Avalanche warning for region Trollheimen Monday 13.03.2023

Danger level 3 - Considerable avalanche danger

Published:
Wind and fresh snow may give instable conditions. 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 there. Especially avoid convex terrain.

Avalanche problems

New 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).

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)

Sunday 12. March 2023

Det har kommet mye snø i regionen den siste uken og områdene rundt Oppdal og Sunndal har nå mer snø en normalt for denne tiden på året. Det ligger en god del tørr løssnø både i skogen og over tregrensen. Gjennom hele uken har det vært lite vind, og snøen har blitt liggende løs og ubunden selv i fjellet. Økende vind i helgen har dannet fokksnøflak i øst og sørvendte heng.

Det er ikke gjort noen tydelige observasjoner på vedvarende svake lag i det siste. Kaldt klart vær vekslende med nysnø kan ha dannet noe. Vær obs på drønn og skytende sprekker.

Mountain weather

Sunday 12. March 2023

3 mm precipitation, up to 13 mm in the most exposed areas. Precipitation as snow. Strong breeze from west, changing to breeze from the southwest during the evening. -20 °C to -9 °C at 1400 m a.s.l. Partly cloudy.

Monday 13. March 2023

4-6 mm precipitation. Rain up to 100 m a.s.l during the afternoon. Moderate gale from southeast, changing to fresh breeze from the north during the afternoon. -12 °C to -6 °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 fra en ny himmelretning vil kunne flytte gjenstående løs snø inn i leheng mot nord. Her kan det være lett for en skikjører å løse ut skred. Vinden roer seg utover dagen men ferske fokksnøflak vil trenge noe tid til stabilisering.

Dersom mildværet går høyere enn meldt kan det gå våte løssnøskred i lavlandet.
