Avalanche warning for region Vest-Telemark Saturday 06.02.2021

Danger level 2 - Moderate avalanche danger

Published:
There is a persistent weak layer buried in the snow pack. Use caution where the snow pack is thin or soft, and in steep terrain with fresh wind deposited snow.

Avalanche problems

Persistent weak layer (slab avalanches)

You can trigger avalanches on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Buried weak layer of faceted snow above a crust

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on a few 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)

Friday 5. February 2021

Snøoverflaten i høyden består nå stort sett av fokksnøflak av varierende hardhet. I skogen og skjermede formasjoner finnes løs snø og myke flak.

Rim observert i overflaten før helgen kan ha føyket ned enkelte plasser. Det finnes vedvarende svake lag med kantkorn under fokksnø i den gamle snøpakken. Disse lagene ligger nå under hard fokksnø og er vanskelige å påvirke.

Det ble rapportert om vindtransport i Rauland torsdag. Overflaterim er observert mange steder.

Mountain weather

Friday 5. February 2021

No precipitation. Fresh breeze from east. -21 °C to -13 °C at 1100 m a.s.l. Partly cloudy.

Saturday 6. February 2021

No precipitation. Fresh breeze from east. -21 °C to -14 °C at 1100 m a.s.l. Clear skies.

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 er mulig å løse ut store skred i et vedvarende svakt lag av kantkorn dypt i snødekket, men det skal stor tilleggsbelastning til. Vær forsiktig der snødekket er tynt og/eller mykt.

På vindutsatte områder kan det dannes små ferske fokksnøflak som er lett å løse ut. Stedvis kan overflaterim ha føyket ned, men det er stor usikkerhet knyttet til dette.
