Avalanche warning for region Indre Troms Friday 18.02.2022

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. There is also week layers deeper in the snowpack, but they are generally hard to trigger.

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).

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

You can trigger avalanches on a few 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)

Thursday 17. February 2022

Forrige snøfall var i starten av uken. I skogen er det mye ubunden snø, men over tregrensen har vinden onsdag og torsdag blåst bort mye av den løse snøen og fått frem gammel skare eller hard fokksnø på eksponerte plasser.

Det finnes kantkorn rundt skaren fra siste mildvær 23. januar. Det finnes også svake lag av kantkorn og begerkrystaller dypt i snødekket nært bakken. Disse ligger mange steder under harde flak og skare.

Meldes om moderat snøfokk torsdag formiddag.

Mountain weather

Thursday 17. February 2022

1-4 mm precipitation. Precipitation as snow. Strong breeze from east, changing to fresh breeze from the east during the afternoon. -16 °C to -10 °C at 1100 m a.s.l. Cloudy.

Friday 18. February 2022

2-4 mm precipitation. Precipitation as snow. Breeze from northeast. -13 °C to -8 °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

Fredag avtar vinden noe. Fokksnøen vil stabilisere seg gradvis, men det vil fortsatt være lett for skiløper å påvirke fokksnøen i noen heng, særlig om den befinner seg over et lag med overflaterim.

Vedvarende svake lag som finnes dypere i snødekket har vært lite aktivt den siste tiden. Men vær særskilt obs på faretegn som drønnelyder og skytende sprekker som tyder på at disse lagene er aktive.
