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

Weather

No precipitation -3 °C 4 m/s from E ← 35% clouds Pent,kjølig vind fra øst, slørskyer mot sør og vest

Snow Cover
