Avalanche warning for region Indre Troms Thursday 17.02.2022

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).

Buried weak layer of faceted snow above a crust

Persistent weak layer (slab avalanches)

You can trigger avalanches on a few steep slopes. Avalanches can get large enough to bury a large truck or destroy several houses (size 4).

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 16. February 2022

Snøbyger søndag og mandag la igjen mye snø enkelte steder. I skogen er det mye ubunden snø, dette gjelder også til fjells, men enkelte steder over skoggrensa kan snøen være mer vindpåvirket.

Forrige uke var det påbegynnende 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.

Mountain weather

Wednesday 16. February 2022

No precipitation. Fresh breeze from southeast, changing to strong breeze from the southeast. -18 °C to -11 °C at 1100 m a.s.l. Partly cloudy.

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.

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

Østavinden fortsetter første del av dagen og øker skredfaren i leheng med ferske fokksnøflak. Her kan det være lett for skiløper å påvirke fokksnøen, særlig om den ligger på et lag overflaterim som kan ha dannet seg enkelte steder de siste dagene. Ett og annet naturlig utløst skred kan også forekomme. Vinden avtar utover dagen, og dermed også skredfaren.

Det er ingen ferske observasjoner av vedvarende svake lag, og dermed en del usikkerhet rundt hvor aktive kantkornlag i det gamle snødekket er. Men vær særskilt obs på faretegn som drønnelyder og skytende sprekker som tyder på at disse lagene er aktive.
