Avalanche warning for region Trollheimen Sunday 28.03.2021

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

Wet 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)

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)

Saturday 27. 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 nærmar seg normal snømengde i fjellet, men under tregrensa nord i regionen er det mange plassar begrensa skiføre .

Over 1100 moh. kan kantkorn rundt skarelag i snødekket fortsatt vere et problem i noen heng, spesielt i områder rundt Oppdal.

Fredag vart det rapportert om drønn i snø 1350 moh. i Oppdal.

Mountain weather

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.

Sunday 28. March 2021

1-3 mm precipitation. Strong breeze from southeast, changing to fresh breeze from the southwest during the afternoon. -13 °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

Skredproblemet finns i fokksnøflak danna dei siste dagane høgt til fjells. Det skal stor tilleggsbelastning til for å påvirke flaka, men i skjerma formasjonar med mjuke flak kan ein enkelt skiløpar løyse ut skred.
I solvendte brattheng kan små (str.1) våte laussnøskred løysast ut der sola bryt gjennom skydekket.
Høgt til fjells kan det i enkelte heng vere svakt lag av kantkorn djupt i snødekket.
