Avalanche Danger Assessment

1 Low Generelt stabile forhold. Gjelder å følge med på nattetemperatur og starte tidlig for å få kurant skiføre i denne delen av regionen nå. Glideskred kan forekomme Nedbør utover helga vil drenere godt i denne snøen og eventuell nysnø er fuktig og legger seg på gunstig vis mot varm snø. Forecast correct
