During the season twelve tropical cyclones were recorded within the South Pacific basin, which was considered above average when compared to an 18-year average of 10 systems.

Systems

Tropical Cyclone Osea

Tropical Cyclone Osea formed about Шаблон:Convert to the north-northeast of Port Vila on 21 November. It moved on a southerly track parallel to Vanuatu and spent most of its time over the sea. No significant damage was reported.

Tropical Cyclone Patsy

On December 12, TCWC Nadi started to monitor a tropical depression that had developed about Шаблон:Convert to the north-northwest of Suva, Fiji.

The system affected Northern Vanuatu but caused little or no damage to the island nation.

Severe Tropical Cyclone Raja

Шаблон:Infobox tropical cyclone small Шаблон:Main Cyclone Raja existed from December 21, 1986, to January 5, 1987.

Severe Tropical Cyclone Sally

Шаблон:Infobox tropical cyclone small Cyclone Sally existed from December 26, 1986, to January 6, 1987. It caused A$35 million of damage in the Cook Islands, making a thousand people homeless on Rarotonga and severely damaging 80% of the buildings in Avarua.

Severe Tropical Cyclone Tusi

Шаблон:Infobox tropical cyclone small Шаблон:Main 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. 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 Шаблон:Convert. 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 10th.

Tropical Cyclone Veli

The precursor tropical low to Cyclone Veli formed within the Australian region on February 5, about Шаблон:Convert to the south-east of Port Moresby in Papua New Guinea. 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 Шаблон:Convert. 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. 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. Early the next day the JTWC initiated advisories and started to monitor Veli as Tropical Cyclone 16P, with peak 1-minute sustained windspeeds of Шаблон:Convert. During that day strong upper level north-westerlies caused vertical windshear to increase over Cyclones Veli and Uma and thus weakened them. During February 9, Cyclone Veli absorbed Uma and formed a complex low, which moved slowly south-eastwards and became extratropical. Damage within Vanuatu was either minimal or went unreported, as the island nation was more concerned with the aftermath of Cyclone Uma.Шаблон:Vanuatu Tropical Cyclones

Severe Tropical Cyclone Wini

Шаблон:Infobox tropical cyclone small Cyclone Wini existed from February 27 to March 7.

Severe Tropical Cyclone Yali

A shallow tropical depression developed within a monsoon trough of low pressure on March 5, about Шаблон:Convert to the southeast of Honiara, on the Solomon Island of Guadalcanal. 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. 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. 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 Шаблон:Convert. This made it equivalent to a category 3 severe tropical cyclone on the Australian scale and a category 1 hurricane on the SSHWS. During the next day, Yali rapidly weakened and dissipated over water during March 11. 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.

Tropical Cyclone Zuman

Шаблон:Infobox tropical cyclone small Cyclone Zuman existed from April 19 to April 26.

Tropical Cyclone Blanch

Шаблон:Infobox hurricane small On May 20, TCWC Nadi started to monitor a tropical depression that had developed about Шаблон:Convert to the northeast of Port Vila, Vanuatu.

Other systems

In addition to 12 named cyclones, two other systems developed during the season. Cyclone 13P existed from February 2 to February 5. Another system, 19P, existed from February 28 to March 3.
