Avalanche warning for region Heiane Saturday 17.12.2022

Danger level 2 - Moderate avalanche danger

Published:
Use caution in steep terrain with fresh storm slabs. Persistant weak layers of facets or buried surface hoar may be present in the snow pack.

Avalanche problems

New 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)

Friday 16. December 2022

De siste dagene har det kommet 20-30 cm snø uten særlig vind. Snøen har de fleste steder lagt seg på bar bakke. Snødekket er generelt tynt og de fleste steder usammenhengende.
Fra tidligere snøfall og vind lå det små dyner/harde flak noen få plasser i høyfjellet, særlig i vestvendt skjermet terreng, bak rygger og i forsenkninger i terrenget.

Mountain weather

Friday 16. December 2022

6 mm precipitation, up to 12 mm in the most exposed areas. Rain up to 200 m a.s.l during the afternoon. Fresh breeze from south. -15 °C to -4 °C at 1100 m a.s.l. Cloudy.

Saturday 17. December 2022

25 mm precipitation, up to 40 mm in the most exposed areas. Rain up to 600 m a.s.l during the evening. Breeze from south, changing to strong breeze from the southwest during the evening. -8 °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 mye løs snø i terrenget kombinert med vind vil gi ustabile nysnøflak. Nysnøflakene kan ligge over svake lag med kantkorn og rim. Flakene er myke slik at du som skiløper påvirker dypere ned i snøen, og lett kan løse ut skred. Skred som løsner kan bli str 2.

I områdene som får mest nysnø kan naturlig utløste skred forekomme, dersom nysnøflak legger seg over svakt lag av kantkorn eller rim.
