Avalanche warning for region Sør-Troms Monday 18.12.2023

Danger level 3 - Considerable avalanche danger

Published:
Be aware that there can be pockets with persistent weak layer beneath wind deposited snow. Be careful in these areas, especially in and close to terrain traps.
  • The danger is greatest until Monday before noon

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)

Sunday 17. December 2023

Snødekket er generelt tynt. På lørdag har mildvær med regn fuktet øvre deler av snødekket opp til ca 300-500 moh.

I høyereliggende områder, hvor nedbøren falt som snø på lørdag, er de svake lagene av kantkorn fortsatt intakte. I leformasjoner finner vi fokksnøflak som ligger på toppen av disse svake lagene.

Mountain weather

Sunday 17. December 2023

15 mm precipitation, up to 25 mm in the most exposed areas. Rain up to 400 m a.s.l during the afternoon. Moderate gale from southwest, changing to strong breeze from the west during the afternoon. -4 °C to 0 °C at 700 m a.s.l. Cloudy.

Monday 18. December 2023

7-9 mm precipitation. Rain up to 400 m a.s.l during the evening. Breeze from southwest. -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

Nysnø og vind har dannet fokksnøflak over et svakt snødekke i helgen. I høyden vil disse flakene fortsatt være svært lette å løse ut, og fjernutløsning kan også forekomme. Gi snøen tid til å stabilisere seg. Enkelte naturlig utløste skred kan ikke utelukkes.

I lavereliggende områder vil stabiliseringen går fortere og faren for å løse ut skred vil være mindre.
