Avalanche warning for region Nord-Troms Thursday 14.01.2021

Danger level 2 - Moderate avalanche danger

Published:
Be careful in steep terrain, with fresh wind deposited slabs, especially where there might be a persistent weak layer in the old snow or the old snow has an icy surface

Avalanche problems

Persistent weak layer (slab avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches can get large enough to bury or even kill you (size 2). Remote triggering is possible.

Buried weak layer of faceted snow beneath a crust

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 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)

Wednesday 13. January 2021

Det er generelt lite snø og ikke skiføre under 200-300 moh. Opp til ca 600 moh er det hovedsakelig is eller skare på overflaten. Høyere til fjells finnes stedvis litt fokksnø over tynn skare.

Under skarelaget har det mange steder dannet seg et velutviklet lag av kantkorn som bryter lett på stabilitetstest. I helgen ble det observert små drønn i snødekket over ca 500 moh. Det er foreløpig usikkert hvor stor evne laget har til bruddforplantning. Dette vil kun utgjøre et skredproblem der det ligger flak av fokksnø/nysnø over.

Mountain weather

Wednesday 13. January 2021

No precipitation. Fresh breeze from southeast, changing to breeze from the southeast during the afternoon. -21 °C to -9 °C at 1100 m a.s.l. Partly cloudy.

Thursday 14. January 2021

3-7 mm precipitation. Fresh breeze from northwest. -14 °C to -6 °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

Snøbyger kan føre til ferske fokksnøflak som kan være lette å løse ut, særlig i østvendt terreng. Vær ekstra varsom der fokksnøen ligger over et vedvarende svakt lag av kantkorn eller på glatt skare. Følg nøye med på faretegn som skytende sprekker og drønn i snøen. Mest snø vil komme i ytre strøk.
