Avalanche warning for region Vest-Telemark Monday 26.12.2022

Danger level 3 - Considerable avalanche danger

Published:
Complicated situation with persistent weak layers in the snow pack, wind and fresh snow.

Avalanche problems

Wind drifted snow (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).

Buried weak layer of new 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).

Buried weak layer of faceted snow above a crust

Wet snow (loose snow avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

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

Snøoverflaten består av vindpåvirket snø med ulike hardhet. På skjermede steder finnes lommer med upåvirket tørr snø. I skogen er snøen generelt ubundet.

Det finnes kantkorn og nedsnødd rim i snødekket. Det har vært observert drønn i løpet av sist uke. Dette kommer antakelig fra kollaps i vedvarende svake lag.

Fredag ble det meldt om noen drønn i snøen og rim på hardt underlag i Vinje.

Mountain weather

Sunday 25. December 2022

10 mm precipitation, up to 15 mm in the most exposed areas. Rain up to 800 m a.s.l during the evening. Fresh breeze from southeast, changing to strong breeze from the southeast during renoon. -15 °C to -6 °C at 1100 m a.s.l. Cloudy.

Monday 26. December 2022

10 mm precipitation, up to 15 mm in the most exposed areas. Rain up to 900 m a.s.l during renoon. Fresh breeze from southeast, changing to strong breeze from the west during the afternoon. -7 °C to 0 °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

Snø og vind vil danne ferske fokksnøflak i hovedsaklig nordvestlige heng. Om ettermiddagen kan vinddreining føre til at det også dannes noen ferske flak i nordøstlige heng. Ferske fokksnøflak kan være lette å løse ut - spesielt hvis de legger seg på rim dannet i kulda tidligere i uka. Merk også at det kan være mulig å påvirke svake lag med kantkorn nede i snødekket.
Faren for våte løssnøskred i lavereliggende områder er størst midt på dagen og minker når temperaturen synker utover ettermiddagen.
