On December 19, the remnants of Tropical Cyclone Felicity, moved into the basin with 10-minute sustained windspeeds of 75 km/h (45 mph), which would have made it a category 1 tropical cyclone on the Australian scale.{{TCWC Wellington BT}} However, because it did not have the "classical characteristics of a tropical cyclone", it was treated as a tropical depression by the BoM and the FMS.{{cite report|url=http://www.bom.gov.au/cyclone/history/felicity.shtml |title=Tropical Cyclone Felicity |publisher=Australian Bureau of Meteorology |access-date=April 7, 2012 |archive-url=https://web.archive.org/web/20120410174132/http://www.bom.gov.au/cyclone/history/felicity.shtml |archive-date=April 10, 2012 |url-status=live }}{{cite journal|author=Singh, Arveen K |journal=Mariners Weather Log |volume=34 |issue=3|date=Summer 1990|title=Tropical depression in Coral Sea (former T.C.

There were no reports of any damage associated with this depression within New Caledonia, which was largely due to its small and not so intense nature of the system.

{{Main article|Cyclone Ofa}}

On January 27, a shallow tropical depression formed within the South Pacific Convergence Zone, about {{convert|430|km|mi|round=5|abbr=on}} to the southeast of Funafuti, Tuvalu.{{cite report|author=Fiji Meteorological Service|type=Mariners Weather Log|volume=34|issue=3|date=Summer 1990|oclc=648466886|issn=0025-3367|publisher=United States National Oceanic and Atmospheric Administration's National Oceanographic Data Service|editor=DeAngellis, Richard M|pages=23–25|title=Tropical Cyclone Ofa|hdl=2027/uiug.30112104094245}} Over the next two days the system developed little and remained slow moving, near the Tuvaluan atoll of Funafuti. During January 30, the depression moved towards the north-east and started to organize, as pressures near the systems center rapidly falling. During the next day the system subsequently started to curve south-eastwards and away from Tuvalu, before the NWOC initiated advisories on the system and designated it as Tropical Cyclone 13P.{{cite report|title=Tropical Cyclone Ofa, January 31 - February 7, 1990 |date=May 3, 1990 |publisher=Fiji Meteorological Service |type=Tropical Cyclone Report 90/4 |author=Prasad, Rajendra |access-date=May 12, 2014 |archive-date=February 22, 2014 |url=http://www.pacificdisaster.net/pdnadmin/data/original/JB_DM393a_TC_Ofa_FMS_1990_Report.pdf |archive-url=https://web.archive.org/web/20140222011918/http://www.pacificdisaster.net/pdnadmin/data/original/JB_DM393a_TC_Ofa_FMS_1990_Report.pdf |url-status=dead }}{{cite report|publisher=United States Joint Typhoon Warning Center|title=Annual Tropical Cyclone Report: 1990|url=http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/atcr/1990atcr.pdf|access-date=December 21, 2021|date=|archive-date=October 19, 2016|archive-url=https://web.archive.org/web/20161019075456/http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/atcr/1990atcr.pdf|url-status=dead}} Late on January 31, TCWC Nadi named the tropical depression Ofa, after it had developed into a category 1 tropical cyclone on the Australian scale.{{TCWC Wellington BT}} Over the few days the system moved towards the south-southeast and intensified further. Ofa subsequently passed about {{convert|110|km|mi|round=5|abbr=on}} to the west of the Western Samoan Island of Savai'i between 10:00 and 18:00 UTC during February 3. Early the next day as the system started to accelerate towards the south-southeast towards the island nation of Niue, the NWOC estimated that Ofa had peaked with 1-minute sustained wind speeds of 215 km/h (130 mph), which made it equivalent to a category 4 hurricane on the SSHWS.{{cite web|publisher=United States Navy, United States Air Force|title=Tropical Cyclone 13P (Ofa) best track analysis|url=http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/best_tracks/1990/1990s-bsh/bsh131990.txt|archive-url=https://web.archive.org/web/20110606235536/http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/best_tracks/1990/1990s-bsh/bsh131990.txt|url-status=dead|archive-date=June 6, 2011|author=Naval Pacific Meteorology and Oceanography Center|author2=Joint Typhoon Warning Center|access-date=March 13, 2013}} Later that day TCWC Nadi also estimated that the system had peaked with 10-minute sustained wind speeds of 185 km/h (115 mph) as a category 4 severe tropical cyclone,. During February 5, the system passed about {{convert|55|km|mi|round=5|abbr=on}} to the west of Niue, as it started to weaken and started to transition into an extratropical cyclone. The system completed this transition during February 8, before the remnants were last noted during February 10 after they had performed a small clockwise loop.

Cyclone Ofa affected seven different island nations and caused gales or much stronger winds in six of those countries which resulted in damage ranging from moderate to very severe. Storm tide from the cyclone which is the combined effect of storm surge and high tide caused havoc in several countries and was the major cause of destruction. Overall the system killed at least eight people while it was estimated that the overall damage would amount to over {{ntsp|180000000||US$}} with damage totals of at least {{ntsp|150000000||US$}} and {{ntsp|30000000||US$}} in Western and American Samoa.

On January 31, the FMS reported that a tropical depression had moved south-eastwards into the basin from the Australian region and named it Nancy, after it had become a category 1 tropical cyclone on the Australian scale.{{cite report |author=Koop, Neville L |title=Tropical Cyclone Nancy, 27 January - 4 February |date=May 3, 1990 |url=https://webapp1.dlib.indiana.edu/virtual_disk_library/index.cgi/4274123/FID1030/DATA/TROPIC/SWP_NAR/1990_4.NAR|publisher=Fiji Meteorological Service |archive-date=30 June 2022 |access-date=November 28, 2022|archive-url=https://web.archive.org/web/20220630123635/https://webapp1.dlib.indiana.edu/virtual_disk_library/index.cgi/4274123/FID1030/DATA/TROPIC/SWP_NAR/1990_4.NAR|url-status=live}}{{cite report|title=Tropical Cyclone Nancy |url=http://www.bom.gov.au/cyclone/history/nancy.shtml |access-date=November 28, 2022|archive-date=May 29, 2014 |publisher=Australian Bureau of Meteorology |archive-url=https://web.archive.org/web/20140529084341/http://www.bom.gov.au/cyclone/history/nancy.shtml |url-status=live }} During that day, Nancy recurved south-westwards around the southern extension of an upper-level trough of low pressure and moved back into the Australian region. The system subsequently re-entered the basin as an extratropical cyclone on February 6, before it dissipated to the west of New Zealand on February 8.{{cite web|url={{IBTRACS url|id=1990027S18156}}|title=1990 Tropical Cyclone Nancy (1990027S18156)|publisher=International Best Track Archive for Climate Stewardship|access-date=November 28, 2022}}

While the system was located within the basin, the FMS reported that the system had peaked as a category 1 tropical cyclone, with 10-minute sustained winds of {{convert|45|kn|km/h mph|abbr=on|round=5|order=out}}. The JTWC also monitored the system while it was in the basin

and estimated that Nancy had peak 1-minute sustained winds of {{convert|65|kn|km/h mph|round=5|abbr=on|order=out}}, which made it equivalent to a category 1 hurricane on the SSHWS. The BoM later reanalysed the system and found that it had peaked as a category 2 tropical cyclone, with 10-minute sustained winds of {{convert|60|kn|km/h mph|abbr=on|round=5|order=out}} while it was located within the basin.{{BoM TC Database}}

On February 6, the FMS reported that a depression had developed, within the South Pacific Convergence Zone near the islands of Tuvalu.{{cite report|author=Koop, Neville L|author2=Fiji Meteorological Service|type=Mariners Weather Log: Volume 35, Issue 1: Winter 1991|year=1991|title=Samoa Depression|oclc=648466886|publisher=United States National Oceanic and Atmospheric Administration's National Oceanographic Data Service|page=53|editor=DeAngellis, Richard M|hdl=2027/uiug.30112104094104|issn=0025-3367}} Over the next few days the system was steered towards the southeast by a north-westerly steering flow on the eastern side of an upper-level trough of low pressure. As the depression moved towards the southeast it passed in between Western Samoa and the northern islands of Tonga before it came very close to Niue during February 8. Despite marginal gale-force winds being present in the depressions eastern quadrant, strong north-westerlies prevented the depression, from strengthening into a tropical cyclone. The depression was subsequently last noted during February 9, as it was absorbed into the Westerlies. The only damage that could be attributed to the depression is a number of houses that were destroyed on the Tuvaluan atoll of Vaitupu on February 6, however it is possible that the houses were destroyed by the strong and squally north-westerly winds that were prevailing over the northern islands of Tuvalu at that time. As Tuvalu, Western Samoa, American Samoa, Tonga, Niue had all been affected by Cyclone Ofa a few days earlier; any damage would have been difficult to assess.

{{main|Cyclone Peni}}A shallow area of low-pressure began to develop near Rakahanga, an island in the Cook Island chain. The storm had also formed on the South Pacific convergence zone. The storm was first recognized on February 12, and had received tropical cyclone characteristics on the 13th. At 21:00 UTC, the storm was recognized as Tropical Cyclone Peni. The storm then took a path southwest towards the Cook Islands, Peni made a narrow turn and passed close to Aitutaki. Peni had gained hurricane status on the 15th, at 06:00 UTC. Peni had been able to keep hurricane characteristics until February 17, when it was downgraded to a storm, and soon, was declared extratropical. The name Peni was retired from the naming list.{{clear}}

The depression continued to move south-westwards for the next 30 hours, before it curved southwards as it started to intensify slowly. During March 22, the JTWC initiated advisories on the system and designated it as Tropical Cyclone 26P, before the FMS named the system Rae later that day, after it had accelerated eastwards.

The JTWC and the FMS both estimated during March 23, that the system had peaked with winds of {{convert|50|kn|km/h mph|round=5|order=out|abbr=on|sortable=on}}, which made it a Category 2 tropical cyclone on the Australian Scale.{{cite web|publisher=International Best Track Archive for Climate Stewardship|title=1990 Tropical Cyclone Rae (1990076S12165)|url={{IBTRACS url|id=1990076S12165}}|access-date=December 27, 2021}} At this time, the system was located about {{convert|225|km|mi|round=5|abbr=on|sortable=on}} to the south of Kadavu in Fiji and had started to move south-eastwards towards higher latitudes. Rae subsequently weakened as it experienced stronger vertical windshear and cooler sea surface temperatures, which caused the system to weaken and lose its tropical characteristics. The system degenerated into a depression during March 24, as it maintained its south-eastwards track, before it dissipated to the south of Niue during the next day. The system impacted Fiji between March 19 - 24, where it caused strong winds and landslides, as well as minor damage to trees, houses and crops. Torrential rain associated with the system helped to ease a drought and caused flooding to be reported across the archipelago.{{cite report|title=Flooding in the Fiji Islands between 1840 and 2009|page=37|publisher=Risk Frontiers|author2=Yeo, Stephen W|date=October 1, 2010|access-date=December 27, 2021|author3=Devi, Swastika|author=McGree, Simon|url=https://www.riskfrontiers.com/pdf/Floods%20in%20Fiji%201840-2009%20-%20Risk%20Frontiers%20final.pdf|archive-date=July 12, 2020|archive-url=https://web.archive.org/web/20200712040629/https://www.riskfrontiers.com/pdf/Floods%20in%20Fiji%201840-2009%20-%20Risk%20Frontiers%20final.pdf}} Within the island nation, the floods were responsible for three deaths in flooded rivers, as well as disruption to transport services, water and electricity supplies.
