Avalanche warning for region Trollheimen Tuesday 07.02.2023

Danger level 2 - Moderate avalanche danger

Published:
Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Especially where the 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 some steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Buried weak layer of new snow

Wet snow (loose snow 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)

Loose 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)

Monday 6. February 2023

Det er mulig å finne myk snø i skjermede formasjoner og i skogen. I fjellet har vinden tatt slik at snødekket nå er generelt vindpåvirket over skoggrensen. Det er generelt mindre snø enn vanlig i regionen, særlig på rygger og vindutsatte steder.

Det har vært stor temperaturgradient høyt i snødekket onsdag til fredag sist uke og rimkrystaller har vært observert i snøoverflaten. Ny snø kan stedvis ha lagt seg oppå disse.

Mountain weather

Monday 6. February 2023

No precipitation. Fresh breeze from southwest, changing to strong breeze from the southwest during renoon. -6 °C to 1 °C at 1400 m a.s.l. Partly cloudy.

Tuesday 7. February 2023

2-5 mm precipitation. Rain up to 1200 m a.s.l Tuesday night. Moderate gale from southwest, changing to fresh breeze from the southwest during renoon. -8 °C to 1 °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

Vind og noe nysnø vil danne ferske fokksnøflak i høyfjellet. Disse vil i hovedsak ligge i øst og nord, men kraftig vind og lokale forskjeller gjør at det kan finnes ustabile flak i flere himmelretninger. Stedvis kan flakene være lette å løse ut.
Mildere vær kan gi små våte løssnøskred i bratt terreng.
