Avalanche warning for region Nord-Troms Saturday 31.12.2022

Danger level 3 - Considerable avalanche danger

Published:
It will still be strong winds throughout the day, but the snow transport will be limited due to the hard snow surface. Avalanches can however be very easy to trigger at some places, directly or remotely, on persistent weak layers. Keep a good distance from avalanche terrain.

Avalanche problems

Persistent weak layer (slab avalanches)

You can very easily trigger avalanches 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.

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 30. December 2022

Snødekket er generelt tynt, men snøen som finnes er ugunstig oppbygd. Snøoverflata i fjellet består av fokksnø som for det meste er hard og mange steder er det avblåst til skare eller mye oppstikkende stein.

Under fokksnøen er det vedvarende svake lag av rim og kantkorn, som ble dannet i starten av desember.

De svake lagene har de siste dagene gitt faretegn som drønn og skytende sprekker.

Mountain weather

Friday 30. December 2022

0-3 mm precipitation. Precipitation as snow. Gale from southeast, changing to moderate gale from the southeast during the evening. -14 °C to -8 °C at 1100 m a.s.l. Cloudy.

Saturday 31. December 2022

3-5 mm precipitation. Precipitation as snow. Moderate gale from southeast. -13 °C to -6 °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 skal fremdeles være mye vind, og etter flere dager med sterk vind fra samme retning vil det ha blitt pålagret mye snø i leheng.

Det kan dermed lett løses ut skred i det ugunstig oppbygde snødekket med vedvarende svake lag. Hvor lett det er å påvirke disse lagene avhenger av tykkelsen og hardheten til overliggende snø. Stedvis kan skred være svært lett å løse ut, også fra avstand.
