Avalanche warning for region Trollheimen Tuesday 23.03.2021

Danger level 2 - Moderate avalanche danger

Published:
Be careful in areas with fresh wind deposited snow. Wet avalanches can occur where the snow is wet. Be careful beneath and in the vicinity of cornices.

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).

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

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

Buried weak layer of faceted snow near surface

Wet snow (loose snow avalanches)

on some 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)

Tuesday 23. March 2021

Snøvær søndag har lagt att mykje laus snø i skogen. Over skoggrensa er mykje snø blåst inn i austvendte leformasjonare. Mildvér laurdag fukta snøoverflata opp mot 1000 moh.
Det nærmar seg normal snømengde for årstida.

Over 1100 moh. kan svake lag djupt i snødekket framleis vere eit problem i nokre heng.

Både middels store laussnøskred og store flakskred vart observert i Storlidalen på mandag.

Mange ryggar og egger har store skavlar på austleg side. Drønn med god forplantning vart observert på Okla i Oppdal fredag.

Mountain weather

Monday 22. March 2021

4 mm precipitation, up to 10 mm in the most exposed areas. Moderate gale from west, changing to fresh breeze from the west during the afternoon. -5 °C to -1 °C at 1400 m a.s.l. Cloudy.

Tuesday 23. March 2021

Little to no precipitation. Fresh breeze from west. -3 °C to 2 °C at 1400 m a.s.l. Partly 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

Vind frå vest fortset å flytte snø inn i austvendte leformasjonar. I bratte heng med fersk fokksnø kan ein skikøyrar løyse ut skred. Gradvis temperaturstiging utover dagen og varmegrader høgt til fjells virkar stabiliserande på fokksnø. Men varmen kan svekke skavlar og føre til skavlbrudd. Der sola bryt gjennom skydekket kan det gå våte skred frå sørvendte brattheng.
Høgt til fjells kan svake lag av kantkorn djupt i snødekket framleis påvirkast i enkelte heng der snødekket er tynt eller mjukt.
