Avalanche warning for region Indre Sogn Wednesday 15.12.2021

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 persistent 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)

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

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 14. December 2021

Snøoverflaten består av fokksnøflak med ulik hardhet i mange himmelretninger. Sannsynligvis størst utbredelse mot vest og nord. På vindutsatte steder er overflaten hard fokksnø, is eller bart fjell. Det er mest snø vest i regionen.

Det finnes vedvarende svakt med nedsnødd små kantkorn rundt skarelag nede i snødekket som ble dannet under kuldeperioden i november. Sist helg var det et par observasjoner på drønn i snødekket som indikerer at disse er mulig å påvirke.

Observasjon fra ca 1000moh i Sogndalsdalen på søndag sier snødybde på 75 cm, men det varierer i terrenget.

Mountain weather

Tuesday 14. December 2021

18 mm precipitation, up to 30 mm in the most exposed areas. Rain up to 1100 m a.s.l during the evening. Fresh breeze from southwest, changing to gale from the southwest during renoon. -7 °C to -1 °C at 1400 m a.s.l. Cloudy.

Wednesday 15. December 2021

22 mm precipitation, up to 50 mm in the most exposed areas. Rain up to 1100 m a.s.l Wednesday night. Fresh breeze from west, changing to moderate gale from the west during the evening. -5 °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

Nysnø og vind gir økt pålagring og ustabile fokksnøflak i fjellsider vendt mot nord og øst.
Der det gamle snødekket er tynt, kan det være mulig at vedvarende svakt lag blir påvirket og løsner. Skredene kan bli store. Det er mulig med naturlig utløste skred.

Under ca 1000moh vil mildvær og regn kunne svekke snødekket, særlig der snøen er utsatt for regn første gang.
