Avalanche warning for region Trollheimen Friday 04.12.2020

Danger level 2 - Moderate avalanche danger

Published:
Be careful in areas with recent wind slabs. Wind from southeasterly direction will still strong enough to erode snow on the ground and deposit it in sheltered slopes and couloirs.

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).

Poor bonding between layers in wind deposited 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)

Thursday 3. December 2020

Eit snøfall i starten av veka ga tørr laussnø frå om lag 500 moh og opp forbi tregrensa. Derfrå var snøen gradvis meir vindpåverka. Frå onsdag auka vinden, slik at overflata no vil vere generelt hardare og snødekket meir ujamt fordelt i terrenget.

Det er generelt gode bindingar mellom lag i underliggande snø.

Torsdag morgon var det -2 °C på Reinsfjellet (990 moh) i Gjemnes. Det bles 14 m/s frå søraust.

Mountain weather

Thursday 3. December 2020

0-3 mm precipitation. Moderate gale from southeast. -8 °C to -4 °C at 1400 m a.s.l. Cloudy.

Friday 4. December 2020

No precipitation. Strong breeze from southeast. -10 °C to -5 °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

Vinden minkar litt og held seg på søraustleg retning. Det er framleis forhold for vindtransportert snø, men ikkje like kraftig som tidlegare i veka. Skredfaren minkar litt og færre heng er utsett. Der snødekket er samanhengande, kan ein løyse ut middels store skred i fersk fokksnø.
