Avalanche warning for region Indre Sogn Saturday 18.02.2023

Danger level 3 - Considerable avalanche danger

Published:
Unstable wind slabs may cover a persistent weak layer in lee areas. Avalaches can be triggered by a single skier.

Avalanche problems

Persistent weak layer (slab avalanches)

You can easily trigger avalanches on some 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 beneath a crust

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on some 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)

Friday 17. February 2023

Fredag snør det og det legg seg nysnø i overflata.

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 under eit skarelag, har det utvikla seg eit anna kantkornlag. Dette gjeld også frå ca 1100-1200 moh og oppover.

Måndag vart det observert nokre glideskred i Jostedal.

Fredag ettermiddag snør det ned til 200 moh i Jostedal.

Mountain weather

Friday 17. February 2023

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

Veret held fram med sterk vind og påfyll av nysnø. Vinden blåser snøen inn i leområder og dannar fersk fokksnø som du lett kan løyse ut skred i.
Observasjonar tyder på at det kan ha blitt danna eit svakt lag av kantkorn høgt i snødekket som denne snøen legg seg på, men det er usikkerheit rundt eigenskapane til dette laget.

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