Avalanche warning for region Trollheimen Saturday 25.12.2021

Danger level 3 - Considerable avalanche danger

Published:
The danger level will increase to considerable (level 3) due to percipitation in combination with strong winds. Avoid leeward slopes.

Avalanche problems

New snow (slab avalanches)

Avalanches may release spontaneously 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.

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

Kraftige snøbyger fra nordvest kan sammen med vind raskt danne ustabile nysnøflak. Disse flakene vil være svært lette å påvirke for en skiløper mens bygene pågår. Bygevær gir store lokale forskjeller. Det er Sunndalsfjella som er mest utsatt. Der det kommer lite nysnø eller det ikke blåser, vil det være vanskeligere å løse ut skred i nysnøen.
