During February 13, a depression developed just to the north of the Marquesas Islands and started moving south-westwards. [5][6] After the system had moved into the Coral Sea, it gradually weakened and turned towards the south-southwest, before it degenerated into a depression during November 7. Mark existed from January 20 to February 1. *Spanish translations, when available, are courtesy of the NWS San Juan Weather Forecast Office. [18][19] Some minor damage to vegetation was reported in Niue, as a result of Tomasi.[18]. Keep betting pools off this page - there are separate forum pages for those. During that day, the system started to rapidly develop further as it moved and was named Rewa, as it had developed into a Category 1 tropical cyclone. [7] Deep convection near the system was initially only fragmented; however, environmental conditions were assessed as being conducive for development, with low vertical wind shear, good upper-level outflow and sea surface temperatures near 29 °C (84 °F). During March 7, a tropical depression developed about 650 km (405 mi) to the northeast of the Society Islands. The next 10 names on the naming list are listed here below.[32]. The South Pacific is in a cyclone zone that typically has cyclones between 1st November and 31st April each year. [5] After it was named, Joti continued to develop as it completed a cyclonic loop, before it started to move south-westwards towards Vanuatu during November 2. [17] The JTWC subsequently initiated advisories on the system and designated it as Tropical Cyclone 18P. It had no official bounds; it ran year-round in 1964, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. The 1997–98 South Pacific cyclone season was the most active South Pacific tropical cyclone season on record, with 16 tropical cyclones occurring within the South Pacific basin between 160°E and 120°W. [29] Zazu brought heavy surf which severely damaged the wharf on Niue which was recently rebuilt while bringing rainy conditions to the island that same day. 1982–83 South-West Indian Ocean cyclone season, List of off-season South Pacific tropical cyclones, http://dailypost.vu/news/developing-el-nino-predicted-stronger-than---dubbed-godzilla/article_fe5cafeb-3ac9-5da5-b17d-9c3f29359515.html, Tropical cyclones in Vanuatu: 1847 to 1994, "1983 Tropical Cyclone TOMASI (1983086S08204)", https://en.wikipedia.org/w/index.php?title=1982–83_South_Pacific_cyclone_season&oldid=979572574, Articles which contain graphical timelines, Creative Commons Attribution-ShareAlike License, Category 2 tropical cyclone (Australian scale), Category 1 tropical cyclone (Australian scale), Category 3 severe tropical cyclone (Australian scale), Category 4 severe tropical cyclone (Australian scale), This page was last edited on 21 September 2020, at 14:05. [9][10] The system caused strong winds and rough seas on Viti Levu and in the Yasawas and Mamanutha group of islands. Following the same day, another disturbance formed and intensified into a depression in the next day. This is the forum page for the 2020-21 South Pacific cyclone season. [14] Prema brought strong to gale-force winds and high seas to the Northern Cook Islands of Penrhyn, Manihiki, Rakahanga and Pukapula. The BoM also predicted that the Eastern Region between 165°E and 120°W, had a 45% chance of seeing activity above its average of 6 tropical cyclones. [2][4] The BoM issued two seasonal forecasts for the Southern Pacific Ocean, for their self-defined eastern and western regions of the South Pacific Ocean. 3). NIWA and MetService analyses indicate 9 to 12 named tropical cyclones (TC) could occur in the Southwest Pacific basin between November 2019 and April 2020. Parts of Northeast socked by waist-deep snow. The service noted that these figures were revised in August with the expectation of 19 to 25 named storms, seven to eleven hurricanes and three to six major hurricanes. Plus, big heat for the East and winter weather out West. But let's not forget there were other significant storms that season, too. [26] Zazu continued to strengthen even as it began an extratropical transition, reaching Category 2 status on the Australian scale on December 15, despite struggling with the effects of westerly wind shear. During February 25, a depression developed within a trough of low pressure, to the south-west of Manihiki in the Northern Cook Islands. Yasa formed on December 11 and became a Category 5 cyclone, impacting Fiji. [13][14] The remnants of Prema were subsequently monitored over the next few days, as they moved towards and through French Polynesia, before they were last noted during March 6. [19] During April 2, the system started to rapidly weaken, with its high clouds being sheared away, before it degenerated into a mid latitude depression. [13] Gale-force winds caused some serious damage to a wharf, on the atoll of Penhryn. [8], During December 10, a shallow tropical depression formed to the west of the Northern Cook Island: Penrhyn and started to move south-eastwards towards French Polynesia. [5] At this stage, the system had a broad low level circulation and was located within a marginal environment for further development, with warm sea surface temperatures as well as moderate levels of vertical wind shear. The most active time of year is ahead. [8] The depression continued to consolidate, with deep convection wrapping into the centre of the system from the northern semicircle, and by 12:00 UTC, one-minute sustained winds had increased to 75 km/h (45 mph). [5][6] Within northern Vanautu, Joti damaged houses, gardens and fruit trees. [11][12] Due to the deteriorating structure of the system, the FMS ceased advisories on Tropical Depression 01F at this time. Yasa caused catastrophic damge and four deaths in Fiji. Please sign your comments using four tildes (~~~~). 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. After making landfall, Yasa moved into an area of unfavourable conditions, causing the storm to rapidly weaken, with Yasa weakening into a Category 3 severe tropical cyclone later that day. This hurricane season has rewritten the record books. Nano existed from January 21 to January 29. The South Pacific tropical cyclone season is typically from 1 November to 30 April. [6] During that day the system started to move towards the west-south-west and made landfall on the northern Espiritu Santo. This table lists all the storms that developed in the South Pacific to the east of 160th meridian during the 2020–21 season. During March 27, the FMS started to monitor a depression that had developed, within a trough of low pressure about 235 km (145 mi) to the northeast of Penrhyn in the Northern Cook Islands. Another disturbance formed near the existing 01F and rapidly intensified into a depression. [7] At 00:00 UTC on December 11, the JTWC upgraded the system to a tropical storm on the Saffir–Simpson hurricane wind scale. [20] Soon afterwards, the JTWC upgraded Yasa to a Category 1-equivalent cyclone on the Saffir–Simpson scale.[21]. The peak months for hurricanes in the Atlantic, Caribbean, and Pacific are August through early October. [12] The storm then weakened and degenerated into a low pressure system later on December 12. [3] At least four of the tropical cyclones were expected to intensify further and become severe tropical cyclones, while it was noted that a Category 5 severe tropical cyclone could occur during the season. [13] Heavy rain and gale-force winds off 100 km/h (60 mph), caused minor damage to French Polynesia's Leeward and Society Islands.[15][16]. [14], Tropical Disturbance 02F was first noted by the FMS during December 11, while it was located about 800 km (495 mi) to the northeast of Port Villa in Vanuatu. [27] During December 16, the system moved into MetService's area of responsibility, before they reclassified it as an extratropical low later that day. [3], In addition to contributing towards the Island Climate Update outlook, the FMS and the BoM issued their own seasonal forecasts for the South Pacific region. [13] On the atoll of Manihiki, the high seas reached the settlement, with minor damage to coconut trees reported as a result. William was one of the most northeasterly forming cyclones in the basin's history. (A tutorial on El Niño and La Niña can be found at the NOAA Climate Prediction Center website.) *Spanish translations, when available, are courtesy of the NWS San Juan Weather Forecast Office. During the season tropical cyclones were monitored by the meteorological services of Australia, Fiji, French Polynesia and New Zealand. Eight products are displayed, most notably an inner core scale surface wind analysis. Oscar existed from February 23 to March 6. On December 13, 15:00 UTC, 02F intensified into a Category 1 tropical cyclone Yasa according to Australian scale. The season officially started on November 1, 2020 and will end on April 30, 2021, however a tropical cyclone could form at any time between July 1, 2020 and June 30, 2021 and would count towards the season total. This expectation for tropical cyclone activity is close to normal for the region, but with elevated activity east of the International Date Line especially during the late season between February and April. 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. There is relatively low disagreement between the analogues for the total number of cyclones for this season, with the one exception being the 2007/08 season. [15] At 00:00 UTC on December 12, the Fiji Meteorological Service (FMS) upgraded the system to Tropical Depression 02F, and began issuing forecast track maps. [8] The degenerating system subsequently passed to the west of Fiji during November 13, before it was last noted during November 16, as it passed over the island of Efate in Vanuatu but no damage was reported. [12] The system subsequently moved in a counter clockwise loop, which allowed it to develop further and it was declared to be a tropical cyclone and named Nisha by the FMS during February 22. At the same time, the equatorial Walker circulation is weaker than average. 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. It hampered the system intensification due to a brief interaction with Tropical Depression 01F. This Travel Alert expires on April 30, 2012. The latest typhoon watches and warnings for the South Pacific Basin. [13], 01F caused heavy rain in American Samoa, with a peak rainfall total of 62 mm (2.44 in) recorded at the Pago Pago International Airport. During the season tropical cyclones were monitored by the meteorological services of Australia, Fiji, French Polynesia and New Zealand. These conditions produce an anomalous upper-level, ridge-trough pattern in the subtropics, with an amplified ridge over the subtropical Pacific in the ar… Late on December 19, Yasa transitioned into an extratropical storm, issuing their final advisory. RSMC Nadi, TCWC Wellington and TCWC Brisbane all use the Australian Tropical Cyclone Intensity Scale and estimate windspeeds 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). [6] Over the next couple of days, the system gradually moved westwards before the FMS classified it as a tropical depression during December 11, while it was located about 280 km (175 mi) to the west of the Fijian Dependency of Rotuma. [15] The JTWC also noted a Fujiwhara interaction with 01F, which briefly hampered the development of the system. [18] Tomasi remnants moved towards the south-southeast, before it was last noted during April 5. [8] Tourists on the Blue Lagoon Cruise in the Yasawas were forced to take shelter from Kina, while 18 people on another boat were temporarily listed as missing as they took shelter. [3] The outlook called for a near-average number of tropical cyclones for the 2020–21 season, with nine to twelve named tropical cyclones, predicted to occur between 135°E and 120°W, compared to an average of just over 10. The 1982–83 season was one of the most active and longest South Pacific tropical cyclone seasons on record, with 14 tropical cyclones occurring within the South Pacific basin between 160°E and 120°W. The full hurricane season is June 1st to November 30th for the Atlantic and the Caribbean each year, and the Eastern Pacific hurricane season starts in mid-May. The Atlantic Hurricane Basin. [19] Tomasi subsequently turned and started to move southwards, as it passed about 165 km/h (105 mph) to the east of Niue. FP normally only experiences cyclones during El Nino years when sea temperatures farther east are warmer than the average. The first tropical cyclone of the season is brewing across the South Pacific and it can bring impacts to Fiji and Vanuatu. Because of the Fujiwhara effect, the remnant was absorbed by Tropical Depression 02F shortly afterward, which would later become Severe Tropical Cyclone Yasa. [9] By 00:00 UTC on December 12, both the JTWC and the FMS reported that the shear had displaced the system's deep convection to the northeast, leaving the centre of circulation fully exposed. There are no tropical cyclones in the Atlantic at this time. Five of these tropical cyclones went on to affect the island nation of French Polynesia, which it was thought had not been affected by a tropical cyclone since another very strong El Nino episode in 1905-06. Rewa exacerbated the destruction caused by Severe Tropical Cyclone Nisha/Orama earlier in the season and destroyed more than 200 houses. The 2020–21 South Pacific cyclone season is a currently ongoing period of the year when most tropical cyclones form within the South Pacific Ocean to the east of 160°E. [11] The 2018–19 season was one of the most active and longest South Pacific tropical cyclone seasons on record, with 14 tropical cyclones occurring within the South Pacific basin between 160°E and 120°W. [22] The storm continued rapidly intensifying and strengthened to a Category 5 tropical cyclone on the Australian scale, the highest rating possible, whilst completing its loop, with a central pressure of 929 mbar and wind speeds of 110 knots (125 mph). Featuring Winston! The Eastern Pacific basin extends to 140°W. The 2051-52 South Pacific cyclone season was a slightly active season. The National Oceanic and Atmospheric Administration (NOAA) predicted a more active Atlantic hurricane season than normal for 2020, and A potential combination of 3-4 cyclones may reach severe category 3 or higher status. Most of the activity during the season occurred within the central and eastern parts of the basin with French Polynesia affected by several systems. [11] Over the next couple of days, the system gradually developed further before the FMS reported that the system had developed into a tropical cyclone and named it Lisa during December 12. [8][9] The FMS subsequently estimated during the next day that the system had reached its peak intensity, with 10-minute sustained winds of 75 km/h (45 mph) during November 11. The Western Pacific Basin has been eerily quiet so far in 2019, with roughly half the tropical cyclone activity of an average year through July. [19] Later that day, the FMS reported that Tomasi had peaked as a Category 4 severe tropical cyclone, with 10-minute sustained winds of 185 km/h (115 mph). The United States Armed Forces through the Joint Typhoon Warning Center (JTWC) will also monitor the basin and issue 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. [13][14] The system was named Prema by the FMS during the next day, after it had developed into a category 1 tropical cyclone and peaked, with 10-minute sustained winds of 85 km/h (50 mph). The incidence of cyclones farther west, where sea temperatures are warmer, is higher. During December 11, the FMS reported that Tropical Disturbance 03F had developed about 480 km (300 mi) to the northeast of the island nation of Niue. The historic long-term seasonal average is just over 10 named cyclones for the SW Pacific basin. [12] Over the next four days the system maintained its intensity, before it made a sharp eastwards turn and started to develop further.
