Avalanche warning for region Heiane Thursday 10.12.2020

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 easily 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)

Wednesday 9. December 2020

De siste dagene har det kommet nedbør sammen med vind fra østlig retning. Vest- og nordvendte leområder har godt med snø, men snødekket er ellers generelt tynt. Det finnes oppstikkende steiner og vegetasjon i vindutsatt terreng. Snøgrensa har blitt lavere og sørøst i regionen er det skiføre fra ca. 600 moh.

Det er stor forskjell i snømengdene i regionen. I Hunnedalen i Sirdalsheiene er det ikke sammenhengende skiføre under 1000 moh onsdag.

Mountain weather

Wednesday 9. December 2020

3-5 mm precipitation. Fresh breeze from east, changing to moderate gale from the east during the evening. -4 °C to -1 °C at 1100 m a.s.l. Partly cloudy.

Thursday 10. December 2020

4 mm precipitation, up to 15 mm in the most exposed areas. Moderate gale from east. -5 °C to -2 °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

Nysnø og ny vindøkning gjør at skredproblemet får større utbredelse torsdag. I leheng kan vekta fra èn skiløper være nok til å løse ut middels store skred (str. 2). Skredfaren er størst over skoggrensa i Valleheiane og Bykleheiane.
