Avalanche warning for region Indre Sogn Wednesday 23.02.2022

Danger level 3 - Considerable avalanche danger

Published:
Conditions are challenging. Be sure you have enough knowledge and experience before travelling in steep terrain. Be extra careful in lee areas with wind deposited snow. There are still weak layers in the snowpack.

Avalanche problems

New snow (slab avalanches)

Avalanches may release spontaneously on some steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3).

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

Avalanches may release spontaneously on a few steep slopes. Avalanches can get large enough to bury a large truck or destroy several houses (size 4). Remote triggering is possible.

Buried weak layer of faceted snow beneath a crust

Wet snow (loose snow avalanches)

Avalanches may release spontaneously 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)

Tuesday 22. February 2022

Snøoverflaten preges av tørr løssnø i skjerma områder. Over skogen er snødekket vindpåvirket i varierende grad. Det har vært mye fint skiføre den siste tiden. Under den nyeste snøen finnes et tynt skarelag opp til ca 750 moh. Gjennom vinteren har mye vind fra vest flyttet mye snø over i østvendt terreng.

16.feb ble det observert kantkorn under tynn mildværsskare fra januar på 1000 moh på et sted med tynt snødekke. Skarelaget med kant finnes opp til ca.1300 moh, og er hovedsakelig et problem i områder med tynt snødekke.

Fredag ble det meldt om et middels stort skiløperutløst skred i Sogndalsdalen, og flere glideskred i Jostedalen.

Mountain weather

Tuesday 22. February 2022

7 mm precipitation, up to 12 mm in the most exposed areas. Precipitation as snow. Fresh breeze from southeast. -19 °C to -5 °C at 1400 m a.s.l. Partly cloudy.

Wednesday 23. February 2022

30 mm precipitation, up to 45 mm in the most exposed areas. Rain up to 700 m a.s.l during the afternoon. Gale from southwest. -8 °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

Kraftig vind fra sørvest og mye nysnø vil gi store ustabile fokksnøflak i leheng. Store naturlig utløste skred kan forekomme.

Enkelte steder kan det ha utviklet seg et vedvarende svake lag rundt et gammelt skarelag i høyden. Laget kan føre til at skred kan få stor bruddforplanting.

Under mildværsgrensen forventes naturlig utøste våte løssnøskred.
