|---|---|
| Peak intensity | 150 km/h (90 mph) (10-min); 955 hPa (mbar) |
Script error: No such module "Labelled list hatnote". On January 13, TCWC Nadi started to monitor a tropical depression that had developed, within a trough of low pressure near the island nation of Tuvalu.[6] Over the next few days the system gradually developed further before it was named Tusi during January 16, after it had become equivalent to a modern-day category 1 tropical cyclone on the Australian tropical cyclone intensity scale. After being named the system gradually intensified as it moved southeastwards along the trough, between the islands of Fakaofo and Swains during January 17. Tusi's eye subsequently passed near or over American Samoa's Manu'a Islands early the next day, as the system peaked in intensity with 10-minute sustained wind speeds of 150 km/h (95 mph). The system subsequently posed a threat to the Southern Cook Islands, however this threat gradually diminished as Tusi moved southwards and approached 25S on January 20.
Severe Tropical Cyclone Uma

Cyclone Uma caused severe damages in Vanuatu. The storm formed on February 4 and dissipated on February 10.
Tropical Cyclone Veli

Lua error in package.lua at line 80: module 'Module:InfoboxImage/data' not found. Lua error in package.lua at line 80: module 'Module:InfoboxImage/data' not found. | |
| Duration | February 7 – February 9 |
|---|---|
| Peak intensity | 85 km/h (50 mph) (10-min); 987 hPa (mbar) |
The precursor tropical low to Cyclone Veli formed within the Australian region on February 5, about 725 km (450 mi) to the south-east of Port Moresby in Papua New Guinea.[7] During the next day the low moved eastwards and gradually developed further, before it became equivalent to a category 1 tropical cyclone on the Australian scale, as it reached its 10-minute sustained wind speeds of 85 km/h (50 mph).[7] As the system continued to move eastwards it crossed 160°E and moved into the South Pacific basin during February 7, before the FMS named it Veli later that day on the basis of satellite derived evidence.[7][8] During that day the system continued to move eastwards, before as it passed near to Espiritu Santo, Veli started to move steadily towards the south-east.[8] Early the next day the JTWC initiated advisories and started to monitor Veli as Tropical Cyclone 16P, with peak 1-minute sustained windspeeds of 45 km/h (30 mph).[9][10] During that day strong upper level north-westerlies caused vertical windshear to increase over Cyclones Veli and Uma and thus weakened them.[8] During February 9, Cyclone Veli absorbed Uma and formed a complex low, which moved slowly south-eastwards and became extratropical.[8] Damage within Vanuatu was either minimal or went unreported, as the island nation was more concerned with the aftermath of Cyclone Uma.[11]

A shallow tropical depression developed within a monsoon trough of low pressure on March 5, about 485 km (300 mi) to the southeast of Honiara, on the Solomon Island of Guadalcanal.[12][13] Over the next 3 days the system remained as a shallow depression as it moved southwards, before it rapidly developed into a tropical cyclone underneath an upper-level ridge of high pressure.[12][14] During March 8, the JTWC classified the system as Tropical Cyclone 22P and initiated advisories on the system, while it was named Yali by the FMS after it had developed into a Category 1 tropical cyclone on the Australian scale.[9][12] During the next day Yali continued to intensify before as the ridge of high pressure moved northwards, before the system peaked with 1 and 10-minute sustained windspeeds of 120 km/h (75 mph).[13][14] This made it equivalent to a category 3 severe tropical cyclone on the Australian scale and a category 1 hurricane on the SSHWS.[13] Yali rapidly weakened and dissipated over water during March 11.[12][13] Despite being within the vicinity of both Vanuatu and New Caledonia, the system did not pass close enough to affect or cause any damage to any inhabited islands.[11][12]

On May 20, TCWC Nadi started to monitor a tropical depression that had developed about 1,440 km (895 mi) to the northeast of Port Vila, Vanuatu.
Other system
In addition to 12 named cyclones, one other system developed during the season. Cyclone 13P existed from February 2 to February 5.
