Weather

No precipitation -1.6 °C 6 m/s 70% clouds Bygevær. Sol og fint innimellom her på fjellet, med 5-8 ms. Regn og trist nede på Voss i dag tidleg. Varmt i sola, rundt -1,5 grader her på 950 moh.

Snow Cover

Some snow drift Elevation of new snow 550 masl. Snow line at 500 masl Storm slab (soft slab) Dry Fersk fokksnø oppå smeltepakke. Var kald og tørr snø i dag tidleg, men merkar det blir fuktig snø no når sola kjem. Veldig fint skiføre i nord/østlig sektor. Begynner å sjå ut som ein normal vinter med tanke på snømengde i terrenget her på Vikafjellet. Til dels store skavler mot nord og øst her i høgfjellet.

Avalanche Danger Assessment

2 Moderate Fokksnøen stab. Seg raskt pga gunstige temperaturer. Har ikkje sett noko ferske skred eller skavlbrudd Sola tar skikkelig no, kan bli våte løssnøskred i solsida utover dagen om det blir skyfritt. Meldt meir nedbør og sterk vind neste dagane, spesielt på mandag. Det ligg ein god del snø jevnt over på fjellet som kjem til å bli flytta på. Forecast correct
