Avalanche Danger Assessment

1 Low Over 4-500moh er det fuktig finkornet snø på overflaten. Ca 20-30cm i snitt, men den ligger ujevnt fordelt etter å ha blitt flyttet av vinden og er generelt fast (1F). Fant ingen lagdeling i denne snøen på dagens tur opp til ca 750 MOH, og den er godt bundet til underliggende grovkornet snø. Ikke mye vann i denne finkorna snøen i dag, men i formiddag var det litt sol og rundt bart berg løsnet det en del våte løssnøskred. Vil anslå FG1 på dagens tur, men pga av høye fjell i området kan nok fokksnø-problem være reelt høyt til fjells og forsvare FG2. Meldt varmere til helga, så da blir det nok enda mer våte løssnøskred. Kan kanskje hope seg opp med vann mellom finkornet snø og skare under. Forecast correct Tørrsnøproblemet går nok litt for lavt.

Avalanche Problems

Dry slab avalanche Buried weak layer of new snow Within half a meter Difficult to trigger 2 - Medium N, NE, E, SE, S above 1000 masl Har ikke vært over 750moh, men vil tippa at over ca 1000m finnes det fokksnø-problem.

Loose wet avalanche Loose snow Easy to trigger 1 - Small N, NE, E, SE, S, SW, W, NW between 1000 masl and 100 masl Mulig for skiløper å løse ut små våte løssnøskred under ca 400moh. Over 400m er det fuktig finkornet snø som løsner naturlig ved berg i bratt terreng.

Snow Cover

No snowdrift Elevation of new snow 400 masl. Snow line at 100 masl Under 400m: Våt, grovkornet snø. Synker ca 10cm ned med ski. Over ca 400m: Bærende skare med litt fuktig nysnø oppå.

Avalanche Activity

16. May. During the day Loose wet avalanche Numerous (10 or more). 1 - Small. Spontaneous release Widespread steep slopes. N, NE, E, SE, S, SW, W, NW. Between 1000 masl and 500 masl Ikke sett flakskred. Men mange små løssnøskred.
