Avalanche warning for region Trollheimen Thursday 20.01.2022

Danger level 4 - High avalanche danger

Published:
Dangerous avalanche conditions due to large amounts of new snow and strong winds. Natural very large avalanches are likely. Avoid avalanche terrain.

Avalanche problems

New snow (slab avalanches)

Avalanches may release spontaneously on some steep slopes. Avalanches can get large enough to bury a large truck or destroy several houses (size 4).

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 19. January 2022

Det har kommet mye nysnø i regionen. I høyden er snøoverflaten preget av fokksnø med varierende hardhet. I terreng skjermet for vind og i skogen er det stedvis mye løs snø. Vindutsatte områder er avblåst til bakken eller skare. Det gamle snødekket antas stabilt etter "Gyda" og gjenfrysing, unntatt i de høyestliggende områdene.

Observatør melder om flere store og opptil svært store skred i Oppdalsområdet de siste dagene i forbindelse med uvær. Onsdag melder observatør om kraftig snøfokk nord i Trollheimen.

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

Det ventes stedvis mye nysnø og svært kraftig vind. Store mengder ustabil fokksnø gir fare for naturlig utløste skred, som i store lesider kan bli svært store. Midtre og indre deler av regionen er mest utsatt, og bygevær gir lokale forskjeller i nysnømengde.
