Avalanche warning for region Salten Saturday 09.12.2017

Danger level 3 - Considerable avalanche danger

Published:
Locally unstable conditions due to wind slabs in lee areas. A weak layer of facets may also be triggered where the snow cover is thin.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Poor bonding between layers in wind deposited snow

Persistent weak layer (slab avalanches)

You can trigger avalanches 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.

Snow cover (in Norwegian)

Friday 8. December 2017

Vind opp i storm styrke har flyttet på det meste av snø i fjellet. Overflaten veksler mellom hard fokksnø og avblåste partier.

Kantkornlaget dypere i snødekket ligger nå under fokksnø.

Ingen skredaktivitet observert.

Det er store variasjoner på snømengdene i regionen og på hardheten av snøoverflaten.

Mountain weather

Friday 8. December 2017

0 mm precipitation, up to 5 mm in the most exposed areas. Strong gale from southeast. -13 °C to -7 °C at 1400 m a.s.l. Cloudy.

Saturday 9. December 2017

0 mm precipitation, up to 8 mm in the most exposed areas. Moderate gale from southeast. -10 °C to -5 °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

Den kraftige vinden fortsetter, og indre strøk får noe ny nedbør. Det vil være en del snøtransport men snøoverflaten er allerede vindpakket i store deler av regionen. Det kan finnes ustabile fokksnøflak i leformasjoner og skredfaren vil være størst der nedbøren treffer (indre strøk). Kantkornlag vil mange steder ligge under hard fokksnø men kan trigges der snødekket er tynt eller mykt.

Skredfaren ventes som 3-betydelig, men er minkende.
