Avalanche warning for region Trollheimen Saturday 27.03.2021

Danger level 2 - Moderate avalanche danger

Published:
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 here.

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).

Buried weak layer of new snow

New snow (loose snow avalanches)

on some steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

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 26. March 2021

Etter mildvær tidlig i uka ble nysnøen våt og smelteomdanna opp til 1000-1200 moh. Litt nysnø og kraftig vind over tregrensa onsdag gjør at overflaten består av skare eller tynne fokksnøflak i le for vinden. Det nærmer seg normale snømengder for årstida i fjellet, men under tregrensa nord i regionen, er det begrensa skiføre mange steder.

Over 1100 moh. kan kantkorn rundt skarelag i snødekket fortsatt være et problem i noen heng rundt Oppdal.

Observasjoner fra Åbittind i Sundal forteller om snøfokk i fjellet og harde fokksnøflak. Sola varmer opp skaren i bratte heng.

Mountain weather

Friday 26. March 2021

Little to no precipitation. Moderate gale from south. -8 °C to -1 °C at 1400 m a.s.l. Cloudy.

Saturday 27. March 2021

4-7 mm precipitation. Fresh breeze from south, changing to fresh breeze from the southwest during the afternoon. -8 °C to -1 °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

Skredproblemet finnes i fokksnøflak fra de siste dagene høyt til fjells. I de fleste heng vil det generelt kreves stor tilleggsbelastning for å påvirke flakene, men i skjermede formasjoner med myke flak kan fortsatt en enkelt skiløper løse ut skred.

Høyt til fjells ligger det fortsatt svake lag av kantkorn som kan påvirkes ved stor tillegsbelastning hvis snødekket er tynt eller mykt. Eventuelle skred kan bli store(str.3) .
