Avalanche warning for region Nord-Troms Saturday 16.12.2023

Danger level 2 - Moderate avalanche danger

Published:
Strong winds from southerly directions and some precipitation as snow over 100 m.a.s.l will build fresh wind slabs in northerly 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

Wind drifted snow (slab avalanches)

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

Poor bonding between layers in wind deposited snow

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)

Friday 15. 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 menger 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

Friday 15. December 2023

Little to no precipitation. Moderate gale from south, changing to fresh breeze from the southwest during the afternoon. -18 °C to -7 °C at 1100 m a.s.l. Partly cloudy.

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.

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 fra sør vil flytte nysnø og det som er tilgjengelig for transport inn i nordvendte heng. Det ventes mest nedbør innerst i Storfjorden. 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.
