1986–87 South Pacific cyclone season
The 1986–87 South Pacific cyclone season was an above average tropical cyclone season. A total of 12 tropical cyclones developed during the season, 6 of which became severe tropical cyclones.
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.
Tropical Cyclone Osea formed about 565 km (350 mi) 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.
On December 12, TCWC Nadi started to monitor a tropical depression that had developed about 1,000 km (620 mi) to the north-northwest of Suva, Fiji.
The system affected Northern Vanuatu but caused little or no damage to the island nation.
Cyclone Raja existed from December 21, 1986, to January 5, 1987.
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.
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 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.
