The 1994–95 South Pacific cyclone season was one of the least active South Pacific tropical cyclone season on record, with only four tropical cyclones officially occurring within the South Pacific Ocean basin between 160°E and 120°W. The season ran from November 1, 1994, until April 30, 1995, with the first disturbance of the season developing on November 12 and the last disturbance leaving the base on March 5. The most intense tropical cyclone during the season was Tropical Cyclone Violet, which briefly existed within the basin. After the season the name William was retired from the tropical cyclone naming lists.

During the season, tropical cyclones were officially monitored by the Fiji Meteorological Service, New Zealand's MetService and Australia's Bureau of Meteorology. Throughout the season the United States Navy also monitored the basin and issued unofficial warnings, through its Joint Typhoon Warning Center (JTWC) and Naval Pacific Meteorology and Oceanography Center (NPMOC). Tropical cyclones that were located between the Equator and 25S were monitored by the FMS while any that were located to the south of 25S were monitored by MetService. During the season the JTWC issued warnings on any tropical cyclone that was located between 160°E and 180° while the NPMOC issued warnings for tropical cyclones forming between 180° and the American coast. The FMS, MetService and BoM all used the Australian Tropical Cyclone Intensity Scale, and measured windspeeds over a 10-minute period, while the JTWC and the NPMOC measured sustained windspeeds over a 1-minute period.

The season was one of the most inactive tropical cyclone seasons on record, with only four tropical cyclones officially occurring within the South Pacific Ocean basin between 160°E and 120°W.[1][2] The first tropical depression of the season developed out of an area of convection on November 12 to the northeast of Vanuatu, before it was named Vania on November 14 after it had become a category 1 tropical cyclone.[1] The cyclone went on to end a long dry spell in Vanuatu, before it last noted on November 19 to the west of Port Vila, Vanuatu. The basin remained quiet until December 13, when Tropical Depression 04P developed to the east of the Solomon Islands, before going on to affect Fiji and Tonga.[3] During the final days of 1994, several areas of low pressure developed, within the South Pacific Convergence Zone between 8°S and 16°S, and 180°W and 160°W. During December 30, one of these areas of low pressure developed into a tropical depression, within the northern Cook Islands just to the east of Pukapuka atoll.[4] Over the next couple of days, the depression moved southeastwards towards the Southern Cook Islands and gradually developed into Tropical Cyclone William.[5] Throughout its lifetime, William moved southeast and affected parts of French Polynesia and the Cook Islands before becoming extratropical on January 3.[6] After William left the basin on January 5, the basin remained quiet until March 6, when Severe Tropical Cyclone Violet briefly crossed into MetService's area, before crossing back to the BoM's area hours later.[2]

After the season had ended, the name William was retired from the tropical cyclone naming lists, due to its destruction. In 1995, the World Meteorological Organization would designste the FMS as a Regional Specialized Meteorological Center.Шаблон:RA V Tropical cyclone operational plan

Systems

Tropical Cyclone Vania

Шаблон:Infobox Hurricane Small A persistent cloud mass east of the Solomon Islands evolved into a tropical depression on November 12, according to the FMS.[7][5] Located about Шаблон:Convert northeast of Tikopia, the system had gale-force winds developing on its southern side.[7][8] The depression moved south-eastwards at first, before it turned southwestwards through Temotu Province towards Vanuatu, which prompted the FMS to start issuing special weather bulletins for the island nation during November 13.[7][8][9] Later that day, the JTWC initiated advisories, designating it Tropical Cyclone 01P. On November 14, the FMS named the system Vania, after it had become a category 1 tropical cyclone on the Australian scale.[7][8][10] Intensifying further, Vania moved through northern Vanuatu on November 15 as a category 2 tropical cyclone.[8] Later that day, the FMS predicted that Vania would become a hurricane and issued a hurricane warning; however, Vania had peaked as a category 2 tropical cyclone with peak 10-minute sustained windspeeds of between Шаблон:Convert, while the JTWC estimated that the system had peaked with 1-minute sustained windspeeds of Шаблон:Convert.[8][10] [7] Over the next couple of days, the system stalled and started to move westwards, before the FMS and JTWC issued their final advisories on the cyclone during November 18, as it had weakened below tropical cyclone intensity and degenerated into a sheared depression to the north of New Caledonia.[7][8][10] The remnant low-level circulation was last noted during November 19, while they were located about Шаблон:Convert to the west of Port Vila.[8]

Within Vanuatu, preparations had been completed for a storm-force cyclone, before the FMS issued a hurricane warning at 18:15 VUT (07:15 UTC) on November 15, which prompted a higher response from the residents of the island nation.[7] The warning proved problematic as it was issued just after it had gone dark, which caused the higher response to be done in darkness when the winds were becoming stronger which endangered residents.[7] It was later realised that the hurricane warning should not have been issued, as only storm-force winds were experienced over Vanuatu, while various weather stations reported winds below Шаблон:Convert.[7] Overall the system had a minimal impact on the island nation with damage reported to crops and bush houses, while heavy rain associated with the cyclone helped break a long dry spell of weather in Vanuatu.[5] Vania also brought rain to parts of Fiji which were responsible for severe flooding within Tailevu Province, which in turn caused over Шаблон:Convert of crops to be damaged and the deaths of a significant amount of farm animals.[7][11][12]

Tropical Cyclone 04P

Шаблон:Infobox Hurricane Small

During December 13, a tropical depression developed about Шаблон:Convert to the northeast of Suva, Fiji.[13] The system subsequently moved south-eastwards towards Fiji and gradually developed further, before the NPMOC designated the system as Tropical Cyclone 04P and initiated advisories on the depression during December 15.[13][10] At this time, the system was located about Шаблон:Convert to the northeast of Labasa, Fiji and was estimated to have maximum 1-minute sustained wind-speeds of Шаблон:Convert.[3] Over the next couple of days, the system passed through Fiji's Lau Islands and Tonga's Haʻapai Group of islands, before system was declared extratropical as it moved below 25S and into MetService's area of responsibility.[3][13] Within Fiji, there were no report of any casualties, damage or gale-force winds associated with the system, however, several pressures of between Шаблон:Convert were reported.[13]

Tropical Cyclone William

Шаблон:Infobox Hurricane Small On December 30, The FMS reported that a tropical depression had developed about Шаблон:Convert, to the northeast of Pago Pago in American Samoa.[14] Over the next couple of days the system moved towards the south-southeast and gradually developed further, before the NPMOC designated the depression as Tropical Cyclone 05P.[10][6] During January 1, TCWC Nadi reported that the depression had developed into a category 1 tropical cyclone and named it William as it passed near the Cook Island of Autitaki.[6] During the next day William subsequently slowly accelerated as it passed near too or over several other Cook Islands and intensified into a category 2 tropical cyclone.[6]

During January 3, the system passed near or over the French Polynesian islands of Maria and Rimatara, where sustained winds of Шаблон:Convert and wind gusts of up to Шаблон:Convert were recorded.[15] Later that day, both the NPMOC and the FMS estimated that the system had peaked just below hurricane-force with winds of Шаблон:Convert, as it left the tropics and transitioned into an extratropical cyclone.[14][6] William's extratropical remnants were tracked by MetService for another couple of days as they moved south-eastwards in the westerlies, before they were last noted near 40.0S 119.5E during January 5, as they moved out of the South Pacific basin.[14] Throughout the Southern Cook Islands caused around Шаблон:Ntsp worth of damage to crops, buildings and coconut trees and destroyed a causeway to a tourist resort on Aitutaki.[5][4] William injured two people and destroyed over 150 houses in French Polynesia, where local leaders accused Météo-France off underestimating Williams intensity.[16]

Severe Tropical Cyclone Violet

Шаблон:Infobox Hurricane Small

On March 5, Severe Tropical Cyclone Violet peaked as a category 3 severe tropical cyclone, as it moved south-eastwards and moved into the South Pacific basin, inside MetService's area south of 25S, before it recurved south-westwards and moved out of the basin later on the same day.[2][17]

Other systems

Tropical Depression 18P

Шаблон:Infobox Hurricane Small

The system that would become Tropical Cyclone 18P was first noted during March 15, while it was located about Шаблон:Convert to the northeast of Nadi, Fiji.[18] Over the next couple of days, the system moved south-eastwards away from Fiji and was classified as Tropical Cyclone 18P by the NPMOC during March 16, while it was located about Шаблон:Convert to the south-east of Nuku'alofa in Tonga.[10][19] At this time, the system was estimated by the NPMOC, to have maximum 1-minute sustained wind-speeds of Шаблон:Convert.[18] The system subsequently dissipated during the following day, while it was located within MetService's area of responsibility well to the northeast of Wellington, New Zealand.[19] While 18P existed over the South Pacific, a trough of low pressure impacted Fiji, which caused moderate to heavy rain and flooding to be reported in Labasa and Nadi, while over 250 tonnes of canne were destroyed.[12]

Season effects

This table lists all the storms that developed in the South Pacific basin during the 1994–95 season. It includes their intensity on the Australian Tropical cyclone intensity scale, duration, name, areas affected, deaths, and damages. For most storms the data is taken from TCWC Nadi and Wellington's archives, however data for 04P have been taken from the JTWC archives as opposed to TCWC Nadi and Wellington's, and thus the winds are over 1-minute as opposed to 10-minutes.
