Avalanche warning for region Indre Sogn Sunday 07.03.2021

Danger level 2 - Moderate avalanche danger

Published:
Unstable wind slabs may cover a slippery crust,or 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 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 easily 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)

Saturday 6. March 2021

I fjellet kom det torsdag og fredag et lite dryss av nysnø på en hard snøoverflate. Dette har gitt små fokksnøflak på skaren. Under 1000 moh er snødekket smelteomvandlet. Over 1000 moh finnes fokksnøflak i overflaten. Mildvær de siste 2 ukene har tæret hardt på snøen i lavlandet.

Det finnes vedvarende svakt lag av kantkorn under skare høyt i snødekket.

Fredag ble det meldt om drønn i snødekket (kantkorn under skare) på tynt snødekke ved Vigdalen.
Lørdag formiddag ble det fra Jostedalen meldt om litt våt nysnø nede i dalen og moderat til kraftig snøfokk over tregrensen.

Mountain weather

Saturday 6. March 2021

10 mm precipitation, up to 20 mm in the most exposed areas. Gale from northwest. -10 °C to -2 °C at 1400 m a.s.l. Cloudy.

Sunday 7. March 2021

No precipitation. Strong breeze from northwest, changing to breeze from the north during the afternoon. -14 °C to -7 °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

Lørdagens fokksnøflak vil fortsatt være ustabile i noen heng, fortrinnsvis mot S-SØ-Ø. Her vil en skiløper kunne løse ut middels store skred.

I høyfjellet finnes vedvarende svake lag i snødekket som kan gi store skred.
Det er observert svakt lag av kantkorn under skare høyt i snødekket. Dette har gitt skredaktivitet i naboregionene Jotunheimen og Hallingdal.

Under tregrensen er snødekket stort sett stabilt.
