Part of the 2017–18 South Pacific cyclone season

Severe Tropical Cyclone Gita was the most intense tropical cyclone to impact Tonga since reliable records began. The second named storm and first major tropical cyclone of the 2017–18 South Pacific cyclone season, Gita originated from a monsoon trough that was active in the South Pacific in early February 2018. First classified as a tropical disturbance on 3 February, the nascent system meandered near Vanuatu for several days with little development. After acquiring a steady east trajectory near Fiji, it organized into a Category 1 tropical cyclone on 9 February near Samoa. Arcing south in a clockwise turn, the system rapidly intensified, and became a severe tropical cyclone on 10 February near Niue.

Throughout its path in the South Pacific, Cyclone Gita affected multiple island nations and territories. Tonga was the hardest-hit, with severe damage occurring on the islands of Tongatapu and ʻEua; two fatalities and forty-one injuries occurred in the kingdom. At least 171 homes were destroyed and more than 1,100 suffered damage. Violent winds destroyed homes and left the two islands largely without power. Torrential rains and damaging winds caused widespread disruptions in Samoa and American Samoa, prompting emergency declarations in both. Outlying islands in the Fijian Lau Islands were significantly affected, particularly Ono-i-Lau and Vatoa. Wallis and Futuna, Niue, and Vanuatu were also affected, but impacts in those areas were minor. Total damage from Gita is estimated to be in excess of US$252 million, primarily in American Samoa and Tonga.

Meteorological history

On 3 February, the Fiji Meteorological Service (FMS) started to monitor Tropical Disturbance 07F, [1] :7–8 which had developed within a trough of low pressure, about 435 km (270 mi) to the southeast of Honiara in the Solomon Islands. [2] [3] The system was poorly organized and was located along an upper-level ridge of high pressure, in an area of high vertical wind shear. [3] Over the next couple of days, the system moved erratically near northern Vanuatu and remained poorly organized, with convection located to the south of the low-level circulation center. [4] The system subsequently started to move south-eastwards, towards the Fijian Islands and a favorable environment for further development, on 5 February. [5] The system subsequently passed near the island nation during 8 February, where it developed into a tropical depression and started to move north-eastwards towards the Samoan Islands. [6] [7] During 9 February, the United States Joint Typhoon Warning Center (JTWC) initiated advisories on the system and designated it as Tropical Cyclone 09P, after an ASCAT image showed that it had winds of 65–75 km/h (40–45 mph) in its northern semicircle. [8] The FMS subsequently named the system Tropical Cyclone Gita early, after the United States National Weather Service Weather Forecast Office in Pago Pago requested that the system be named early for warning and humanitarian reasons. [9]

After Gita was named, a prolonged period of rapid intensification ensued as it quickly intensified into a Category 1 tropical cyclone on the Australian tropical cyclone intensity scale, before it passed within 100 km (60 mi) of Samoa and American Samoa. After moving past the Samoan Islands, Gita turned southeast, then southwards, under the influence of a near-equatorial ridge to the northeast. [10] On 10 February, Gita rapidly intensified to a category 3 severe tropical cyclone on the Australian scale [11] while traversing anomalously warm sea surface temperatures of between 28–29 °C (82–84 °F). [12] The system bypassed Niue to the east during this intensification phase. [1] :7 On 11 February, Gita continued to intensify into a category 4 severe tropical cyclone. [13] At the same time, Gita turned westward under the influence of a subtropical ridge to the south. [10] Around 12:00  UTC on 12 February, the cyclone passed near or over the Tongan islands of ʻEua and Tongatapu as a high-end Category 4 severe tropical cyclone. [14] [15] At this time, maximum 10-minute sustained winds were estimated at 195 km/h (120 mph) making Gita the strongest cyclone to strike the nation since reliable records began. [14] [16] The JTWC estimated the system to have reached its overall peak intensity at this time as a Category 4-equivalent on the Saffir-Simpson scale with 1-minute sustained winds of 230 km/h (145 mph). [14]

At 18:00 UTC on 13 February, Gita reached its peak strength approximately 205 km (125 mi) south of Kandavu, Fiji, as a Category 5 severe tropical cyclone with ten-minute sustained winds of 205 km/h (125 mph), gusts to 285 km/h (180 mph), a minimum pressure of 927 mbar (hPa; 27.37 inHg). [1] :7 [14]

Impact

Gita impacted the Pacific island nations and territories of Vanuatu, Fiji, Wallis and Futuna, Samoa, American Samoa, Cook Islands, Niue, Tonga, New Caledonia, and New Zealand, with the most significant damage being reported in the Samoan Islands and Tonga. Owing to the cyclone's significant and widespread impact, the name Gita was retired following its usage and will never be used for a South Pacific tropical cyclone again. [17] :25

Gita brought torrential rain to parts of Samoa on 8–9 February. [31] Accumulations averaged 150–250 mm (5.9–9.8 in) across the country, peaking at 320 mm (13 in) along the eastern slops of Mount Le Pu'e on Upolu. [25] [32] Storm-force winds impacted the nation, reaching 99.7 km/h (62.0 mph) at Faleolo International Airport and 98.2 km/h (61.0 mph) in Apia. [25] Multiple rivers in the city burst their banks and inundated homes. [33] At least 233 people sought refuge in emergency shelters. [31] Landslides and flooding rendered many roads impassable. [34] Communications were briefly lost with the southern coast of Upolu. [33] A state of disaster was declared for the nation on 10 February. [33] Damage to the power grid reached $10 million. [26] No casualties were reported nationwide. [25]

American Samoa

On 8 February, the National Weather Service (NWS) office in Pago Pago issued a tropical storm watch, a high surf advisory, and a flash flood watch for all of American Samoa as the nascent cyclone approached the territory. [35] With Tropical Depression 08F existing simultaneously to the south of Fiji, uncertainty existed in the exact track of Gita. However, NWS Forecasters emphasized the risk of flash floods and mudslides as the interaction of two cyclones led to persistent monsoonal flow across the region. [36] In the two days preceding Gita's arrival, this monsoon trough produced significant rains, reaching 432 mm (17.0 in). [30] Monsoonal rains continued for two days after Cyclone Gita, and the flash flood watch was finally discontinued on 12 February. [37] The American Samoa Emergency Management Agency advised residents to "remain on alert and secure loose items as necessary". [35] The tropical storm watch was soon upgraded to a warning, indicating the expected arrival of gale-force winds within 36 hours. [38] Pago Pago International Airport suspended operations for the duration of the storm. [39] The NWS discontinued the tropical storm warning late on 9 February as Gita moved away from the territory. [40]

Cyclone Gita reached American Samoa on 9 February, bringing heavy rains and strong winds from 4:00 a.m. to 2:00 p.m. local time. [19] The strongest winds were recorded at the NOAA Earth System Research Laboratory Office in Cape Matatula on Tutuila; sustained values reached 119 km/h (74 mph) and gusts peaked at 157 km/h (98 mph). [19] These winds tore roofs of structures and downed trees and power lines across the territory, [41] with the most severe damage reported in Nu'uuli and Tafuna. [42] Approximately 90 percent of the island was left without power and water and nearly 1,000 people required evacuation. [19] [43] The NWS Office lost power; the Honolulu, Hawaii, office issued forecasts in the interim. [41] Rainfall in Pago Pago exceeded 155 mm (6 in). [32] Flash floods and mudslides occurred territory-wide, with valleys and low-lying areas being most affected. [39] Multiple streams flooded and prompted evacuations in Malaeloa village. Landslides were reported in Avau, Amanave, and Poloa. [44] Approximately 3,000 people reported damage to their crops. [45] Destruction of banana, papaya, and breadfruit crops temporarily limited the availability of food. [46] :52

Offshore, the cargo ship Uila o le Sami sank near Taʻū during the storm. [19] Approximately 300 yd (270 m) off Leone Bay, the Taiwanese-flagged fishing vessel Chui Kai Fa No. 1 grounded on 5 February and split in half. [47] [48] The vessel was previously adrift in international waters following a fire on 4 November 2017. [49] The grounding of the Chui Kai Fa No. 1 prompted the closure the closure of the port of Pago Pago until 11 February. [48] [50] The vessel contained an estimated 13,000–30,000 US gal (49,000–114,000 L) of diesel fuel and a light oil sheen was reported in the area. [47] Inclement weather produced by Cyclone Gita impeded response efforts by the United States Coast Guard. [49]

An assessment by the American Samoa Public Works in March 2018 determined that Cyclone Gita destroyed 387 homes, inflicted major damage to more than 1,300 homes, and damaged a further 1,600. [51] [52] The American Samoa Department of Commerce estimated that half of the territory's population suffered some form of property loss and placed total damage at US$200 million. [18] :5 A 2019 report by the American Samoa Economic Forecast calculated combined direct and indirect losses at US$186 million. [53] The National Centers for Environmental Information calculated a lower damage total of US$52 million. In contrast to the scale of damage, no fatalities or injuries were reported. [19]

On 10 February, a Coast Guard AC-130 conducted aerial surveys of the territory and a small group of Federal Emergency Management Agency (FEMA) personnel were deployed. [50] [39] By 18 April, almost 100 federal personnel were deployed to the territory. [54] United States President Donald Trump declared a state of emergency for American Samoa on 11 February. [55] The United States Army Reserve assisted FEMA and the American Red Cross with the deployment of personnel and distribution of relief supplies. Furthermore, the Army Reserve Pago Pago facility was converted into a staging area for the disaster response. [56] The United Nations Development Programme initiated a US$100,000 response plan on 16 February to support the local governmental response. [57] President Trump later declared the territory a major disaster area on 2 March. [58] Following this declaration, the Internal Revenue Service announced that residents could apply for tax exemptions. [59] Health officials advised residents to boil water amid an enhanced risk of dengue fever. [41] StarKist Samoa donated US$50,000 to the American Samoa Government on 16 March. [60] On 9 April 2019, Representative Nita Lowey (D-NY) introduced the Additional Supplemental Appropriations for Disaster Relief Act, 2019 (H.R. 2157) bill to the 116th Congress. The bill, signed into law by President Trump on 6 June, provided just over US$17.2 billion for disaster recovery nationwide; of this US$18 million was allocated for American Samoa and made available through February 2020. [61] However, distribution of these funds was delayed and Governor Lolo Matalasi Moliga urged the United States Department of Agriculture to expedite the process. [62] Through March 2021, FEMA provided US$31,198,512.50 in financial assistance: $20,543,787.44 in individual funds, US$9,763,391.26 for public assistance, and US$891,333.80 for a hazard mitigation program. [63] A further US$40 million was provided through the Small Business Administration, intergovernmental agreements, disaster grants, and private distributions. [18] :15

A prolonged downturn in the territory's tuna industry in the decade preceding Gita led to an economic recession. [18] :16 The nationwide reconstruction efforts and the influx of money in the wake of the cyclone spurred slight growth of the American Samoa economy, reflecting in the gross domestic product increasing by 2.2 percent in 2018, [18] :12 and a pause in the recession. [18] :17 This economic stimulation quickly subsided and American Samoa's economy contracted in 2019. [18] [53]

Tonga

Prior to and during the cyclone, approximately 5,700 residents sought refuge in public shelters. [64] [65] Power was turned off prior to the storm's arrival. [65] Striking Tonga on 12 February, Cyclone Gita brought destructive winds to the capital island of Tongatapu. [16] Initial surveys across the island revealed 119 homes destroyed and another 1,131 damaged, [66] primarily in Nukuʻalofa. [67] Many areas were left without water and power. [16] Many structures lost their roof during the height of the storm. [64] Older structures suffered the greatest damage, including the Tongan Parliament building, built more than 100 years ago, which was flattened by the storm. [64] [65] Fuaʻamotu International Airport sustained damage, along with the domestic terminal, prompting officials to keep the airport closed. Across Tongatapu, 3 people suffered major injuries while another 30 experienced minor injuries. [28] An elderly woman died while trying to find shelter after her home was destroyed. [29] One person died from a heart attack potentially related to the storm in Fuaʻamotu. [28]

On the neighboring island of ʻEua, the storm knocked out power to all residents and caused extensive damage. Similar to Tongatapu, older structures suffered severe damage while newer buildings fared well. Crops were largely destroyed. [28] Fifty-two homes were completely destroyed on the island; eight people suffered injury, including one severe. [66] Total damage were estimated at T$356.1 million (US$164.1 million), [27] including a NZ$20 million (US$14.5 million) damage to the power grid. [68]

Immediately following the storm, a curfew was imposed for all of Tonga. Personnel from His Majesty's Armed Forces rescued people during the storm and began clearing roads at daybreak on 13 February. National Emergency Management Office spokesman Graham Kenna called the storm "the worst situation [he has] been in" during his 30-year career. [28] MP Lord Fusituʻa described the impact as the worst since at least Cyclone Isaac in 1982. [29] India provided US$500,000 humanitarian aid to Tonga under UNOSSF. On 13 February, Australia provided A$350,000 (US$275,000) in emergency supplies via the Royal Australian Air Force (RAAF) to assist more than 2,000 people. Australia also sent humanitarian supplies to the Tongan Red Cross. Two civilian humanitarian specialists were deployed to assist Tonga's National Emergency Management Office. A medical expert also provided assistance to assess health infrastructure. [69] New Zealand provided NZ$750,000 (US$544,000) in assistance. [65]

Fiji

During Gita's formative states on 6–8 February, the depression brought heavy rain and gusty winds to northern Fiji resulting in some flooding. [1] :7 Accordingly, the FMS issued alerts for these hazards across the affected regions. [70] Rainfall reached 108 mm (4.3 in) in Udu Point on 6 February. [71]

On 13 February, the center of Gita passed roughly 60 km (37 mi) south of Ono-i-Lau in the Lau Islands of Fiji. [72] Observations from the island revealed peak sustained winds of 135 km/h (84 mph) with gusts to 190 km/h (120 mph). Twenty-four hour rainfall reached 270.7 mm (10.66 in), greatly contributing to the island experiencing its wettest February on record; the monthly total was 887.9 mm (34.96 in). [71] Flooding from tidal surge preceded the core of the cyclone by several hours. [73] Structural damage was reported in Doi Village, including one home that lost its roof. [74] Communications with Ono-i-Lai and nearby Vatoa were disrupted for roughly a day. [75] [67] Across both islands, 10 homes were destroyed and 26 more sustained damage. [76] Many structures sustained roof damage and crops were devastated. [67] Local leaders on Ono-i-Lau called the storm the "worst in living memory". [77] Damage to the nation were at FJ$1.23 million (US$606,000). [21]

New Caledonia

On 16 February, the New Caledonia branch of Météo-France issued a level 1 hurricane alert for the Isle of Pines, southeast Grande Terre. [78] This was soon raised to level 2, prompting the closure of schools and businesses across the municipality. [79] In advance of the storm, most tourists visiting Isle of Pines were evacuated to Nouméa; however, many stayed to ride out the storm. Municipal buildings were opened to the public as shelters. [80] Domestic flights at Nouméa Magenta Airport were suspended during the storm's passage. [81] Offshore, removal operations of the grounded cargo ship Kea Trader —situated over Récif Durand about 220 km (140 mi) east of Nouméa [82] —were suspended with workers repositioned to Nouméa. The two broken halves of the ship were ballasted to minimize movement in the expected rough seas. [83] The cyclone ultimately had little effect across the territory; some damage to vegetation and marinas was reported. [22]

While located nearly 1,000 km (620 mi) east of Queensland on 17 February, large swells propagating from the cyclone impacted Australia's Pacific beaches. Conditions remained hazardous through 19 February. Surf was largest from Gold Coast to Sydney, with peak swells of 6 m (20 ft) at Tweed Heads and 4.5 m (15 ft) at Palm Beach. [84] Surf Life Saving Queensland closed all beaches between North Kirra and Southport. Although most people heeded warnings and closures, some "thrillseekers" surfed and used jet skis. One person required rescue in the Jumpinpin Channel. [85] A surfer and swimmer were pulled from dangerous rip currents at Burleigh and Mooloolaba, respectively. [86] Off Nambucca Heads, New South Wales, one person was pulled out to sea by rip currents on 17 February. Surf Life Saving New South Wales stated that rescue operations shifted to recovery the following day as there had been "a significant amount of time since this gentleman disappeared". [87] Helicopters conducted aerial surveys on 19 February to assist local police and rescuers. [88] Search and rescue operations were ultimately suspended on 21 February without success. [20] Two people were rescued off the coast of Manly when there boat sank amid 2 m (6.6 ft) swells. Throughout New South Wales, authorities conducted dozens of rescues. [87]

New Zealand

As Cyclone Gita threatened to hit New Zealand as a strong ex-tropical cyclone, New Zealand's MetService issued heavy rain warnings and strong wind warnings covering a wide expanse of the country. [89] [90] Campers, hikers, and boaters in the Marlborough Sounds were told to evacuate, and residents there were warned that communications could be cut off by the storm. [91] Several schools in the region of Nelson were closed, [89] while in the West Coast, schools in the districts of Buller and Grey were closed. [92] Air New Zealand cancelled a number of flights on 20 February. [93]

As Gita bore down on the South Island, bringing floods and strong winds, a state of emergency was eventually declared on 20 February. [94] Total insured losses across New Zealand reached NZ$35.6 million (US$26.1 million). [23] In Taranaki, Gita resulted in NZ$4.5 million (US$3.1 million) worth of damage. A tree fell on a water main near the water treatment plant south of New Plymouth, leaving 10,000 homes without water for 3 days and 26,000 homes on a boil water notice for 7 days. [95]

Other nations

As Gita's precursor tropical disturbance impacted Vanuatu's Torba province during 6 February, the Vanuatu Meteorology and Geo-hazards Department warned that heavy rainfall, thunder and lightning would impact the area and advised people to take extra precautions. [96] Additional alerts were raised on 15–16 February as Gita tracked southeast of the nation. [97] Between 8 and 9 February, the system brought strong winds and heavy rain to Wallis and Futuna. Some power outages were reported on Wallis, though overall effects were negligible. [30] On 8 February, weather alerts were issued for Niue as Gita approached from the northeast. [98] The cyclone bypassed the island to the southeast the following day with minimal effects. [24] Sustained winds at Niue International Airport reached 40 km/h (25 mph) with gusts to 64 km/h (40 mph). [98]

Cyclone Heta

Severe Tropical Cyclone Heta was a powerful Category 5 tropical cyclone that caused moderate damage to the islands of Tonga, Niue, and American Samoa during late December 2003 and early January 2004. Heta formed on December 25, 2003; it reached a maximum intensity of 260 km/h (160 mph) and an estimated pressure of 915 hPa before dissipating on January 11, 2004. It was the first tropical cyclone to form in the area of responsibility of the regional specialised meteorological centre (RSMC) at Nadi, Fiji, during the 2003–04 South Pacific cyclone season.

Cyclone Olaf

Cyclone Olaf was the sixth cyclone to form in the Southwest Pacific Ocean during the 2004–05 South Pacific cyclone season. Olaf was also one of three simultaneous cyclones to form during the 2004–05 season, forming 21 hours after Cyclone Nancy formed to the east. A powerful Category 5 cyclone, Olaf stuck American Samoa causing heavy damage although exact estimates are unknown. Despite the damage, there were no reported deaths or injuries from the cyclone. Olaf was third South Pacific cyclone to hit the Cook Islands during the 2004–05 season, and Cyclone Percy would later affect the already devastated archipelago less than 2 weeks later.

Cyclone Percy Category 5 South Pacific cyclone in 2005

Cyclone Percy was the seventh named storm of the 2004–05 South Pacific cyclone season and the fourth and final severe tropical cyclone to form during the 2004–05 South Pacific cyclone season. Cyclone Percy originated as a tropical disturbance on February 23. Over the course of the next few days, the system organized while moving east-southeastward, before intensifying into a Category 1 tropical cyclone on the Australian region scale on February 26. The system quickly intensified, reaching Category 4 status later that day. On the next day, Percy was steered southward by a blocking ridge of high pressure, while stretched out the structure of the storm into an elliptical shape, weakening it back to Category 3 status. Afterward, the storm rapidly reintensified, reaching its peak intensity as a Category 5 tropical cyclone on March 2. Afterward, Percy encountered increasing wind shear and weakened once again, turning southeastward on the next day. On March 5, Percy transitioned into an extratropical storm, before dissipating soon afterward.

2005–06 South Pacific cyclone season Tropical cyclone season

The 2005–06 South Pacific cyclone season was an event in the annual cycle of tropical cyclone formation. It began on November 1, 2005 and ended on April 30, 2006. These dates conventionally delimit the period of each year when most tropical cyclones form in the southern Pacific Ocean east of 160°E. Additionally, the regional tropical cyclone operational plan defines a tropical cyclone year separately from a tropical cyclone season, and the "tropical cyclone year" runs from July 1, 2005 to June 30, 2006.

Cyclone Urmil

Tropical Cyclone Urmil was a short lived storm of January 2006 that explosively intensified to reach its peak intensity as a high-end Category 2 cyclone on the Australian Scale, just 12 hours after being named. Forming out of a tropical disturbance early on January 14, Urmil quickly intensified before weakening just as quickly. The intensification was a result of the main convective banding feature wrapping around the center of circulation. However, the combination of high wind shear and the rapid movement of the cyclone caused convection to become separated from the center. By January 15, the storm transitioned into an extratropical cyclone shortly before dissipating. Urmil had only minor effects on land; scattered vegetation damage was reported in Tonga.

Cyclone Tam

Tropical Cyclone Tam was the first named storm of the 2005–06 South Pacific cyclone season. Forming out of a tropical depression on January 6, the storm gradually intensified, becoming a tropical cyclone on January 12 and receiving the name Tam. Although it was traveling at a quick pace, the storm gained organization and reached its peak intensity with winds of 85 km/h (50 mph) the following day. However, the increasing forward motion of the storm, combined with strengthening wind shear, caused Tam to rapidly weaken on January 14. Around that time, it entered the Tropical Cyclone Warning Centre in Wellington, New Zealand's area of responsibility. Shortly thereafter, the storm transitioned into an extratropical cyclone and dissipated early the next day. Cyclone Tam produced heavy rainfall and strong winds over American Samoa upon being named. The precipitation caused several mudslides and flooding, which inflicted $26,000 in damage. The storm also had minor effects on Niue, Tonga, and Futuna.

Cyclone Cilla Category 1 South Pacific cyclone in 2003

Tropical Cyclone Cilla was a tropical cyclone that brought minor damage to several islands in the South Pacific in January 2003. The fifth cyclone of the 2002–03 South Pacific cyclone season, Cyclone Cilla developed from a monsoon trough on January 26 northwest of Fiji. Initially, Cilla moved east, and due to decreased wind shear, Cilla was able to intensify. On January 28, Cilla reached its peak intensity of 75 km/h (45 mph). After slightly weakening, Cilla briefly re-intensified the next day. However, Cilla transitioned into an extratropical cyclone on January 30. Along its path, Cilla dropped heavy rainfall over islands it passed. During its formative stages, the low dropped heavy rain over Fiji, which had already been affected by Cyclone Ami two weeks prior. Damage in Tonga was mostly limited to vegetation and fruit trees; infrastructural damage was also relatively minor. Cilla also brought moderate rain to American Samoa.

Cyclone Waka Category 4 South Pacific cyclone in 2001 and 2002

Severe Tropical Cyclone Waka was one of the most destructive tropical cyclones ever to affect the South Pacific Kingdom of Tonga. Waka originated within the near-equatorial trough in mid-December 2001, although the system remained disorganized for more than a week. The storm gradually matured and attained tropical cyclone status on December 29. Subsequently, Waka underwent rapid intensification in which it attained its peak intensity as a Category 4 severe tropical cyclone on December 31, with winds of 185 km/h (115 mph). Shortly thereafter, it passed directly over Vavaʻu, Tonga, resulting in widespread damage. By January 1, 2002, the cyclone began to weaken as it underwent an extratropical transition. The remnants of Waka persisted for several more days and were last observed near the Southern Ocean on January 6.

Cyclone Val

Severe Tropical Cyclone Val was considered to be the worst tropical cyclone to affect the Samoan Islands since the 1889 Apia cyclone.

Cyclone Wilma

Severe Tropical Cyclone Wilma was a powerful tropical cyclone that affected the Samoan Islands, Tonga and New Zealand. Forming out of a trough of low pressure on 19 January 2011 to the northwest of Fiji, Cyclone Wilma initially tracked eastward towards the Samoan Islands. On 22 January, the system took a sharp southward turn, bringing its centre directly over American Samoa the following day. After turning towards the southwest and accelerating, Wilma steadily intensified into a severe tropical cyclone before striking Tonga. The storm reached its peak intensity on 26 January as a Category 4 cyclone with winds of 185 km/h (115 mph) and a barometric pressure of 930 mbar. Gradually re-curving towards the southeast, Wilma weakened quickly as it moved over cooler sea surface temperatures; by 28 January, it was downgraded to a tropical cyclone. Later that day, the storm brushed the North Island of New Zealand before transitioning into an extratropical cyclone.

Cyclone Ofa

Severe Tropical Cyclone Ofa was considered to be the worst tropical cyclone to affect Polynesia since Cyclone Bebe. The system was first noted on January 27, 1990, near Tuvalu, as a shallow tropical depression that had developed within the South Pacific Convergence Zone. The cloud pattern slowly organized, and on January 31, while located east of Tuvalu, Ofa attained cyclone intensity. Moving slowly southeast, Ofa developed storm-force winds. It attained hurricane-force winds on February 2. Cyclone Ofa reached peak intensity on February 4. Shortly after, its peak Ofa began to weaken over a less favourable environment. Ofa was declared an extratropical cyclone on February 8, though the system was still tracked by meteorologists until February 10.

Cyclone Evan

Severe Tropical Cyclone Evan was considered to be the worst tropical cyclone to affect the island nation of Samoa since Cyclone Val in 1991 and was formerly the strongest storm to impact the main islands until Winston in 2016. The system was first noted on December 9, 2012, as a weak tropical depression about 700 km (435 mi) to the northeast of Suva, Fiji. Over the next couple of days the depression gradually developed further before it was named Evan on December 12, as it had developed into a tropical cyclone. During that day the system moved toward the Samoan Islands and gradually intensified, before the system slowed and severely affected the Samoan Islands during the next day with wind gusts of up to 210 km/h (130 mph).

2017–18 South Pacific cyclone season Tropical cyclone season

The 2017–18 South Pacific cyclone season was a slightly below-average season that produced 6 tropical cyclones, 3 of which became severe tropical cyclones. The season officially began on November 1, 2017, and ended on April 30, 2018; however, a tropical cyclone could form at any time between July 1, 2017, and June 30, 2018, and would count towards the season total. During the season, tropical cyclones were officially monitored by the Fiji Meteorological Service, MetService and the Australian Bureau of Meteorology, while the United States Joint Typhoon Warning Center (JTWC) also monitored the basin and issued warnings for American interests. The FMS attaches a number and an F suffix to significant tropical disturbances that form in or move into the basin, while the JTWC designates significant tropical cyclones with a number and a P suffix. The BoM, FMS and MetService all use the Australian Tropical Cyclone Intensity Scale and estimate wind speeds over a period of ten minutes, while the JTWC estimates sustained winds over a 1-minute period, which are subsequently compared to the Saffir–Simpson hurricane wind scale (SSHWS).

2019–20 South Pacific cyclone season Tropical cyclone season

The 2019–20 South Pacific cyclone season was a slightly above-average season in which tropical cyclones formed within the South Pacific Ocean to the east of 160°E. The season officially ran from November 1, 2019 to April 30, 2020, however a tropical cyclone could form at any time between July 1, 2019 and June 30, 2020 and would count towards the season total. The season began on November 22 with the formation of Tropical Cyclone Rita, which would later become a severe tropical cyclone. The season has been near-average in terms of activity, with 8 tropical cyclones and 4 severe tropical cyclones forming during the season. The season featured Cyclone Harold, the first Category 5 severe tropical cyclone in the basin since Cyclone Gita, and one of the strongest since Cyclone Winston. During the season, tropical cyclones are officially monitored by the Fiji Meteorological Service (FMS), Australian Bureau of Meteorology (BOM) and New Zealand's MetService. The United States Armed Forces through the Joint Typhoon Warning Center (JTWC) also monitors the basin and issue unofficial warnings for American interests. The FMS attaches a number and an F suffix to tropical disturbances that form in or move into the basin while the JTWC designates significant tropical cyclones with a number and a P suffix. The FMS, BoM and MetService all use the Australian Tropical Cyclone Intensity Scale and estimate wind speeds over a period of ten minutes, while the JTWC estimated sustained winds over a 1-minute period, which are subsequently compared to the Saffir–Simpson hurricane wind scale (SSHWS)

Cyclone Tusi

Severe Tropical Cyclone Tusi was a tropical cyclone which affected the island nations of Tuvalu, Tokelau, Western Samoa, American Samoa, Niue and the Southern Cook Islands during January 1987. The precursor tropical depression to Cyclone Tusi developed on January 13, 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 (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 during January 20.

Cyclone Ula

Severe Tropical Cyclone Ula was a powerful and long-lived tropical cyclone during late December 2015 and mid-January 2016. It originated from a tropical disturbance on December 26, 2015, east of the Solomon Islands. Moving generally east, development was initially slow and the system finally reached cyclone strength—having gale-force winds—on December 30. The newly christened Tropical Cyclone Ula turned sharply south and rapidly intensified, attaining hurricane-strength the following day. A shift to the southwest brought the system close to the northern islands of Tonga on January 2, 2016. It subsequently brushed several islands in the Lau Group of Fiji before weakening. Nearly degrading to a tropical depression, Ula turned to the northwest and regained strength. After turning back to the southwest, it achieved its peak intensity as a Category 4 on the Australian scale with winds of 185 km/h (115 mph) on January 10. Thereafter, the storm bypassed Vanuatu to the southeast and New Caledonia to the east as it accelerated southward.

Cyclone Meena 2005 tropical cyclone

Severe Tropical Cyclone Meena was the first of four tropical cyclones to impact the Cook Islands during February 2005. The system was first identified within a trough of low pressure, about 620 km (385 mi) to the northwest of Pago Pago in American Samoa.

Cyclone Amos

Severe Tropical Cyclone Amos was a strong tropical cyclone that affected the Fijian and Samoan Islands as well as Wallis and Futuna. Amos was first noted as Tropical Disturbance 17F during April 13, 2016 to the northwest of Fiji. The system subsequently moved south-eastwards towards the Fijian Islands, before it passed near or over Vanua Levu during April 16. After passing over Fiji, the system gradually developed further as it moved north-eastwards towards the Samoan Islands. The system was subsequently named Amos during April 20, after it had developed into a tropical cyclone and started to move north-westwards towards the island nation of Tuvalu.

The following is a list of all reported tropical cyclones within the South Pacific Ocean to the east of 160°E after the start of World War II in September 1939 and before the start of the 1950s decade.

Cyclone Tino Category 3 South Pacific cyclone of 2020

Severe Tropical Cyclone Tino was a tropical cyclone which itself and an associated convergence zone caused significant damage across ten island nations in the South Pacific Ocean during January 2020. First noted as a tropical disturbance during January 11, to the southwest of Honiara in the Solomon Islands, the system gradually developed over the next few days as it moved eastwards in between the Solomon Islands and Vanuatu prior to being named Tino as it approached Fiji during January 16. Continuing to track south-eastward, Tino continued strengthening as it passed near Fiji, bringing copious amounts of rainfall to the area. Whilst losing latitude, the system continued to strengthen and peaked as a category 3 tropical cyclone on January 17, with signs of an eye forming. Shortly after peak intensity, Tino was impacted by high wind shear and decreasing sea surface temperatures, triggering a weakening trend. Tino moved out of the tropics shortly thereafter and became an extratropical cyclone during January 19.
