Avalanche warning for region Trollheimen Friday 24.12.2021

Danger level 2 - Moderate avalanche danger

Published:
Wind and fresh snow may give instable conditions in some slopes. 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. Avoid convex terrain.

Avalanche problems

New 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)

Thursday 23. December 2021

Det ligger ca 5-20 cm nysnø/fokksnø i terrenget, mest i leområder mot S og Ø. Etter mildvær opp til ca 1500 moh 19. desember er det gamle snødekket smelteomdanna med hard bærende skare. Under ca 600 moh er det lite såle.

Observasjoner onsdag ved Oppdal forteller om løs ubunden snø over skaren som er tilgjengelig ved vindøkning.

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

En skiløper vil kunne løse ut skred i noen få heng med nysnøflak fra torsdag kveld, typisk i le bak rygger og vindutsatte steder. Bygevær juleaften kan lokalt gi ustabile nysnøflak i flere heng utover dagen. Begrenset vind gjør at det er nordlige og kystnære områder som er mest utsatt.
