Avalanche warning for region Vest-Telemark Thursday 22.12.2022

Danger level 2 - Moderate avalanche danger

Published:
Wind deposited snow could rest on a persistent weak layer of facets. In some areas an avalanche can be triggered by snowmobiles

Avalanche problems

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).

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 21. December 2022

De siste dagene er det observert 20-40 cm nysnø vest i regionen, mindre nysnø lenger øst.
Det er fremdeles generelt lite snø i terrenget. Der vinden har fått tak kan det finnes lommer med vindpåvirket snø.

Snøprofiler har vist at det finnes kantkorn og nedsnødd rim i snødekket. Observerte drønn i løpet av sist uke skyldes nok kollaps i vedvarende svake lag.
Observasjon fra Valle lørdag på ca 1000moh indikerer at det kan være mulig å påvirke svakt lag nede i snødekket.

Mountain weather

Wednesday 21. December 2022

1 mm precipitation, up to 6 mm in the most exposed areas. Rain up to 500 m a.s.l Wednesday night. Breeze from southwest. -5 °C to -1 °C at 1100 m a.s.l. Cloudy.

Thursday 22. December 2022

7-10 mm precipitation. Rain up to 700 m a.s.l during the afternoon. Breeze from southwest, changing to breeze from the northwest during the evening. -8 °C to -1 °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

Det finnes ustabile flak med fokksnø. Disse kan løsne på svakt lag innad i fokksnøen. Vær oppmerksom der fokksnøen er myk og/eller tynn. Her er det lettere å påvirke svake lag med kantkorn/rim nede i snødekket.
