Avalanche warning for region Trollheimen Monday 15.03.2021

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 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 14. March 2021

Snøoverflata ber preg av kraftig vind og i mange himmelretningar er det no harde fokksnøflak. Vinden har tatt eit godt stykke ned i skogen. I sørvendt og bratt terreng tek sola godt. Den eldre snøen er jamt over smelteomvandla etter kraftig mildvêr tidleg i mars.

Det nærmer seg normalmengde med snø for årstida.

Vedvarande svake lag frå kuldeperioden i januar er i stor grad nøytralisert opp til ca 1200 moh pga kraftig mildvær. Over denne høgda kan laget framleis vere eit problem nokre stadar.

Det gjekk laurdag eit stort skred under Nonsfjellet i Oppdal. Det var også observert eit stort drønn i snøen vest om Storhornet.

Det er mange stadar store skavlar, spesielt mot aust.

Mountain weather

Sunday 14. March 2021

No precipitation. Breeze from southeast. -12 °C to -5 °C at 1400 m a.s.l. Partly cloudy.

Monday 15. March 2021

8 mm precipitation, up to 20 mm in the most exposed areas. Breeze from northwest, changing to fresh breeze from the northwest during the afternoon. -10 °C to -4 °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

Nedbør og vind frå nordvest vil utover dagen gje snøtransport til søraustlege leheng. Ein lyt også framleis vere merksam på ustabile fokksnøflak mot nordvest frå forrige veke.
