No precipitation 2 m/s Nydelig vær i dag, lite vind. Men fjellet er påvirket med mye vær de siste dagene, regn-snø-ekstremt mye vind

Hard skare oppå snø. Hvis denne skara blir snødd ned, kan det bli et svakt lag

Danger Sign

Recent snowdrift Område: Generelt på fjellet. Beskrivelse: Søn/regn med mye vind de siste dagene

Tests

ECTX Good ECT 29 Testen ble tatt der vi fant mest snø, ca 30grader. Ingen sprekkdanning. Fant en skliflate, ca 40cm under, men dårlig binding. Men tenkelig at hvos bratt nok, kan dette gå, og kan bli stort.
