Avalanche warning for region Trollheimen Wednesday 01.01.2020

Danger level 2 - Moderate avalanche danger

Published:
Be careful in areas with wind deposited snow at high elevations. Increasing temperature will weaken the snow cover temporarily.

Avalanche problems

Wind drifted 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).

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

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.

Det har vore mykje nedbør og sterk vind siste dagane som har gjeve stor pålagring i austlege og søraustlege leområder. Siste døgnet har nedbøren under 700 moh kome som regn på snødekket.

Det er tysdag observert gjentatte drønn med god forplantning der våte kantkorn svikter under nysnøen søraust for Sæthøa. Aust for Finnpiggan er det òg observert drønn i snøen, og brot i kantkorn ved bakken.

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

Pågåande kraftig vind frå vest og litt ny nedbør vil gje pålagring i austlege leområder. Det ligg ferske og eldre fokksnøflak i austlege leområder som treng tid på å stabilisere seg. Skred i desse kan verte store.

Stadvis kan flak ligg på svakt lag kantkorn, men utbreiinga av dette er førebels ukjent

Stigande temperatur vil gje svekking av snødekket.
