Avalanche warning for region Indre Sogn Saturday 18.12.2021

Danger level 2 - Moderate avalanche danger

Published:
Locally unstable avalanche conditions in the alpine. 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

Persistent weak layer (slab avalanches)

You can easily trigger avalanches on a few steep slopes. Avalanches can get large enough to bury a car or destroy a small house (size 3). Remote triggering is possible.

Buried weak layer of faceted snow near surface

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).

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)

Friday 17. 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 finnes vedvarende svakt med nedsnødd små kantkorn rundt skarelag nede i snødekket som ble dannet under kuldeperioden i november. Observasjon fra Luster tirsdag forteller om svakt lag med kantkorn under flak. Mildværet de siste dager har antakelig nøytralisert en del av disse lagene slik at de nå mest sannsynlig bare er å finne i de høyestliggende delene av regionen.

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

Mountain weather

Friday 17. December 2021

1 mm precipitation, up to 10 mm in the most exposed areas. Rain up to 1900 m a.s.l during the afternoon. Fresh breeze from west, changing to strong breeze from the west during the afternoon. -3 °C to 2 °C at 1400 m a.s.l. Partly cloudy.

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.

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

Mildvær vil gi regn høy til fjells, men snøgrensa vil gradvis krype nedover i løpet av dagen og det kan dannes noen ferske nysnøflak. Den synkende temperaturen vil også gjøre at overflaten kan fryse til flere steder og danne skarelag. Vær oppmerksom på muligheten for å påvirke vedvarende svake lag der snødekket er tynt.
