Avalanche warning for region Nord-Troms Tuesday 20.02.2018

Danger level 1 - Low avalanche danger

Published:
Generally stable conditions, but wind slabs may be present in isolated features. A persistent weak layer is present in the snow-pack, but is not active/able to propagate.

Avalanche problems

Wind drifted snow (slab avalanches)

You can trigger avalanches on a few steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

Poor bonding between crust and overlying 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 19. February 2018

Mildvær i starten av uke 6 førte til dannelse av skare høyt til fjells. I høyden er snødekket generelt preget av avblåst skare og noen lommer med gammel fokksnø. Over 800 moh er det store områder med knallhard, glasert skare som stedvis kan være vanskelig å ta seg frem på. Det har noen steder dannet seg overflaterim.

Det finnes flere godt utviklede kantkornlag i den øverste delen av snødekket, men disse har vist liten evne til brudd-forplantning og utgjør ikke som et problem nå.

Mountain weather

Monday 19. February 2018

No precipitation. Breeze from east. -20 °C to -10 °C at 1100 m a.s.l.

Tuesday 20. February 2018

No precipitation. Breeze from southeast. -23 °C to -11 °C at 1100 m a.s.l. Clear skies.

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

Det ventes ingen endring i skredfaren. Generelt er det stabile forhold, men i noen isolerte leheng kan det finnes små, gamle fokksnøflak som har dårlig binding til skaren under.
