Avalanche warning for region Voss Monday 14.12.2020

Danger level 2 - Moderate avalanche danger

Published:
Locally unstable conditions. A skier or a snow mobile may trigger avalanches in the fresh wind slabs, while persistent weak layers deeper in the snow in general is hard to trigger.

Avalanche problems

Wind drifted snow (slab avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches are relatively harmless to people, but can knock you off balance. Can be dangerous close to terrain traps. (size 1)

Buried weak layer of new snow

Persistent weak layer (slab avalanches)

You can trigger avalanches on a few 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)

Sunday 13. December 2020

Snøoverflaten er stort sett hard etter mye og kraftig vind den siste tiden. Det er mest sammenhengende snø i konkave formasjoner, ellers mye avblåst og bart.

Det er observert kantkornet snø over skarelag ved Mjølfjell og på Vikafjellet over 800-900 moh. Kantkorn finnes sannsynligvis der mildvær dannet skare for et par uker siden og i alle himmelretninger.

Fra Vikafjell ble det lørdag meldt om hard snøoverflate og lite snø tilgjengelig for vindtransport.

Mountain weather

Sunday 13. December 2020

No precipitation. Breeze from east, changing to fresh breeze from the southeast during the afternoon. -6 °C to -1 °C at 1100 m a.s.l. Cloudy.

Monday 14. December 2020

4 mm precipitation, up to 10 mm in the most exposed areas. Moderate gale from southeast, changing to fresh breeze from the southeast during the evening. -4 °C to -1 °C at 1100 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 og litt ny snø vil over tregrensen gi ferske fokksnøflak. En skiløper vil kunne løse ut små skred i noen heng eller middels store skred i utsatte terrengformasjoner. Mest utsatt er heng mot N-NV-V.
Det finnes også et vedvarende svakt lag av kantkorn dypere i snødekket. Skiløpere kan påvirke dette fra færre steder, men skred kan bli større, opp til str 3. Vær spesielt oppmerksom ved inngangen til eldre fokksnøflak. Hold tilstrekkelig avstand til skredterreng. Drønnelyder og sprekker i snødekket er tydelige faretegn som må tas på alvor.
