Avalanche Danger Assessment

1 Low Det ligger eldre fokksnøflak over vedvarende svake lag, men generelt skal det svært mye til for å påvirke disse, og det er kun i få områder skredproblemet finnes. Som skiløper kan det være disse områdene det er mest interessant å oppsøke, og man bør være oppmerksom på hvor hard fokksnøen er. Der det er myke/tynne fokksnøflak vil det være lettere å løse ut skred. Forecast correct
