Avalanche warning for region Vest-Telemark Wednesday 10.03.2021

Danger level 2 - Moderate avalanche danger

Published:
Locally unstable conditions. A skier or a snow mobile may trigger avalanches in the fresh wind slabs, while persistent weak layers deeper in the snow in general is hard to trigger.

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 a car or destroy a small house (size 3).

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)

Tuesday 9. March 2021

I helgen har det blitt dannet enkelte flak med fokksnø, særlig i høyden. Der det ikke ligger fokksnø består snøoverflaten stort sett av skare. Under 1000 moh har snødekket tidligere vært gjennomfuktet.

I høyfjellet over ca. 1200 moh finnes det vedvarende svakt lag med kantkorn i snødekket, men dette ligger stort sett under hard skare.

Det har gått noen glideskred i sør/sørvende heng pga solpåvirkning den siste uka.

Mountain weather

Tuesday 9. March 2021

No precipitation. Fresh breeze from northwest, changing to breeze from the south during renoon. -10 °C to -1 °C at 1100 m a.s.l. Clear skies.

Wednesday 10. March 2021

8 mm precipitation, up to 15 mm in the most exposed areas. Fresh breeze from southeast, changing to moderate gale from the southeast during renoon. -9 °C to -5 °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

Økende vind og påfyll av snø vil danne ferske fokksnøflak hovedsaklig i nordvestvendte heng. Disse kan lett løses ut av en enkelt skiløper. Stedvis kan fokksnøen legge seg oppå glatt skare. I høyfjellet er det fortsatt mulig å løse ut skred på vedvarende svakt lag av kantkorn.
