Avalanche warning for region Hardanger Friday 17.02.2023

Danger level 3 - Considerable avalanche danger

Published:
The wind picks up and the precipitation increases. Demanding conditions. Be careful in lee areas with wind deposited snow, typically behind ridges, ribs and in gullies. Naturally released avalanches are possible in the alpine.
  • The danger is greatest from Friday before noon

Avalanche problems

Wind drifted 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

Wet snow (loose snow avalanches)

You can easily trigger avalanches on some steep slopes. Avalanches can get large enough to bury or even kill you (size 2).

Loose snow

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)

Thursday 16. February 2023

Heile snøpakka er smelteomdanna opp til om lag 900 moh. Vidare opp til 1200-1400 moh er snøoverflata våt, fuktig eller gjenfrose til skare. Høgt til fjells kan ein finne nokre cm med nysnø.

Ein kan òg, høgt til fjells, framleis finne lagdeling med restar av kantkorn ved bakken. Slike lag ligg godt beskytta under berande skarelag.

Torsdag morgon hadde temperaturen sokke til -3 °C ved Folgefonna skisenter (1212 moh) i Bykle. Det blas 6 m/s frå sørvest.

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

Mykje nedbør og aukande vind utover fredag gir krevjande snøforhold i fjellet. Vinden vil flytte laussnø inn ulike leområde når vinden dreier. Skred kan losne både naturleg og under vekta av ein skiløpar. Der temperaturen varierer rundt 0 °C, vil snøen stabilisere seg raskt. Eventuelle skred vil vere små. I høgfjellet kan større flak bli ustabile og skreda desto større.

Under mildvêrsgrensa vil våte skred vere problemet tidleg på dagen. Det gamle snødekket er ventes å drenere smeltevatn godt. Ein skiløpar kan likevel løyse ut våte laussnøskred i svært bratt terreng.
