It have become extratropical on November 20. 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. [18] It was also classified as a Category 3 severe tropical cyclone, before a tropical cyclone alert was issued by the FMS for Niue at around 23:08 UTC (11:08 FST, March 30). 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. These conditions produce an anomalous upper-level, ridge-trough pattern in the subtropics, with an amplified ridge over the subtropical Pacific in the ar… 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 Australian tropical cyclone region extends from 90°E to 160°E, south of the equator, and is part of a continuum of tropical cyclone activity that extends from the coast of Africa to French Polynesia in the South Pacific (Fig. 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. [7] At 00:00 UTC on December 11, the JTWC upgraded the system to a tropical storm on the Saffir–Simpson hurricane wind scale. [2], After the season had officially ended during April 30, meteorologists at the University of Hawaii identified that two tropical depressions developed on May 11 and May 16. 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. All meteorological data is taken from the warning centers while damage estimates are in 2021 USD. [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. [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. [5] The disturbance was subsequently named Joti at 00:00 UTC on November 1, by the FMS as it had developed into a tropical cyclone. [13] Gale-force winds caused some serious damage to a wharf, on the atoll of Penhryn. The peak months for hurricanes in the Atlantic, Caribbean, and Pacific are August through early October. The Atlantic hurricane season runs from June 1st through November 30th. [12] The Tuamotu Archipelago was the worst hit area with around 30 of its Atolls, either seriously damaged or destroyed with a damage total of around US$1.7 million reported in two villages on Rangiroa.[12]. [7] Environmental conditions were very favourable for tropical cyclogenesis, with radial outflow in the upper troposphere, low vertical wind shear, and sea surface temperatures near 30 °C (86 °F). [27] During December 16, the system moved into MetService's area of responsibility, before they reclassified it as an extratropical low later that day. [11] [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. [17] The system subsequently gradually deepened as it moved south-eastwards and passed to the west of the island, before it was named Sarah by the FMS during March 24, after it had developed into a tropical cyclone. While cyclones in this area of the Pacific Ocean may occur year-round, December through April are usually the most active months. During the season, tropical cyclones will be officially monitored by the Fiji Meteorological Service (FMS), Australian Bureau o… 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. Only seven hurricanes formed, the fewest since 2010. Convective rainbands began to develop around the system as it tracked slowly eastwards, wrapping into the low-level circulation centre. It hampered the system intensification due to a brief interaction with Tropical Depression 01F. [28], Yellow cyclone alerts (the third highest level) were issued for the island of Niue on December 15, while residents were taken to higher grounds by officials. 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. Yasa became the most intense tropical cyclone of 2020, surpassing Goni with a minimum barometric pressure of 899 mb (26.55 inHg) and a maximum wind speed of 250 km/h (155 mph). *Spanish translations, when available, are courtesy of the NWS San Juan Weather Forecast Office. This hurricane season has rewritten the record books. At the same time, the equatorial Walker circulation is weaker than average. The season was characterised by a very strong El Niño event, which resulted in eleven tropical cyclones occurring to the east of the International Dateline. 3). [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. [7], The system that was to become Tropical Cyclone Kina was first noted on November 6, while it was located just to the east of Tuvalu. Yasa formed on December 11 and became a Category 5 cyclone, impacting Fiji. [18][19] Over the next couple of days, the system moved south-westwards and passed about 140 km (85 mi) to the southeast of Penhryn, as it gradually developed into a tropical cyclone. [15] The JTWC also noted a Fujiwhara interaction with 01F, which briefly hampered the development of the system. The next 10 names on the naming list are listed here below.[32]. [20] Soon afterwards, the JTWC upgraded Yasa to a Category 1-equivalent cyclone on the Saffir–Simpson scale.[21]. [13][14] After it had been named: Prema moved south-eastwards and started to gradually weaken, before it degenerated into a depression during February 27. Includes the waters of: the North Atlantic Ocean, the Gulf of Mexico, … Tropical cyclones affect Pacific island countries in most years and can impact coastal regions even when they remain well offshore. 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. The National Oceanic and Atmospheric Administration (NOAA) predicted a more active Atlantic hurricane season than normal for 2020, and During March 7, a tropical depression developed about 650 km (405 mi) to the northeast of the Society Islands. This is the forum page for the 2020-21 South Pacific cyclone 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. During December 8, the FMS reported that Tropical Disturbance 01F had developed about 145 km (90 mi) to the northeast of Apia in Samoa. [9] During that day the FMS also reported that the system had developed into a Category 1 tropical cyclone on the Australian Scale and named it Kina. Yasa continued its rapid intensification trend and further intensified to the equivalent of a high-end Category 4 tropical cyclone on the Saffir–Simpson scale (SSHWS), developing a well-defined and very clear eye, while continuing to become more symmetrical. [18] Early on March 31, the NPMOC reported that the cyclone had peaked with 1-minute sustained winds of 189 km/h (117 mph), which made it equivalent to a Category 3 hurricane on the SSHWS. The storm continued to intensify and soon became a Category 3 on the Australian scale. [12] The storm then weakened and degenerated into a low pressure system later on December 12. [1], During the season, ten of the fourteen tropical cyclones observed to the east of 160 E were severe tropical cyclones, with 5 of them occurring in the French Polynesia region which represented one more than was experienced in the same area over the previous 13 seasons. 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. [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). Eight products are displayed, most notably an inner core scale surface wind analysis. Most of the activity during the season occurred within the central and eastern parts of the basin with French Polynesia affected by several systems. Should a tropical cyclone move out of the basin and into the Australian region it will retain its original name. [5] As a result, this made Joti one of the earliest tropical cyclones ever recorded within the basin. However, if a tropical depression intensify to the south of 25°S between 160°E and 120°W it will be named by MetService in conjunction with the FMS. But let's not forget there were other significant storms that season, too. During the season, tropical cyclones will be officially monitored by the Fiji Meteorological Service (FMS), Australian Bureau of Meteorology (BoM), New Zealand's MetService. [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. [9][10] The system caused strong winds and rough seas on Viti Levu and in the Yasawas and Mamanutha group of islands. [4], The system that was to become Tropical Cyclone Joti was first noted by the Central Pacific Hurricane Center (CPHC) during October 30, while it was located about 1,000 km (620 mi) to the north-east of Port Villa in Vanuatu. The most intense tropical cyclone in the south Pacific, Cyclone Winston of 2016, is also the most … Please keep off-topic and political discussion to a minimum, and respect the guidelines listed to the right. The 2006–07 South Pacific cyclone season was an event in the annual cycle of tropical cyclone formation. [17][18] At 15:00 UTC December 12, the JTWC determined the system had strengthened into Tropical Cyclone 05P and was now producing winds up to gale force, while it absorbed the remnant of Tropical Depression 01F. [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. With tropical depressions intensifying into a tropical cyclone between the Equator and 25°S and between 160°E - 120°W named by the FMS. [10] However, environmental conditions were only marginally conducive for intensification, with strong vertical wind shear inhibiting further development. [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. Because of the Fujiwhara effect, the remnant was absorbed by Tropical Depression 02F shortly afterward, which would later become Severe Tropical Cyclone Yasa. 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. [10] The system's organisation improved steadily over the next few days, and at 12:00 UTC on December 13, the Joint Typhoon Warning Center (JTWC) upgraded the depression to a tropical storm on the Saffir-Simpson hurricane wind scale. The Atlantic hurricane season runs from June 1st through November 30th. 01F became a remnant low and got absorbed by Tropical Depression 02F. This Travel Alert expires on April 30, 2012. [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. 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. Featuring Winston! 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. The Eastern Pacific basin extends to 140°W. The most active basin in the year was the North Atlantic, which documented 28 named systems.The Western Pacific had an near-average season with 23 named storms. The latest typhoon watches and warnings for the South Pacific Basin. [19] Tomasi subsequently turned and started to move southwards, as it passed about 165 km/h (105 mph) to the east of Niue. [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. 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. The 2005 was above-average in terms of the number of storms. [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. During the season tropical cyclones were monitored by the meteorological services of Australia, Fiji, French Polynesia and New Zealand. A potential combination of 3-4 cyclones may reach severe category 3 or higher status. The United States Armed Forces through the Joint Typhoon Warning Center (JTWC) and Naval Pacific Meteorology and Oceanography Center (NPMOC), al… [23] This was the earliest date a Category 5 South Pacific tropical cyclone formed on record and only the second Category 5 South Pacific tropical cyclone recorded in the month of December. [9] A few hours later, the FMS estimated maximum 10-minute sustained winds to be at 55 km/h (34 mph), with a minimum central atmospheric pressure of 998 hPa (29.47 inHg). 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. Rewa exacerbated the destruction caused by Severe Tropical Cyclone Nisha/Orama earlier in the season and destroyed more than 200 houses.
