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 (90 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. {{clear}}Severe Tropical Cyclone Uma{{Infobox Hurricane Small|Basin=SPac |Image=Uma Feb 7 1987 0352Z.png |Track=Uma 1987 track.png |Formed=February 4 |Dissipated=February 10 |Pressure=940 |10-min winds=90 |1-min winds=75 }} Cyclone Uma existed from February 4 to February 10. {{clear}}Tropical Cyclone Veli{{Infobox Hurricane Small|Basin=SPac |Image=Veli Feb 7 1987 0300Z.png |Track=Veli 1987 track.png |Formed=February 7 |Dissipated=February 9 |Pressure=987 |10-min winds=45 |1-min winds=25 }} The precursor tropical low to Cyclone Veli formed within the Australian region on February 5, about {{convert|725|km|mi|round=5|abbr=on}} 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 {{convert|85|km/h|mph|round=5|abbr=on}}. 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.[5] During that day the system continued to move eastwards, before as it passed near to Espitru Santo, Veli started to move steadily towards the south-east.[5] Early the next day the JTWC initiated advisories and started to monitor Veli as Tropical Cyclone 16P, with peak 1-minute sustained windspeeds of {{convert|45|km/h|mph|round=5|abbr=on}}.[6][7] During that day strong upper level north-westerlies caused vertical windshear to increase over Cyclones Veli and Uma and thus weakened them.[5] During February 9, Cyclone Veli absorbed Uma and formed a complex low, which moved slowly south-eastwards and became extratropical.[5] Damage within Vanautu was either minimal or went unreported, as the island nation was more concerned with the aftermath of Cyclone Uma.{{Vanuatu Tropical Cyclones}} {{clear}}Severe Tropical Cyclone Wini{{Infobox Hurricane Small|Basin=SPac |Track=Wini 1987 track.png |Formed=February 27 |Dissipated=March 7 |10-min winds=70 |1-min winds=65 |Pressure=965 }} Cyclone Wini existed from February 27 to March 7. {{clear}}Tropical Cyclone Unnamed/19P{{Infobox Hurricane Small|Basin=SPac |Track= |Formed=February 28 |Dissipated=March 3 |10-min winds=50 |1-min winds=40 |Pressure=985 }}{{clear}} Severe Tropical Cyclone Yali{{Infobox Hurricane Small|Basin=SPac |Track=Yali 1987 track.png |Formed=March 5 |Dissipated=March 11 |10-min winds=65 |1-min winds=65 |Pressure=970 }} A shallow tropical depression developed within a monsoon trough of low pressure on March 5, about {{convert|485|km|mi|round=5|abbr=on}} to the southeast of Honiara, on the Solomon Island of Guadalcanal.[8][9] 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.[8][10] 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.[6][8] 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 {{Convert|120|km/h|mph|abbr=on|round=5}}.[9][10] This made it a category 3 severe tropical cyclone on the Australian tropical cyclone intensity scale and equivalent to a category 1 hurricane on the Saffir-Simpson hurricane scale.[9] During the next day Yali rapidly weakened and dissipated over water during March 11.[8][9] 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.[8] {{clear}}Tropical Cyclone Zuman{{Infobox Hurricane Small|Basin=SPac |Track=Zuman 1987 track.png |Formed=April 19 |Dissipated=April 26 |10-min winds=55 |1-min winds=55 |Pressure=975 }} Cyclone Zuman existed from April 19 to April 26. {{clear}}Tropical Cyclone Blanch(e){{Infobox hurricane small|Basin=Aus |Formed=May 20 |Dissipated=May 22 (exited basin) |Track=Blanch 1987 track.png |10-min winds=40 |1-min winds= |Pressure=990 }} On May 20, TCWC Nadi started to monitor a tropical depression that had developed about {{convert|1440|km|mi|round=5|abbr=on}} to the northeast of Port Vila, Vanuatu.{{TCWC Wellington BT}} {{Clear}}Other systemsIn addition to 12 named cyclones, two other systems developed during the season.
