Avalanche warning for region Nord-Troms Saturday 08.02.2020

Danger level 2 - Moderate avalanche danger

Published:
Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Especially where the wind deposited slabs are thin or soft, a slab avalanche is easier to trigger here.

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).

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 7. February 2020

Starten av uken var preget av snøbyger og vind fra NV. Over tregrensa er snødekket vindpakket og består for det meste av harde fokksnøflak, utsatte steder er det avblåst ned til gammelt skarelag. Fredagens vind fra V og mildvær har dannet myke flak.

Det er observert lag med kantkorn over/under skarelag noen steder i regionen. Dette ligger nå stort sett dypt i snødekket under hard fokksnø og er dermed vanskelig å påvirke.

Mountain weather

Friday 7. February 2020

4 mm precipitation, up to 10 mm in the most exposed areas. Fresh breeze from south, changing to moderate gale from the west during renoon. -12 °C to -2 °C at 1100 m a.s.l. Cloudy.

Saturday 8. February 2020

Little to no precipitation. Strong breeze from west, changing to breeze from the southwest during the evening. -5 °C to 0 °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

Vestlig vind vil flytte snø inn i leområder, men denne fokksnøen ventes å stabiliseres raskt pga temperaturer nær 0°C. Snødekket under mildværsgrensa vil stabilisere seg raskt, men det vil fortsatt være mulig å løse ut små våte skred.

Der snødekket er tynt kan det være mulig å påvirke vedvarende svakt lag av kantkorn, men dette antas å ha liten utbredelse.
