Avalanche warning for region Indre Troms Friday 03.01.2020

Danger level 3 - Considerable avalanche danger

Published:
Be careful in areas with fresh wind deposited snow, Decreasing temperatures reduce the risk of wet avalanches. A persistent weak layer is present but not reactive.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Buried weak layer of new snow

Wet 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).

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)

Thursday 2. January 2020

Torsdag er det forbigåande mildvær opp til ca. 1100 moh, samt nedbør og sterk vind. Ettersom det blir kaldare vil snødekket fryse under mildværsgrensa. Over mildværsgrensa vil snøoverflata sannsynlegvis vere vindpåverka, og fokksnø vil finnast stadig lavare ettersom mildværsgrensa synk.

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.

Mountain weather

Thursday 2. January 2020

18 mm precipitation, up to 40 mm in the most exposed areas. Fresh breeze from south, changing to moderate gale from the southwest during the afternoon. -5 °C to 1 °C at 1100 m a.s.l. Cloudy.

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.

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

Temperaturen blir lavare og det ventast færre våte skred. Fokksnøflak vil dannast stadig lavare og finnast i fleire himmelretningar sidan vinden dreiar. Særleg i høgfjellet i sørvestlege delar av regionen kan det ha samla seg mykje snø i leområder dei siste dagane. Det finnast vedvarande svakt lag av kantkorn djupare i snødekket, men dette verker vanskeleg å påverke.
