On February 3, the JTWC started to monitor a subtropical disturbance that had persisted about 815 km (505 mi) to the south-southeast of Nadi, Fiji, within an area that was marginally conducive to further development.[1] During that day, the system moved north-eastwards before it was classified as Tropical Disturbance 06F by the FMS, while it was located about 270 km (165 mi) to the southwest of Pago Pago in American Samoa.[2]
