Avalanche Activity

26. May. During the day No avalanche activity Har rast fra seg og ikke nok solinnstråling gjennom formiddagen til å skape aktivitet.

Weather

No precipitation 10 °C 4 m/s from SW ↗ 90% clouds Overskyet. Høyt skydekke. Varmt. Skyfritt i går.

Snow Cover

50 cm in total No snowdrift 0 cm new snow Snow line at 700 masl Wet loose snow Wet Sammenhengende skiføre i Hunnedalen fra om lag 700m sektor i nordvendt terreng. Sugende skiføre fra 1000m til dalbunn. Mye bart terreng i syd og vestvendt mens nord og øst fortsatt har bra med snø igjen.

Danger Sign

No signs observed Område: I dalen/fjorden

Avalanche Danger Assessment

1 Low Generelt stabile forhold. Våte skiløperutløste løssnøskred i bratt terreng er nok beste måten å få flyttet snø på i dag. Status quo i morgen før mer sol og høye temperaturer vil svekke bindingene fra torsdag av. Forecast correct FG2 må være forbeholdt høyereliggende strøk av regionen nå.

Notes

Dessverre ikke mulighet til å komme meg høyere til fjells grunnet lang reisevei og tidsnød.
