Avalanche Danger Assessment

2 Moderate Generelt stabilt der jeg beveget meg. Men det kan være ustabil fokksnø i leområder mot øst. Det kan og være områder høyt i fjellet der man kan løse ut skred i gamle kantkornlag dypt i snødekket Relativt liten endring i skyggesider da været er kjølig. I solsider omvandles snøen fortere pga solinnstråling

Avalanche Problems

Dry slab avalanche Buried weak layer of new snow The overlying slab is soft. Easy to trigger 2 - Medium NE, E, SE, S above 500 masl
