Avalanche warning for region Heiane Thursday 28.01.2021

Danger level 2 - Moderate avalanche danger

Published:
Be careful in areas with windslabs. A persistent weak layer of facets may be triggered, especially where the snow cover is thin.

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).

Poor bonding between layers in wind deposited 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)

Wednesday 27. January 2021

I fjellet er det fokksnø av ulik hardhet etter sist snøfall. I skogen og skjermede områder er det mykere vindtransportert snø og løssnø.

Det finnes kantkornlag i det eldre snødekket.

Skredaktiviteten har avtatt siden helgen.

Observasjon i Hunnedalen viser ikke noe kantkornproblem, så kantkornproblemet gjelder trolig ikke hele regionen.

Mountain weather

Wednesday 27. January 2021

Little to no precipitation. Breeze from northwest. -13 °C to -8 °C at 1100 m a.s.l. Partly cloudy.

Thursday 28. January 2021

No precipitation. Breeze from northwest. -12 °C to -6 °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

De eldre fokksnøflakene fra helgen stabiliseres gradvis og det forventes nå at det generelt skal stor belastning til for å løse skred i disse.
Det finnes vedvarende svake lag av kantkorn i det eldre snødekket, som kan løses ut der snødekket er tynt eller mykt. Skred i dette laget kan bli store.
