Avalanche warning for region Nord-Troms Wednesday 11.03.2020

Danger level 2 - Moderate avalanche danger

Published:
Be careful in areas with wind-deposited snow, typically behind ridges, ribs and in gullies. Be aware that changing wind directions have caused wind slabs in many aspects.
Persistent weak layers deeper in the snow are in general 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).

Poor bonding between layers in wind deposited 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)

Tuesday 10. March 2020

Opp til ca 700-800 moh ble snøoverflaten fuktet av mildværet mandag. Etter dette har det blitt kaldere med tilfrysing, og mange steder har fått litt nysnø. Høyere opp ligger det fokksnø av varierende hardhet. I vindbeskyttede terrengformasjoner kan det fremdeles ligge ubunden snø.

Det finnes et vedvarende svakt lag av kantkorn under skarelag fra januar, og det er trolig mest fremtredende i indre deler av regionen. Men dette ligger stort sett dypt i snødekket og er vanskelig å påvirke.

Mountain weather

Tuesday 10. March 2020

5 mm precipitation, up to 13 mm in the most exposed areas. Strong breeze from northwest, changing to breeze from the northeast during the afternoon. -12 °C to -4 °C at 1100 m a.s.l. Partly cloudy.

Wednesday 11. March 2020

Little to no precipitation. Moderate gale from southeast, changing to fresh breeze from the southeast during the afternoon. -18 °C to -9 °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

Det ventes kraftig vindøkning fra SØ og det finnes noe snø tilgjengelig for transport. Dette gir pålagring av fokksnø i leheng mot nordvest. Vær oppmerksom på at varierende vindretning de siste dagene fører til at det kan finnes ustabile flak også i andre himmelretninger.
