Avalanche warning for region Nord-Troms Friday 12.03.2021

Danger level 2 - Moderate avalanche danger

Published:
Be careful in areas with fresh wind deposited snow. Be aware that persistent weak layers are present in the snowpack and large avalanches can be triggered.

Avalanche problems

Persistent weak layer (slab avalanches)

You can trigger avalanches on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Buried weak layer of faceted snow beneath a crust

Wind drifted snow (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).

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 11. March 2021

Der vinden ikke kommer til, for eksempel i skogen, så er snøen ubunden eller lett vindpåvirket. I høyden og på mer utsatte steder, så er snøen vindpåvirket, eller avblåst til eldre skarelag.

I høyden finnes det flere vedvarende svake lag av kantkorn i forbindelse med skarelag. Det er observert begynnende kantkorndannelse i overgangen mellom gammel smelteomvandlet snø og nysnø. Under ca. 500 moh. er snødekket gjennomfuktet etter mildværet i slutten av februar, men det ligger også en tykk skare over svakt lag opp til ca. 700 moh.

Tirsdag ble det observert noen middels store skred ved nordsiden av Kåfjorden.

Mountain weather

Thursday 11. March 2021

No precipitation. Strong breeze from south, changing to gale from the south during renoon. -18 °C to -8 °C at 1100 m a.s.l. Partly cloudy.

Friday 12. March 2021

No precipitation. Strong breeze from southeast, changing to fresh breeze from the southeast during renoon. -16 °C to -10 °C at 1100 m a.s.l. Partly 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

Det er mulig å løse ut store skred på vedvarende svake lag. De svake lagene ligger dypt i snødekket som gjør at de er vanskelige å påvirke, men vær forsiktig i overgangen mellom tynt og tykt snødekke.

Vinden avtar, fokksnøen får tid til å stabilisere seg, men det kan fortsatt være lett å løse ut skred i fokksnøen i enkelte heng.
