their final warning because Yasi had degenerated into an extratropical cyclone. MetService monitored Yasi's remnants for another day, before the system dissipated about 1520 km (940 mi) to the south of Papeete, French Polynesia. Although no major damage was reported from any of the islands affected some minor damage was reported in Tonga, after Yasi caused heavy rainfall there. Tropical Cyclone Zaka On March 9, the FMS started to monitor a tropical depression had developed within an active convergence zone, about 150 km (95 mi) to the northwest of Noumea, New Caledonia. During that day an upper level trough moved over New Zealand which brought the jet stream over New Caledonia. As a result, this made the depression hard to locate with satellite imagery. However, later that day despite the system being poorly organized, the FMS reported that the depression had intensified into a tropical cyclone and named it Zaka. As they named it RSMC Nadi reported that the system had reached its peak 10-minute sustained windspeeds of 65 km/h (40 mph) with further development of the system restricted by strong vertical wind shear. Early on March 10, the JTWC designated Zaka as Tropical Cyclone 20P, while it had its peak 1-minute windspeeds of 75 km/h (45 mph). The FMS then issued their final advisory at 0600 UTC, as Zaka had weakened into a tropical depression and was moving into TCWC Wellingtons area of responsibility. TCWC Wellington and the JTWC monitored Zaka for another day before it was last noted during March 11 as it became an extratropical cyclone. Zaka dumped of rain on Vanuatu in just 24 hours. Tropical Cyclone Atu On March 4, the JTWC started to monitor an area of disturbed weather that had developed within the Australian region about , to the southeast of Port Moresby in Papua New Guinea. Over the next few days, the system remained weak and gradually moved southeast before it crossed 160°E and moved into the basin on March 9. During the next day, both the JTWC and the FMS started to monitor the system as a tropical depression as it moved through the Loyalty Islands. On March 11, the depression intensified into a tropical cyclone as it moved southeastward, prompting the FMS to name it Atu at 1800 UTC. Early on March 12, the JTWC reported that Atu had reached its peak 1-minute windspeeds of 100 km/h (65 mph). Later
