Avalanche warning for region Indre Troms Sunday 10.12.2017

Danger level 2 - Moderate avalanche danger

Published:
Generally stable conditions, but you should still be careful in areas with fresh wind deposited snow. Be aware that there can be pockets with persistent weak layer beneath wind deposited snow.

Avalanche problems

Wind drifted snow (slab avalanches)

You can 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

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 9. December 2017

Det kom store mengder snø i starten av uken. Etter kraftig vind torsdag og fredag er snøoverflaten nå svært vindpåvirket stort sett overalt. Det er fremdeles store variasjoner i snømengder i regionen. Det gamle snødekket under fokksnøen har vært preget av skare og smelteomvandlet snø.

3/12 er det observert svake lag av kantkorn rundt Bardu, men det er ikke veldig potent ennå.

Det er ikke observert aktivitet de 3 siste dagene.

Mountain weather

Saturday 9. December 2017

1 mm precipitation, up to 10 mm in the most exposed areas. Moderate gale from southeast. -13 °C to -6 °C at 1100 m a.s.l. Cloudy.

Sunday 10. December 2017

2 mm precipitation, up to 10 mm in the most exposed areas. Moderate gale from southeast. -8 °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

Den kraftige vinden fortsetter, og det ventes noe ny nedbør i indre strøk. Fokksnøen fra siste dager forventes nå å være hard og beærende i store deler av regionen. Svake lag nede i snødekket er beskyttet av den harde fokksnøen og det skal mye til for å påvirke lagene. Faregraden ventes å ligge på 2-moderat, med størst fare for skred der det finnes myk fokksnø.
