Avalanche Danger Assessment

1 Low Stabile og forutsigbare forhold. Temp, nedbør og sol styrer skredfaren. Vinteren er i ferd med å avvikles. Men det er i ferd med å bli godt skiføre med storkornet snø som drenerer godt.

Weather

No precipitation 0 °C 3 m/s from SE ↖ 30% clouds Litt kaldere enn tidligere dager. Bygevær tidligere i dag.

Snow Cover

No snowdrift 1 cm new snow Crust Dry Det minker jevnt og trutt. Ikke noe åpenbar ny skredaktivitet siste 3-4 dager. Større korn i den storkorna snøen nå. Tilfrosset snøoverflate fra 1300, bærende. Skiføret var bra i dag, bedre enn på lenge. Det er råttent rundt steiner og på tynt snødekke. Må over ca 1000 moh for å få sammenhengende skiføre.

Danger Sign

No signs observed
