Avalanche warning for region Vest-Telemark Sunday 23.12.2018

Danger level 1 - Low avalanche danger

Published:
Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. A persistent weak layer can be present underneath fresh wind deposited snow in isolated features.

Avalanche problems

Wind drifted snow (slab avalanches)

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

Poor bonding between layers in wind deposited snow

Persistent weak layer (slab avalanches)

You can trigger avalanches on a few 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)

Saturday 22. December 2018

Snøoverflaten er i varierende grad vindpåvirket og fokksnøen veksler mellom harde og myke flak. Mest fokksnø ligger i N og V fjellsider. Stedvis finnes det også løssnø som kan transporteres. I skogen er snøen i mindre grad vindpåvirket. Det er fortsatt mindre snø enn normalt for årstiden.

Observasjoner fra torsdag denne uka sier at det finnes nedsnødd rim eller skare nede i snødekket, men utbredelsen er usikker.

Tidligere i uka ble det observert skytende sprekker i overflaten i Rauland.

Mountain weather

Saturday 22. December 2018

Little to no precipitation. Breeze from east. -13 °C to -8 °C at 1400 m a.s.l. Partly cloudy.

Sunday 23. December 2018

No precipitation. Fresh breeze from northwest. -15 °C to -7 °C at 1400 m a.s.l. Partly 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 kan være mulig å finne enkelte ustabile fokksnøflak over svake lag med nedføyket rim, men utbredelsen ventes å være liten. Faregraden vil derfor fortsatt holdes lav.
Husk at mange steder har lite snø og mye oppstikkende stein. Selv små skred kan gjøre stor skade.
