Avalanche warning for region Trollheimen Friday 11.02.2022

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).

Buried weak layer of new snow

Wet snow (loose snow avalanches)

Avalanches may release spontaneously on a few steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Loose 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)

Thursday 10. February 2022

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

Et stort flakskred er observert i en av østsidene ned mot Driva, sør for Oppdal. Gikk sannsynligvis natt til torsdag.

Mountain weather

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.

Friday 11. February 2022

10 mm precipitation, up to 20 mm in the most exposed areas. Rain up to 100 m a.s.l during the evening. Strong breeze from northwest, changing to moderate gale from the west during the evening. -13 °C to -8 °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

Kraftig vind opprettholder skredfaren. Nysnø og vind fra vest, økende utover dagen, danner nye ferske fokksnøflak i leheng mot øst. Mildværet som kommer inn fredag kveld kan svekke snødekket og gi naturlig utløste våte skred og flakskred. Store snømengder i fjellet tilsier at skred kan bli store. Relativt mildt vær gir et snødekke som stabiliserer seg raskt men konstant påfyll skaper nye ustabile flak. Rolige vindforhold på begynnelsen av dagen gir mykere flak, som kan være svært lette å løse ut når de er ferske.
