Unstable wind slabs may cover a persistent weak layer in lee areas. Avalanches can be triggered by a single skier.
  • The danger is greatest from Sunday afternoon

Avalanche problems

Persistent weak layer (slab avalanches)

You can very easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2). 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)

Saturday 4. February 2023

Det har vært rolig vær med lite nedbør de siste dagene. Det ligger mye løs snø i terrenget. Under den løse snøen ligger det en kompakt snødekke bestående av skare og smelteformer.

Det har dannet seg et svakt lag av kantkorn i nysnøen og det er rim på snøoverflaten. Det er også ustabile lag ved bakken som er vanskelig å påvirke, men kan gi drønn der snødekket er tynt.

Det har blåst stiv kuling (15 m/s) på Kistefjellet (980 moh) ved Finnsnes natt til lørdag.

Mountain weather

Saturday 4. February 2023

2-6 mm precipitation. Precipitation as snow. Strong breeze from southwest, changing to fresh breeze from the south during the afternoon. -12 °C to -2 °C at 700 m a.s.l. Cloudy.

Sunday 5. February 2023

6-10 mm precipitation. Rain up to 300 m a.s.l Sunday night. Strong breeze from south, changing to strong breeze from the west during the afternoon. -6 °C to 0 °C at 700 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 ventes å øke når vind og nysnø danner ferske ustabile fokksnøflak. Når vinden dreier mot vest utover dagen kan flere heng bli ustabile.
Stedvis kan det ligge ustabile lag av rim eller kantkornet snø under fokksnøen. Her kan det være svært lett for en skiløper å løse ut skred. Mindre skred kan også løses ut i den ferske fokksnøen.
