Avalanche warning for region Nord-Troms Sunday 17.12.2023

Danger level 2 - Moderate avalanche danger

Published:
Strong winds and snow will build fresh wind slabs in northerly aspects, later also easterly aspects. These wind slabs are easy to trigger. The increase in weight from newly formed wind slabs will also increase the probability of triggering deeper instabilities. Avoid leeward areas.

Avalanche problems

Persistent weak layer (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2). 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)

Saturday 16. December 2023

Sterk vind, hovedsakelig fra sør, har preget snødekket. Mange steder finner man harde, bærende fokksnøflak. Snødekket er generelt tynt og avblåst. Det ligger bare mindre mengder ubunden snø både i skogen og i skjermete terrengformer som er tilgjengelig for vindtransport.

Det finnes flere vedvarende svake lag i snødekket i ulike dybder. Det finnes kantkorn og begerkrystaller ved bakken, og et kantkornlag over et skarelag. Enkelte steder i høyden er hele snødekke oppbyggende omvandlet. Det mest fremtredende vedvarende skredproblem er nok et svakt lag av kantkorn og overflaterim under den ferskeste fokksnøen.

Mountain weather

Saturday 16. December 2023

6-8 mm precipitation. Rain up to 100 m a.s.l during the evening. Fresh breeze from south, changing to gale from the south during the afternoon. -15 °C to -4 °C at 1100 m a.s.l. Cloudy.

Sunday 17. December 2023

15 mm precipitation, up to 25 mm in the most exposed areas. Rain up to 200 m a.s.l during the afternoon. Strong breeze from southwest, changing to strong breeze from the west. -8 °C to -3 °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

Fortsatt kraftig vind og nysnø opprettholder skredfaren. Utover ettermiddagen vil vinden dreie, og det dannes ferske fokksnøflak i nye himmelretninger. Flere steder kan de ferske fokksnøflakene legge seg over et svakt lag i overflaten. Det vil være lett å løse ut flakskred for en person, særlig der den ferske fokksnøen er myk.

Faretegn har vært fraværende fra dypereliggende vedvarende svake lag i de siste. Men disse lagene er til stedet og intakt og krever din oppmerksomhet i leheng med fersk pålagring.
