Avalanche warning for region Indre Fjordane 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 evening

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

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 700-900 moh. Vidare opp til er snøoverflata våt, fuktig eller gjenfrose til skare.
I dei høgaste fjellområda i indre delar av regionen, kan det i leområde ligge tørre flak av vindtransportert snø.

På Strynefjellet og i Sunnfjord er det observert kantkorn i over og under skarelag djupt i snøpakka. Desse kan utgjere eit skredproblem over 1200 moh.

På Trolledalalsegga (1020 moh) i Stad, var det torsdag ettermiddag -3 °C. Det blas 14 m/s frå sør.

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 herfra vil vere små. I høgfjellet kan større flak bli ustabile og skreda desto større.

Under mildværsgrensa kan ein skiløper lett løyse ut våte løssnøkred i svært bratt terreng.
