Avalanche warning for region Nord-Troms Thursday 06.02.2020

Danger level 3 - Considerable avalanche danger

Published:
Wind and fresh snow may give unstable conditions. 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 there. Especially avoid convex terrain.

Avalanche problems

New 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).

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)

Wednesday 5. February 2020

Siden søndag har det vært hovedsakelig vind fra NV og snøbyger. Polart lavtrykk på tirsdag ga kraftig vind og snøfokk fra ulike retninger. Fram til onsdag morgen har det kommet 20-50 cm nysnø siste 3 døgn, mest nord i regionen.

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

Wednesday 5. February 2020

10 mm precipitation, up to 20 mm in the most exposed areas. Strong breeze from northwest. -16 °C to -10 °C at 1100 m a.s.l. Cloudy.

Thursday 6. February 2020

5 mm precipitation, up to 15 mm in the most exposed areas. Gale from northwest, changing to fresh breeze from the northwest during renoon. -14 °C to -9 °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

Fortsatt vind fra V-NV og snøbyger vil gi pålagring i leområder som allerede har fått mye snø de siste dagene. Stedvis kan det være lett å løse ut store skred. Enkelte naturlig utløste skred kan forekomme, særlig første del av dagen.
Nysnøen ventes å stabiliseres relativt raskt, så roligere værforhold utover dagen gir litt avtagende skredfare.
Der snødekket er tynt kan det være mulig å påvirke vedvarende svakt lag av kantkorn, men dette antas å ha liten utbredelse.
