Snow Cover

120 cm in total Some snow drift 0 cm new snow Elevation of new snow 0 masl. Snow line at 0 masl. Layered snow begins at 550 masl Storm slab (soft slab) Dry over tregrensen er snødekket vindpakket mykt med en god del løs ubunden snø. under skoggrensen er snødekket fuktig men ikke vått. Begrenset påvirkning av solinnstråling på snødekket har ført til at det gamle snødekket fortsatt er stabilt og har opprettholdt gode bindinger.

Weather

No precipitation -0.1 °C 6 m/s from W → 90% clouds

Avalanche Danger Assessment

2 Moderate stabiliteten i det gamle snødekket er god. Stabiliteten i fersk fokksnø forventes å stedvis være middels god til dårlig. Det er ikke observert skredaktivitet på strekningen Sørreisa-Bardufoss i dag. Været neste døgn tilsier pålagring av fokksnø i flere eksposisjoner grunnet varierende vindretning, primært i NV-N-Ø-SØ eksposisjoner. Kraftig vind og tildels betydelige nedbørsmengder ifa snø i fjellet , samt en god del løs ubunden snø tilgjengelig for vindtransport, vil kunne øke skredfaren ila neste døgn. Forecast correct
