Avalanche warning for region Trollheimen Saturday 26.12.2020

Danger level 2 - Moderate avalanche danger

Published:
Avoid areas with recent wind slabs. The wind is picking up and turns. Snow on the ground will be eroded and deposited in wind sheltered slopes.

Avalanche problems

New snow (slab avalanches)

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

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 25. December 2020

Det ligger 20-50 cm nysnø i fjellet etter flere dager med snøfall. Snøgrensa har gradvis sunket og fredag er det nysnø til havnivå de fleste steder. Det er gammelt snødekke over ca 500 moh. Dette er stort sett smelteomdannet og hardt etter flere runder med mildvær.

Det har vært kantkorndannelse i snødekket, men det vurderes ikke til å være et skredproblem.

Det er observert små personutløste flakskred både på Oppdal og ved Trolltind i Sunndal torsdag og fredag.

I Innerdalen i Sunndal (400moh) har snødybden økt 40 cm de siste dagene.

Mountain weather

Friday 25. December 2020

1-5 mm precipitation. Breeze from northwest, changing to fresh breeze from the southwest during the afternoon. -16 °C to -7 °C at 1400 m a.s.l. Partly cloudy.

Saturday 26. December 2020

1-3 mm precipitation. Fresh breeze from southwest, changing to strong breeze from the southeast during the afternoon. -11 °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

Nysnøflakene som ble dannet i forbindelse med NV vind tidligere i uka stabiliseres gradvis. Når vinden dreier og øker ligger det mye snø tilgjengelig i fjellet. De ferske fokksnøflakene som dannes utover lørdag vil være lette å påvirke og kan gi krevende forhold i fjellet.
