Avalanche warning for region Trollheimen Thursday 10.02.2022

Danger level 3 - Considerable avalanche danger

Published:
Avoid 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 there.

Avalanche problems

Wind drifted snow (slab avalanches)

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

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 9. February 2022

Det har kommet mye snø den siste tiden og det er nå mer snø enn vanlig for årstiden. Kraftig vind fra sør, sørvest og vest har gitt et vindpåvirket snødekke, og mye snø i leheng mot øst og nord. Utsatte rygger er avblåst til skare. Beskyttede områder har myk snø. I skogen er det myk snø, fuktig og tung der mildværet har tatt.

Mountain weather

Wednesday 9. February 2022

10 mm precipitation, up to 20 mm in the most exposed areas. Rain up to 200 m a.s.l during the evening. Strong breeze from southwest. -10 °C to -5 °C at 1400 m a.s.l. Partly cloudy.

Thursday 10. February 2022

15 mm precipitation, up to 25 mm in the most exposed areas. Rain up to 200 m a.s.l Thursday night. Strong breeze from west. -12 °C to -6 °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

Nysnø og kraftig vind fra vest danner ferske fokksnøflak i leheng mot øst.
Relativt mildt vær gir et snødekke som stabiliserer seg raskt, men vind og nysnø gir konstant påfyll av fersk fokksnø som kan være lett å løse ut. Unngå bratte leheng. Sprekker i fokksnøen er tydelige faretegn.
