Avalanche warning for region Indre Sogn Sunday 19.12.2021

Danger level 2 - Moderate avalanche danger

Published:
Be careful of recently loaded storm slabs. 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).

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 18. December 2021

De siste dager har det vært mildvær høyt til fjells, og snøpakka er gjennomfuktet opp til 800-1200 moh. I høyder over dette ligger det noe våt nysnø.

Det har tidligere denne uka vært observert vedvarende svakt med nedsnødd kantkorn rundt skarelag nede i snødekket som ble dannet under kuldeperioden i november. Det er usikkert hvor godt mildværet de siste dagene har nøytralisert disse lagene.

Torsdag ble det observert drønn i snøen og skytende sprekker i Luster.

Mountain weather

Saturday 18. December 2021

2-5 mm precipitation. Rain up to 1600 m a.s.l Saturday night. Strong breeze from west. -4 °C to 1 °C at 1400 m a.s.l. Partly cloudy.

Sunday 19. December 2021

Little to no precipitation. Strong breeze from north. -9 °C to -3 °C at 1400 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

Det ventes overgang til kuldegrader i hele regionen, og snødekket vil fryse til og danne skarelag der det har vært fuktet tidligere i uka. På de høyeste toppene kan det ligge noen ustabile fokksnøflak. Utbredelsen av svake lag nedover i snøpakka er usikker nå etter mildværsperioden, men vær inntil videre oppmerksom der snødekket er tynt.
