Avalanche warning for region Trollheimen Saturday 23.01.2021

Danger level 2 - Moderate avalanche danger

Published:
Locally unstable conditions. A skier or a snow mobile may trigger avalanches in the fresh wind slabs, while persistent weak layers deeper in the snow in general is hard to trigger.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Poor bonding between layers in wind deposited snow

Persistent weak layer (slab avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches can get large enough to bury or even kill you (size 2). Remote triggering is possible.

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)

Friday 22. January 2021

Snøoverflata varierer mellom vindpakka hard, vindpakka mjuk, laus snø i forsenkningar og skare. Snøen er fordelt ujevnt i terrenget. I skogen er det mjuk snø og godt skiføre. Ryggar og utsette formasjonar er delvis avblesne.

Klårvær og utstråling frå snødekket etter nyttår danna kantkorn og rim i overflata stort sett overalt. Det ligg no nedføyka kantkorn i store deler av regionen, ofte over skarelag.

Mountain weather

Friday 22. January 2021

2 mm precipitation, up to 10 mm in the most exposed areas. Strong breeze from south, changing to breeze from the south during renoon. -8 °C to -4 °C at 1400 m a.s.l. Cloudy.

Saturday 23. January 2021

2-6 mm precipitation. Breeze from southwest, changing to fresh breeze from the south during the evening. -10 °C to -5 °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

Enkelte stader kan det vere lett å løyse ut skred i leheng med mjuke fokksnøflak - også i skogen. Gamle fokksnøflak på vedvarande svake lag i snødekket kan løysast ut, særlig der fokksnøflaka er tynne.

Ver merksam på fareteikn som drønn og skytande sprekkar. Tynt snødekke og oppstikkande stein gjer at sjølv mindre skred kan gjere stor fysisk skade.
