Avalanche warning for region Nord-Troms Sunday 17.01.2021

Danger level 2 - Moderate avalanche danger

Published:
Avoid avalanche terrain with newly deposited wind slabs. The wind slabs are overlying a persistent weak layer, and avalanches can therefor be easier to trigger and get bigger than if persistent weak layers were absent.

Avalanche problems

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 16. January 2021

Det er generelt lite snø i regionen. Snøoverflata består i hovudsak av is og skare. I skjerma terrengformasjonar har det lagt seg litt fokksnø. Ryggar og andre terrengformasjonar er avblåst.

Under is og skare er det eit vedvarande svakt lag av kantkorn.

Laurdag vart det observert drønn grunna kollaps i kantkornlaget.

Sunday 17. January 2021

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

Vindpåverka snø vil ha stabilisert seg relativt godt, men det vil ikkje vedvarande svake lag som ligg under. Skred kan difor løysast ut i leheng der snø har samla seg dei siste dagane. Skred på vedvarande svake lag er lettare å løyse ut enn om slike lag var fråverande, men det er ikkje så mykje overliggande snø og difor vil ikkje skred bli så store. Fjernutløysing av skred er mogleg.
