Avalanche warning for region Svartisen Thursday 28.12.2023

Danger level 3 - Considerable avalanche danger

Published:
Conditions are challenging. Be sure you have enough knowledge and experience before travelling in steep terrain. Be extra careful in lee areas with wind deposited snow. There are persistent weak layers in the snowpack.

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

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 27. December 2023

Klokka 10 onsdag hadde det kommet 15-35 cm nysnø siste døgn. Det ble målt vind opp i liten kuling på målestasjonen ved Glomfjord. Dette har trolig gitt løssnø i skogen og fokksnø på fjellet.

Det stor utbredelse av kantkorn ved bakken etter kuldeperiode i november og desember. Det meldes om hyppige drønn nord i regionen, mens det i sør er få faretegn.

Mountain weather

Wednesday 27. December 2023

25 mm precipitation, up to 60 mm in the most exposed areas. Rain up to 100 m a.s.l Wednesday night. Strong breeze from northwest. -10 °C to -4 °C at 1100 m a.s.l. Cloudy.

Thursday 28. December 2023

2 mm precipitation, up to 10 mm in the most exposed areas. Rain up to 100 m a.s.l Thursday night. Breeze from southeast. -18 °C to -5 °C at 1100 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

Du kan lett løse ut skred der nysnø og vind har gitt ferske fokksnøflak.
Fokksnøen har lagt seg over et ustabilt snødekke med vedvarende svake lag av kantkorn. Det kan derfor forbli lett å løse ut skred, og skred som løsner kan bli store. Kantkornlaget har trolig størst utbredelse nord i regionen.
