massive is- og skarelag.

Fredag er det observert skytende sprekker i den ferske fokksnøen

Mountain weather

Friday 28. January 2022

6 mm precipitation, up to 12 mm in the most exposed areas. Precipitation as snow. Fresh breeze from northwest, changing to breeze from the southeast during the evening. -12 °C to -7 °C at 1100 m a.s.l. Partly cloudy.

Saturday 29. January 2022

1-4 mm precipitation. Precipitation as snow. Strong breeze from southeast, changing to gale from the southeast during renoon. -16 °C to -8 °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

Kraftig vind vil føre til at det dannes ferske flak av vindtransportert snø i leområder. Noen steder kan det være lett for en skikjører å løse ut middels store skred i den ferske, vindtransporterte snøen.

Skred på kantkornlag dypere i snødekket er generelt vanskelig å løse ut.
