Avalanche warning for region Trollheimen Monday 28.12.2020

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.

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).

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)

Sunday 27. December 2020

Kraftig vind søndag har flyttet mye av den løse snøen og dannet flak av ulik hardhet. I skogen kan snøen være fuktig som følge av høye temperaturer. Det gamle snødekket er stort sett smelteomdannet og hardt etter flere runder med mildvær. Det er fortsatt tynt snødekke i regionen. Under 500 moh er det lite såle.

Det har vært kantkorndannelse i snødekket, men det vurderes ikke til å være et skredproblem.

Ved Trolltind i Sunndal ble det observert både personutløste og naturlig utløste skred fredag og lørdag.

Søndag er det 6 grader i Innerdalen (400 moh)

Mountain weather

Sunday 27. December 2020

1 mm precipitation, up to 8 mm in the most exposed areas. Moderate gale from southeast, changing to gale from the southeast during the afternoon. -7 °C to -2 °C at 1400 m a.s.l. Cloudy.

Monday 28. December 2020

Little to no precipitation. Moderate gale from southeast. -9 °C to -4 °C at 1400 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

Gunstige temperaturer stabiliserer fokksnøen og den blir vanskeligere å påvirke. Selv om den kraftige vinden opprettholdes er det mindre snø å flytte på. En skiløper vil fortsatt kunne løse ut skred i de ferskeste fokksnøflakene.
