Avalanche warning for region Heiane Sunday 24.01.2021

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).

Buried weak layer of new 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)

Saturday 23. January 2021

Snødekket er variert etter mykje snø og vind tidlegare i veka. I høgda er det tørr fokksnø som no er hovudsakleg fast, men det er også mjukare parti i skjerma områder. Lågare i fjellet er det skare opp til det som var mildværsgrensa under det store snøværet.

Det er tidlegare observert svake kantkornlag i snødekket fleire stader i regionen. Det er uklart korleis dei svake laga vil arte seg no når det har lagt seg store mengder snø på det eldre snødekket.

Fredag er det observert flere str 2 og 3 skred i Hunnedalen.

Mountain weather

Saturday 23. January 2021

6 mm precipitation, up to 16 mm in the most exposed areas. Strong breeze from southwest, changing to fresh breeze from the southwest during the afternoon. -6 °C to -3 °C at 1100 m a.s.l. Cloudy.

Sunday 24. January 2021

Little to no precipitation. Breeze from southeast. -9 °C to -5 °C at 1100 m a.s.l. Partly 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

Fokksnøflak frå sist store snøfall ligg til stabilisering i høgda. Dette tek tid, så det kan være mulig å påvirke slike flak for ein skiløpar, spesielt der fokksnøen er mjuk eller tynn. Eldre snødekke inneheld svake lag av kantkorn, men det skal truleg mykje til at skiløpar kan påvirke desse.
