Avalanche warning for region Trollheimen Thursday 17.12.2020

Danger level 1 - Low avalanche danger

Published:
Generally stable conditions, but be careful in steep terrain, especially where 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 are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

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)

Wednesday 16. December 2020

Snødekket er generelt tynt og snøoverflaten varierer mellom å være hard og isete eller litt mykere med overflatekantkorn. Snøgrensen ligger på 500-800 moh. Lavest i indre del av regionen, mest snø i Sunndalsfjella. Lite snø i ytre del av regionen.

Tørt og klart vær har den siste tiden gitt gode forhold for oppbyggende omvandling. Dannelse av overflatekantkorn har mange steder gitt en løsere snøoverflate.

Mountain weather

Wednesday 16. December 2020

Little to no precipitation. Breeze from southwest. -6 °C to -2 °C at 1400 m a.s.l. Partly cloudy.

Thursday 17. December 2020

Little to no precipitation. Moderate gale from south, changing to fresh breeze from the south during the afternoon. -6 °C to -1 °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

Økende vind vil igjen gi noe snøtransport og ferske flakdannelser. Mest utsatt er terreng som samler snø mot nord. Det vil fortsatt være mulig for en skiløper å løse ut mindre skred, spesielt på utsatte plasser, f.eks. i bratt terreng der det nylig har lagt seg inn snø.
Ellers mye hard snøoverflate og generelt stabile forhold.
