Avalanche warning for region Heiane Saturday 05.12.2020

Danger level 2 - Moderate avalanche danger

Published:
Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Especially where the wind deposited slabs are thin or soft, a slab avalanche is easier to trigger here.

Avalanche problems

Wind drifted snow (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)

Friday 4. December 2020

Det har snødd jevnt utover torsdag og fredag. Mest snø har kommet i høyereliggende områder i Sirdalsheiane, Kvinesdal og Valleheiane. Østlig og sørøstlig vind opp mot kuling styrke har flyttet nysnøen inn i vest- og nordvestvendte heng. Snødekket er fremdeles generelt tynt med oppstikkende steiner i utsatt vindretning. I leheng er snødekket betydelig tykkere. Sparsomt skiføre. Nysnøgrensen ligger på 400 moh. men man må opp på 700 moh. før man får noen såle.

Ved Sirdal målestasjon (560 moh) ble det natt til fredag registrert 16 cm nysnø.

Mountain weather

Friday 4. December 2020

5 mm precipitation, up to 15 mm in the most exposed areas. Moderate gale from east. -7 °C to -3 °C at 1100 m a.s.l. Cloudy.

Saturday 5. December 2020

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 fortsatt forhold for ferske fokksnøflak i vest- og nordvestvendte heng i høyfjellet. Fokksnøen kan danne middels store skred. Svak temperaturstigning og minkende vind gjør at fokksnøflakene begynner å stabiliseres og skredfaren synker gradvis.
