Avalanche warning for region Indre Troms Saturday 04.01.2020

Danger level 3 - Considerable avalanche danger

Published:
Be careful in areas with fresh wind deposited snow, Old persistent weak layers exist in the snow cover, but is hard to trigger.

Avalanche problems

Wind drifted snow (slab avalanches)

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

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 3. January 2020

Torsdag var det forbigåande mildvær opp til ca. 1100 moh, samt nedbør og sterk vind. Dette vil ha påverka snødekket og truleg gitt våt/fuktig snø under mildværsgrensa, som i ettertid har fryst. I fjellet er det vindpåverka snø.

Det er stadvis observert lag med kantkorn over, under og mellom skarelag. Laget kollapsar lett ved tester, men det skal mykje til for å påverke det i terrenget. Dette er observert i området rundt Bardufoss, men ikkje i Tamokdalen.

Onsdag gjekk det nokre våte naturleg utløyste laussnøskred på Storfjellet.

Mountain weather

Friday 3. January 2020

10 mm precipitation, up to 15 mm in the most exposed areas. Fresh breeze from southwest, changing to strong breeze from the west during the evening. -10 °C to -2 °C at 1100 m a.s.l. Partly cloudy.

Saturday 4. January 2020

15 mm precipitation, up to 20 mm in the most exposed areas. Gale from northwest, changing to strong breeze from the northwest during the evening. -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 finnast allereie nysnø- og fokksnøflak i fjellet, og nye vil bli danna når vinden dreier mot NV og gir meir nedbør og vind. Det kan då vere mogleg å løyse ut flakskred i mange himmelretningar og det kan gå skred naturleg grunna stor pålagring. Det finnast vedvarande svakt lag av kantkorn djupare i snødekket, men dette verker vanskeleg å påverke.
