Avalanche warning for region Nord-Troms Monday 30.01.2023

Danger level 2 - Moderate avalanche danger

Published:
Locally unstable conditions. A skier or a snow mobile may trigger avalanches in the fresh wind slabs, while persistent weak layers deeper in the snow in general is hard to trigger.

Avalanche problems

Wind drifted snow (slab avalanches)

You can 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 car or destroy a small house (size 3).

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)

Sunday 29. January 2023

Fredag gikk et nytt mildvær forbi regionen med regn til ca 700 moh. Kaldere temperaturer i etterkant har dannet stedvis hard skare eller porøs gjennomslagsskare. Nysnø og vind har også dannet fokksnøflak over skare i le-formasjoner.

Det finnes vedvarende svake lag av kantkorn nær bakken fra november. Stedene der dette er aktivt er imidlertid begrenset etter at snøoverflaten har vært vindherjet de foregående ukene.

Onsdag ble det observert begynnende kantkorndannelse i forbindelse med skarelagene høyere i snødekket.

Mountain weather

Sunday 29. January 2023

10 mm precipitation, up to 18 mm in the most exposed areas. Rain up to 100 m a.s.l during renoon. Gale from northwest, changing to breeze from the southwest during the afternoon. -15 °C to -4 °C at 1100 m a.s.l. Partly cloudy.

Monday 30. January 2023

Little to no precipitation. Breeze from southeast. -12 °C to -6 °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

Det er ventet en dag med roligere vær, og fokksnø dannet de siste dagene vil gradvis stabilisere seg og være vanskelig å påvirke for en enkelt skikjører.

Om belastningen på det vedvarende svake kantkornlaget dypere i snødekket blir stor nok (f.eks. ved at det løsner mindre skred i fokksnøen) kan det også gå naturlig utløste store skred på dette laget noen få steder. Fjernutløsning på dette laget kan fortsatt være mulig.
