Avalanche warning for region Vest-Telemark Friday 13.12.2019

Danger level 2 - Moderate avalanche danger

Published:
Be careful in areas with windslabs. A persistent weak layer of facets may be triggered, especially where the snow cover is thin.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on some 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)

Thursday 12. December 2019

De siste dagene har det kommet nysnø med vind fra S-V. Snødekket er i varierende grad vindpåvirket og ujevnt fordelt. På vindutsatte steder er det avblåst ned til skarelag, men fokksnøflak finnes i leområder. Under tregrensen en det mye løs snø.

Det er tidligere gjort observasjoner på kantkorn og begerkrystaller ved bakken, men det virker vanskelig å utløse skred i disse.

Onsdag ble noen små tørre flakskred naturlig utløst ved Haukeli.

Onsdag ble det observert sterk snøfokk øst på Hardangervidda.

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

Vind og nysnø vil danne ferske fokksnøflak i lesider. Det ligger et vedvarende svakt lag med kantkorn ved bakken som det enkelte steder kan være mulig å påvirke og løse ut skred på. Vær varsom der det ligger ferske fokksnøflak og der snødekket er mykt/tynt.
