Yasi brought significant rain to both Fiji and Tonga before it dissipated on January 19 to the south of Papette in French Polynesia. After Yasi dissipated, no tropical cyclones were recorded in the basin until March 9; however on February 12, a tropical low developed to the west of New Caledonia. Over the next 24 hours the low deepened to about 1002 hPa before it crossed 160°E and moved into the Australian region where it became known as the Queen Elizabeth II storm. On February 22 and 23, a shallow tropical depression moved around the Fijian archipelago and caused some flooding of low-lying areas in Vanua Levu. On March 9 and 10, Tropical Cyclones Zaka and Atu both developed near New Caledonia, about apart and took similar tracks towards the southeast before becoming extratropical. On March 21, the final tropical cyclone of the season developed to the northeast of Vanuatu. Over the next couple of days the depression gradually developed further and was named as Beti, before it passed over Vanuatu and New Caledonia. On March 29, after it had passed over New Caledonia, Beti degenerated into an extratropical cyclone, before dissipating on April 2. After the season ended the name Beti was retired from the tropical cyclone naming lists.

During the following day, the depression rapidly developed further as it interacted with the South Pacific Convergence Zone, before the NPMOC initiated warnings on the system and designated it as 08P. At 0000 UTC on January 17, the NPMOC reported that the depression had reached its peak 1-minute sustained windspeeds of 85 km/h (50 mph), while the FMS reported that the depression had intensified into a tropical cyclone while it was located about 510 km (320 mi) to the southeast of Nukualofa, Tonga.
