Avalanche warning for region Helgeland Monday 26.12.2022

Danger level 2 - Moderate avalanche danger

Published:
Heavy snow drift is expected. Small wind slabs can be triggered. Large avalanches could fail on the old persistent layer of facets.
  • The danger is greatest from Monday evening

Avalanche problems

Persistent weak layer (slab avalanches)

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

Buried weak layer of surface hoar

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).

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)

Sunday 25. December 2022

Dagene før jul har det vært kraftig bygevær i regionen. Dette har ført til lokalt store mengder snø og vind i fjellet.

Lokalt kan det fortsatt ligge igjen svake lag av overflaterim i snødekket fra midten av desember. På fjellet i indre strøk det være svake lag av kantkorn fra kuldeperioden i november.

Mountain weather

Sunday 25. December 2022

4-6 mm precipitation. Precipitation as snow. Fresh breeze from southwest, changing to moderate gale from the southeast during the afternoon. -15 °C to -7 °C at 1100 m a.s.l. Partly cloudy.

Monday 26. December 2022

Little to no precipitation. Strong breeze from southeast, changing to moderate gale from the southeast during the afternoon. -11 °C to -4 °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

Skredfaren er økende i områder med stor snøtransport. Kraftig vind fra øst kan flytte store mengder snø i leheng og vil danne ustabile fokksnøflak.

Fokksnøen ligger på løsere lag av nysnø og/eller gamle svake lag av kantkorn eller overflaterim. Det kan være lett å påvirkelig disse lagene enkelte steder.

I ytre strøk kan økende temperaturer over null svekke snøoverflaten.
