[4] Over the next few days the system gradually developed further as it affected Tuvalu, before it was declared to be a tropical cyclone and named Joni by the Fiji Meteorological Service (FMS) during December 7.

Over the next couple of days the system intensified further as it was steered south-westwards and posed a threat to the Fijian dependency of Rotuma and the French territory of Wallis and Futuna.

The main impacts of Joni in Fiji were confined to the Western Division, with the islands of Yasawa, Mamanuca, Viti Levu, Kadavu and Vatulele being the worst affected areas.

On December 23, TCWC Nadi started to monitor a tropical depression, that had developed within the monsoon trough about 340 km (210 mi) to the northeast of Honiara on the Solomon Island of Guadalcanal.

[6][7] Later that day TCWC Nadi reported that Kina had peaked as a category 3 severe tropical cyclone with 10 – minute sustained wind speeds of 150 km/h (90 mph).

[11][12] A shallow tropical depression developed during February 3, within the South Pacific Convergence Zone about 170 km (105 mi) to the north-west of American Samoa.

[13] Later that day the NPMOC initiated advisories on the system and designated it as Tropical Cyclone 17P, while it was located about 520 km (325 mi) to the northeast of Nukuʻalofa.

[7][14] The system subsequently passed through the islands of central Tonga and was named Mick by the FMS during February 6, after it had developed into a Category 1 tropical cyclone.

[7][14] As Mick continued to move south-westwards further development was suppressed, by cooler waters and vertical wind shear as it accelerated through Fiji's Lau Islands.

[13][15] Mick's extratropical remnants were subsequently last noted during February 11, as they passed about 250 km (155 mi) to the northwest of Gisborne on New Zealand's east coast.

[16] Over the next couple of days, the system remained near stationary, before it started to move south-eastwards towards Palmerston in the Southern Cook Islands during February 12.

[7][16] During the next day, the FMS reported that the depression had developed into a Category 1 tropical cyclone and named it Nisha, before it passed near Palmerston, as it started to curve towards the east-southeast.
