Avalanche warning for region Indre Sogn Wednesday 15.02.2023

Danger level 2 - Moderate avalanche danger

Published:
Locally unstable conditions. A skier or a snow mobile may trigger avalanches in the fresh wind slabs, while persistent weak layers deeper in the snow in general is hard to trigger.
  • The danger is greatest from Wednesday afternoon

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on a few 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)

Tuesday 14. February 2023

Snøoverflata er smelteomdanna opp til ca 1100 moh. I Høgfjellet er det vindpakka mjuk snø.

I høgfjellet over 1100-1200 moh viser tidlegare observasjonar at kantkornlaget ved bakken framleis er intakt, men det ligg no under hard og berande snø.
Høgare i snøen over eit skarelag, har det også utvikla seg eit kantkornlag. Dette er også frå ca 1100-1200 moh og oppover.

Måndag vart det observert nokre glideskred i Jostedal. Det har gått eit svært stort skred ved Styggevatn i Jostedal, mest truleg då det var sterk vind torsdag sist veke.

Mountain weather

Tuesday 14. February 2023

Little to no precipitation. Breeze from west. -12 °C to 0 °C at 1400 m a.s.l. Partly cloudy.

Wednesday 15. February 2023

2-4 mm precipitation. Rain up to 1500 m a.s.l during the afternoon. Breeze from south, changing to strong breeze from the south during the afternoon. -6 °C to 1 °C at 1400 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

Sterk vind om ettermiddagen kan gjere at det bles snø inn i leheng og dannar ferske fokksnøflak. Kor stort omfanget av dette vert er avhenigig av kor mykje laussnø som finst tilgjengeleg for vindtransport.

I høgfjellet finst det kantkorn ved bakken, men dette ligg under hard og bærande snø og er vanskeleg å påverke.
