Avalanche warning for region Indre Troms Tuesday 31.12.2019

Danger level 2 - Moderate avalanche danger

Published:
Be aware of isolated wind slabs above treeline, otherwise stable conditions.

Avalanche problems

Wind drifted snow (slab avalanches)

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

Poor bonding between layers in wind deposited snow

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)

Monday 30. December 2019

Et tynt lag med nysnø ligger over skaren som strekker seg opp til mildværsgrensa fra søndag. Over denne høyden er det varierende snøoverflate etter perioder med kraftig vind.

Under gamle fokksnøflak finnes stedvis svakt lag av kantkorn. Dette ligger vekselvis under, over og mellom porøse skarelag. Stabilitetstester viser at laget under skaren kollapser lett, men siden skarelaget de fleste stedene er hardt og tykt er det stort sett vanskelig å påvirke det. Kantkorn over skare er observert i nærheten av Bardufoss, men ikke i Tamokdalen.

Mountain weather

Monday 30. December 2019

7 mm precipitation, up to 13 mm in the most exposed areas. Gale from west, changing to fresh breeze from the north Monday night. -8 °C to -1 °C at 1100 m a.s.l. Cloudy.

Tuesday 31. December 2019

5-8 mm precipitation. Fresh breeze from west, changing to strong breeze from the northwest during the afternoon. -13 °C to -7 °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

Temperaturen synker ytterligere. Noe ny snø og litt vind vil gi fokksnø i leformasjoner.

Vedvarende svake lag av kantkorn forventes å være svært vanskelig å påvirke på grunn av hard overliggende snø.
