Severe Tropical Cyclone Nina was a significant tropical cyclone which impacted six island nations from December 1992 to January 1993. The system was first noted as a tropical low over the Cape York Peninsula on 21 December. Over the next few days the system moved south-westwards and moved into the Gulf of Carpentaria where it was named Nina,after it had developed into a tropical cyclone during 23 December. The system was subsequently steered south-eastwards by an upper level trough of low pressure,before it made landfall as a Category 2 tropical cyclone on the Cape York Peninsula near Cape Keerweer on 25 December. Over land the system weakened into a tropical low before it regenerated into a tropical cyclone over the Coral Sea on 28 December. The system subsequently moved north-eastwards,under the influence of Severe Tropical Cyclone Kina and an upper level ridge of high pressure. During 1 January 1993,Nina peaked with sustained wind speeds of 140 km/h (85 mph),as it affected Rennell,Bellona and Temotu provinces in the Solomon Islands. The system subsequently gradually weakened as it accelerated eastwards and affected Rotuma,Wallis and Futuna,Tonga and Niue. Nina was subsequently absorbed by Kina,while both systems were located near the Southern Cook Islands during 5 January.
During the middle of December 1992, an active phase of the Madden–Julian oscillation took place which helped to reinforce atmospheric convection across Northern Australia and the western Pacific Ocean. [1] A tropical low subsequently developed within this area of atmospheric convection and moved south-westwards into the warm waters of the Gulf of Carpentaria during 22 December. [2] [3] During the following day, the United States Joint Typhoon Warning Center initiated advisories on the low and designated it as Tropical Cyclone 03P before the Australian Bureau of Meteorology named the system: Nina, after it had developed into a Category 1 tropical cyclone on the Australian tropical cyclone intensity scale. [4] [5]
Over the next day the system continued to intensify before both the JTWC and the BoM reported that Nina had peaked with winds of 100 km/h (65 mph) during 25 December, which made it a category 2 tropical cyclone on the Australian scale. [2] The system subsequently made landfall on the Cape York Peninsula during that day near Cape Keerweer, where it weakened into a tropical low and emerged into the Coral Sea on 27 December. [1] [2] [6]
The system re-intensified into a tropical cyclone during 28 December, as it moved north-eastwards, under the influence of Severe Tropical Cyclone Kina and an upper level ridge of high pressure. [1] Over the next few days, the system continued to re-intensify as it moved north-eastwards, before both the JTWC and the BoM reported that Nina had peaked with winds of 140 km/h (85 mph). [1] [2] This made it a Category 3 severe tropical cyclone on the Australian scale and equivalent to a category 1 hurricane on the Saffir–Simpson hurricane wind scale. [2] [7] On 1 January, Nina passed over Rennell Island at its peak intensity, as it moved into the South Pacific basin. [5] [7] Over the next few days, the system gradually weakened, as it accelerated eastwards through Temotu Province and around the eastern side of Kina. [5] [2] [8] During 3 January, Nina passed to the north of the Fijian dependency of Rotuma, before it passed in between the islands of Wallis and Futuna. [5] During the next day the system weakened into a tropical low, as it turned south-eastwards and passed in between Tonga and Niue, before it was absorbed into Kina's circulation, while both systems were located near the Southern Cook Islands during 5 January. [5] [2]
Severe Tropical Cyclone Nina impacted the Gulf of Carpentaria, the Cape York Peninsula, Niue, Rotuma, Tonga, Tuvalu, the Solomon Islands, Wallis and Futuna. [5] Due to the impact of this system, the name Nina was subsequently retired, from the list of names for the Australian region by the World Meteorological Organization. [9]
As Nina developed in the Gulf of Carpentaria, tropical cyclone watches and warnings were issued, for parts of the Northern Territory and Queensland. [10] These areas included Nhulunbuy in the Northern Territory, Mapoon, Aurukun and the Lockhart River in Queensland. [10] [11] The system subsequently moved eastwards and affected sparsely populated and uninhabited areas of the Cape York Peninsula, where torrential rainfall was recorded on 25 December. [12] As a result of Nina impacting Queensland, the State Disaster Coordination Centre in Brisbane operated around the clock, while SES units, local authorities and disaster district coordinators in the region were put on full alert. [13] [14] Ahead of the system affecting Port Stewart, ten members of a twenty-member fishing party were evacuated to safety while the other ten refused to be evacuated. [11] As a result, they were left stranded at the port, by the swollen Stewart River and its flooded tributaries until a rescue helicopter rescued them. [11] [15] Within the Aurukun Aboriginal community and Pormpuraaw widespread damage to trees were reported, while four houses were damaged by flying tree branches. [6] [16]
After impacting Queensland, Nina impacted the Solomon Islands between 30 December and 3 January, where it caused extensive damage to southern and eastern islands including Rennell and Bellona. [8] [17] Islanders were caught almost unprepared for Nina, because of preparations for the traditional New Year Celebrations. [5] There were 3 people killed in the islands with an elderly woman killed on Bellona after she was trapped under a collapsed house while twins born at the height also died from lack of warm dry linen and shelter. [5] The only buildings left standing were the Australian built Seventh Day Adventist churches in these islands. [5]
The Solomon Islands Government declared parts of Rennell and Bellona, Southern Guadalcanal, Temotu, Makira and Malaita Provinces disaster areas. [8] The Government subsequently shipped and airlifted relief materials to the affected areas, including food supplies, medical supplies, tarpaulins and water. [8] The Solomon Islands Red Cross also helped with the relief effort and dispatched 113 tarpaulins to four provinces to shelter the homeless, along with blankets, clothing and various household items. [8] They used reserve funds in order to transport these supplies to the islands affected by canoe and plane. [8] The Government of the Solomon Islands subsequently launched an appeal for international assistance, with food assistance, tarpaulins, tents, water containers and chainsaws amongst the things asked for. [8] A need also existed for helicopters and aircraft services, in order for field assessments to take place and the transportation of water engineers. [8]
Ahead of the system affecting Rotuma, a storm force wind warning was issued for Rotuma, with sustained wind speeds of 95 km/h (60 mph) and wind gusts of up to 140 km/h (85 mph) were forecast to occur. [5] However, the system only had a minimal effect on Rotuma, with a few rain showers and sustained winds of 45 km/h (30 mph) occurring for a brief period. [5] In conjunction with Kina, Nina affected Wallis and Futuna between 3–4 January, however, there were no tropical cyclone warnings were issued for the French Territory by the FMS. [5] [18] Kina affected the island of Futuna during 3 January, where sustained winds of up to 53 km/h (33 mph) and wind gusts of up to 69 km/h (43 mph) were recorded. [5] Nina affected Wallis Island later that day where sustained winds of up to 80 km/h (50 mph) and wind gusts of up to 68 km/h (42 mph) were recorded. [18] [19] Within the islands some damage to crops and houses was reported. [5]
Ahead of Nina affecting the Samoan Islands, residents living near the sea were warned to move inland, while ships were ordered to remain in port. [20] The system subsequently passed to the south of the Samoan Islands during 4 January, where it brought high winds and caused wind gusts of 95 km/h (60 mph) at Pago Pago in American Samoa. [21] [22] Some minor damage to roofs, bananas and breadfruit was reported, while total damages in American Samoa to both property and crops were estimated at between $50,000 and $500,000. [21]
Nina affected Northern Tonga on 4 January, just after Kina had affected Tonga's southern islands with hurricane-force winds. [5] [23] Ahead of Nina affecting the islands, a gale warning was issued for the islands of Niuafo'ou and Keppel, where some damage to houses and crops were recorded. [5] A gale warning was also issued for the island nation of Niue on the same day (4 January), where winds of up to 75 km/h (45 mph) caused damage to the island nations port. [5]
After Severe Tropical Cyclone Joni had affected Tuvalu during the previous month, Nina and Kina indirectly impacted the island nation during the opening days of January 1993. [5] [24] [25] The systems contributed to the strength of the westerly winds that were already present over the islands, with winds of up to 130 km/h (80 mph) reported throughout the islands. [5] [24] As these winds combined with a heavy westerly swell and high seas, where they caused flooding of up to 2 ft (0.61 m) over the islands of Nanumea, Nanumaga, Niutao, Nui and Vaitupu. [5] [26] As a result, damage was reported to crops and several buildings in the island nation, including thirty houses. [24] [27] The two cyclones caused a severe amount of erosion in the island nation, with the shoreline on Vaitupu, receding by about 5–6 m (16–20 ft). [25] The Vaitupu Fisheries Harbour, that had only just been built during 1992, was seriously damaged by waves attributed to the two cyclones. [28]
On the island of Nanumea, a poorly designed sea wall trapped the storm surge on the island, which caused salt water contamination of the island vegetation and killed several trees. [26] An appeal for international assistance was subsequently made by the Government of Tuvalu, as supplies of food and other essentials like petrol and kerosene on the worst affected islands were running low. [24] International assistance was subsequently provided, by the United Nations Department of Humanitarian Affairs, who provided an emergency grant of US$10,000. [29] The European Commission also provided emergency aid to Tuvalu which enabled the Red Cross, to provide foodstuffs, shelter, medical supplies and utensils to people whose homes were destroyed. [30]
Severe Tropical Cyclone Zoe was the second-most intense tropical cyclone on record within the Southern Hemisphere and was the strongest tropical cyclone worldwide in 2002. The system was first noted on December 23, 2002, as a tropical depression that had developed, within the South Pacific Convergence Zone to the east of Tuvalu. Over the next couple of days, the system moved southwestwards and crossed the International Dateline early on December 25. After this, the system became better organized and was declared to be a tropical cyclone and named Zoe later that day. Zoe subsequently rapidly intensified in very favorable conditions as it continued to move west-southwest towards the Solomon Islands. The system subsequently became a Category 5 tropical cyclone on both the Australian tropical cyclone intensity scale and the Saffir-Simpson hurricane wind scale on December 27. The system subsequently affected the Solomon Islands Temotu Province during that day, before it peaked with 10-minute sustained wind speeds of 240 km/h (150 mph). As the system peaked, it performed a small clockwise cyclonic loop within the vicinity of Tikopia island, as a result of the steering flow over the cyclone becoming weak and variable. The system subsequently started to move towards the southeast during December 29, in response to a strengthening steering flow, provided by an upper level trough of low pressure and a baroclinic system near New Caledonia. Over the next few days the system weakened and degenerated into a tropical depression during January 1, 2003. The system was subsequently last noted during January 4, while it was located to the southeast of New Caledonia.
The 1992–93 South Pacific cyclone season was an above-average tropical cyclone season with ten tropical cyclones occurring within the South Pacific to the east of 160°E. The season officially ran from November 1, 1992, to April 30, 1993, with the first disturbance of the season forming on December 3 and the last disturbance dissipating on April 6.
The 1987–88 South Pacific cyclone season was a quiet tropical cyclone season with five tropical cyclones and 2 severe tropical cyclones, observed within the South Pacific basin to the east of 160°E.
The 1996–97 South Pacific cyclone season was one of the most active and longest South Pacific tropical cyclone seasons on record, with 12 tropical cyclones occurring within the South Pacific basin between 160°E and 120°W. The season officially ran from November 1, 1996 - April 30, 1997, however, the season ended later than normal with three systems monitored after the official end of the season. The strongest tropical cyclone of the season was Cyclone Gavin which had a minimum pressure of 925 hPa (27.32 inHg). After the season had ended 4 tropical cyclone names were retired from the naming lists, after the cyclones had caused significant impacts to South Pacific islands.
Severe Tropical Cyclone Keli was the first recorded post-season tropical cyclone to form in June within the South Pacific Ocean. The system formed on June 7, 1997, about 460 kilometers (285 mi) to the north of Tokelau. The depression gradually developed over the next few days while moving southwestward. It was designated as Tropical Cyclone Keli early the next day. Cyclone Keli intensified, slowly reaching its 10-minute peak wind speeds of 150 km/h (90 mph), which made it a Category 3 severe tropical cyclone on the Australian Tropical Cyclone Intensity Scale. As it came under the influence of strong mid latitude westerlies and moved into an area of strong vertical wind shear, the cyclone started to weaken and was declared extratropical on June 15.
The 1991–92 South Pacific cyclone season was an above average tropical cyclone season, with eleven tropical cyclones occurring within the South Pacific basin between 160°E and 120°W. The first tropical cyclone of the season was first noted on November 13, 1991, while the last tropical cyclone dissipated on May 2, 1992. During the season at least 21 people were killed by tropical cyclones, while Tropical Cyclones Cliff and Innis were the only tropical cyclones not to cause any damage to any country in the Southern Pacific.
Severe Tropical Cyclone Val was considered to be the worst tropical cyclone to affect the Samoan Islands since the 1889 Apia cyclone. The system was first identified during the opening days of December 1991, as a small circulation, within the Intertropical Convergence Zone to the north of Tokelau. Over the next few days, the system moved westwards towards Rotuma and Tuvalu and gradually developed further, before it was named Val on December 5, after it had become a category 1 tropical cyclone on the Australian tropical cyclone intensity scale. The system subsequently continued to intensify as it moved towards the Samoan Islands and peaked as a category 4 severe tropical cyclone, as it made landfall on the island of Savaii on December 6. After Val had passed over the island, weakening upper-level winds caused the system to slow down before it made a sharp clockwise loop which almost brought it over Savaii for a second time.
The 1982–83 South Pacific cyclone season was one of the most active and longest South Pacific tropical cyclone seasons on record, with 16 tropical cyclones occurring within the South Pacific basin between 160°E and 120°W. During the season tropical cyclones were monitored by the meteorological services of Australia, Fiji, French Polynesia and New Zealand. The United States Armed Forces through the Joint Typhoon Warning Center (JTWC) and Naval Pacific Meteorology and Oceanography Center (NPMOC), also monitored the basin and issued unofficial warnings for American interests. The first tropical cyclone of the season developed a day before the season officially began on October 30, while the last tropical cyclone of the season dissipated on May 16. Most of the activity during the season occurred within the central and eastern parts of the basin with French Polynesia affected by several systems.
Severe Tropical Cyclone Joni was a damaging tropical cyclone that impacted the island nations of Tuvalu and Fiji. It was first noted within the South Pacific Convergence Zone at the start of December 1992, as a shallow tropical depression in the vicinity of the island nation Tuvalu. Over the next few days the system gradually developed further as it affected Tuvalu, before it was declared to be a tropical cyclone and named Joni by the Fiji Meteorological Service (FMS) during December 7. Over the next couple of days the system intensified further as it was steered south-westwards and posed a threat towards the Fijian dependency of Rotuma and the French territory of Wallis and Futuna. The system subsequently peaked as a Category 4 severe tropical cyclone on the Australian tropical cyclone intensity scale as it approached the Fijian Islands during December 10. Over the next couple of days the system moved through the Fijian Islands, before it became an extratropical cyclone during December 13. The system was last noted during the next day as it was absorbed by a mid-latitude trough of low pressure to the east of New Zealand.
Severe Tropical Cyclone Kina was at the time the costliest storm to impact Fiji on record. Total losses from Kina are estimated to be near $F170 million ($US110 million). The system was first noted as a tropical depression, to the east of the Solomon Islands on 23 December. Over the next few days the system moved south-eastwards and gradually developed further, before it was named Kina, after it had developed into a tropical cyclone on 26 December.
The 2016–17 South Pacific cyclone season was the least active South Pacific cyclone season since the 2011–12 season, with only four tropical cyclones occurring within the South Pacific Ocean to the east of 160°E. Two of the four systems developed into severe tropical cyclones on the Australian tropical cyclone intensity scale. The season officially ran from November 1, 2016 until April 30, 2017. However, May featured two post-season systems: Donna and Ella, of which the former was the strongest post-season South Pacific tropical cyclone ever recorded in that month. Overall, 22 tropical disturbances were monitored by a combination of the Fiji Meteorological Service (FMS), Australian Bureau of Meteorology (BoM) and New Zealand's MetService.
The 2018–19 South Pacific cyclone season was a below-average season that produced 5 tropical cyclones, 2 of which became severe tropical cyclones. The season officially runs from November 1, 2018, to April 30, 2019; however, a tropical cyclone could have formed at any time between July 1, 2018, and June 30, 2019, and would count towards the season total. During the season, tropical cyclones were officially monitored by the Fiji Meteorological Service, Australian Bureau of Meteorology, and New Zealand's MetService. The United States Armed Forces through the Joint Typhoon Warning Center (JTWC) also monitored the basin and issued warnings for American interests. RSMC Nadi 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, the BoM 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).
Severe Tropical Cyclone Gavin was the most intense tropical cyclone to affect Fiji, since Cyclone Oscar of the 1982–83 cyclone season and was the first of three tropical cyclones to affect the island nations of Tuvalu and Wallis and Futuna during the 1996–97 season. The system that was to become Gavin was first identified during March 2, as a weak tropical depression that had developed within the monsoon trough of low pressure. Over the next two days the depression gradually developed further, before it was named Gavin by RSMC Nadi early on March 4 as it had developed into a tropical cyclone.
Severe Tropical Cyclone Hina in March 1997 was the worst tropical cyclone to affect the South Pacific island nation of Tonga since Cyclone Isaac in 1982. The system was first noted within the monsoon trough on March 11, 1997, as a weak shallow depression within the vicinity of Rotuma. Over the next two days, the depression remained near Rotuma with no preferred movement, as it started to develop further within favorable conditions for further development. The system was subsequently named Hina on March 15, after it had started to move eastwards and had passed to the southeast of Niulakita, Tuvalu. During that day the system moved south-eastwards and impacted Wallis and Futuna, before it passed over Tonga's southern islands of Tongatapu and 'Eua during March 16. After impacting Tonga the system moved rapidly towards the south-southeast and weakened below tropical cyclone intensity, before it was last noted on March 21 about 1,500 km (930 mi) to the south of the Pitcairn Islands. During the system's post-analysis, it was determined that the warning centers had underestimated Hina's intensity as it passed over Tonga, after damage in the island nation had been greater than expected.
Severe Tropical Cyclone Betsy was a strong and long-lived tropical cyclone which impacted 8 island nations.
Severe Tropical Cyclone Bebe, also known as Hurricane Bebe, was a pre-season storm during October 1972 in the South Pacific Ocean that severely affected Fiji, the Ellice Islands, and the Gilbert Islands.
Severe Tropical Cyclone Raja was a tropical cyclone that holds the 24-hour rainfall record of 674.9 mm (26.57 in) for the French Overseas Territory of Wallis and Futuna. The system was first noted by the Fiji Meteorological Service (FMS) as a weak tropical disturbance northeast of Tokelau in mid-December 1986. The system developed further as it moved southwest over the next few days, and it was classified as Tropical Cyclone Raja on 23 December. The newly named system slowed and unexpectedly recurved southeast towards the French territory of Wallis and Futuna on 24 December. Over the next two days, Raja interacted with what would become Severe Cyclone Sally and executed a tight loop, passing within 55 km (35 mi) of Futuna. The system peaked as a Category 3 severe tropical cyclone on 28 December, with estimated 10-minute sustained winds of 90 mph (150 km/h). The storm turned southwest the next day and threatened Fiji, where it passed within 20 km (10 mi) of Vanua Levu and near several smaller islands in the Lau group during the following day. Raja gradually weakened over the next few days as it moved south of Fiji; it was last noted on 5 January 1987 after it filled up over the north Tasman Sea.
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.
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.
