The JTWC considered the disheveled cyclone as subtropical in nature, remaining in an environment hostile to increased organisation. Nutfield001 (talk) 15:58, December 13, 2020 (UTC), C3 on the AUS scale, high-end C1 (SSHWS) per JTWC.  Imagery from microwave satellite data showed emergent rainbands wrapping towards an organising center of low pressure.  However, it failed to develop any further and was last noted by the FMS during December 23, after it had lost its tropical characteristics and became extratropical. Nutfield001 (talk) 22:54, December 8, 2020 (UTC), Upgraded to a tropical depression per FMS whilst the JTWC now has this as a TC with 35 kt winds. The season runs throughout the year, though most tropical cyclones typically develop between May and October.  Over the next few days, the system moved south-westwards within an area that was marginally favourable for further development, with good poleward outflow and warm sea surface temperatures offset by low to moderate vertical wind shear. Seasonal boundaries; First system formed: November 3, 2020: Last system dissipated: May 10, 2021: Strongest storm; Name: Fili • Maximum winds : 205 km/h (125 mph) (10-minute sustained) • Lowest pressure: 934 hPa : Seasonal …  The JTWC assessed Harold three hours later as having one-minute sustained winds of 215 km/h (130 mph), equivalent to a Category 4 hurricane on the Saffir–Simpson scale. Nutfield001 (talk) 02:05, 18 December 2020 (UTC), Now C2 on Australian scale, C1 on SSHWS.  The extratropical remnants of Uesi reentered the South Pacific basin on a southeasterly heading towards South Island on February 15. The 2020-21 Southern Hemisphere Cyclone season is an upcoming event in meteorology that will encompass the regions of the Australian region, the Southwest Indian Ocean, the South Pacific Ocean, and the South Atlantic.  Power outages afflicted at least 3,900 households serviced by EEC and Enercal and over 5,000 overall.  Sarai's center of circulation became displaced from the storm's convection on December 30, and the storm weakened to Category 1 strength. In contrast, the FMS expects C1 (AUS scale) strength at the end of their forecast period.  Routine advisories were initiated by the FMS the same day while 06F drifted towards the south-southwest. The FMS is expecting C5 intensity (AUS scale again) by the time it races southeastwards towards Fiji. Loading... Unsubscribe from Weather Follower? Tropical depressions that intensify into a tropical cyclone between the Equator and 25°S and between 160°E and 120°W are named by the FMS.  The FMS upgraded Gretel to a Category 2 cyclone at 12:00 UTC that day. , Both the Island Climate Update and the FMS tropical cyclone outlooks assessed the risk of a tropical cyclone affecting a certain island or territory. This originally was going to receive the name Yolanda but that was removed without being used, presumably because of Haiyan.  Despite lacking a clear wind circulation within a chaotic environment—the JTWC initially considered the disturbance to be a hybrid tropical system rather than a tropical cyclone—the region's warm sea surface temperatures and low wind shear were supportive of further organisation. The VMGD said that as compared to others, the cyclone risk level for this cyclone season is "normal to normal-elevated risk".  The disturbance was also located to the north of a subtropical ridge of high pressure, within a favourable environment for further development, with a low to moderate amount of vertical wind shear and warm sea surface temperatures of 29–30 °C (84–86 °F). , During March 15, Tropical Cyclone Gretel moved into the basin from the Australian region, about 620 km (385 mi) to the northwest of Nouméa in New Caledonia.

Continuing to intensify in favorable atmospheric conditions, Rita reached Category 2 cyclone strength by November 25 and Category 3 intensity six hours later. , 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. The average numbers of tropical cyclones during the season in the western and eastern regions are six and four, respectively. It strengthened into severe tropical cyclone Uesi and affected New Caledonia and New Zealand. The Vanuatu Meteorology and Geo-Hazards Department also issued a tropical cyclone warning for these areas.  At least two of the tropical cyclones were expected to intensify further and become Category 3 or higher severe tropical cyclones. Cancel Unsubscribe. Nutfield001 (talk) 03:29, December 11, 2020 (UTC), Now a tropical depression per FMS as JTWC issues a TCFA on this system.  Two homes were destroyed and six sustained major damage from the combined effects of Cyclones Wasi and Cyclone Vicky in American Samoa, which had struck the territory in the same week. Code yellow on JTWC. The latest typhoon watches and warnings for the South Pacific Basin. The next 10 names on the naming list are listed here below.. ; Please keep off-topic and political discussion to a minimum, and respect the guidelines listed to the right. Large waves along the island's coast forced the closure of the seawall road.  The next day, the storm passed near Vanua Levu and strengthened further into a Category 2 cyclone as an emerged; Category 3 intensity was reached later that day with 10-minute sustained winds estimated at 120 km/h (75 mph).  Atmospheric conditions were supportive of further intensification within the South Pacific as the storm tracked towards the southeast.  The developing eye briefly emerged on infrared and visible satellite imagery as a ragged feature at the cyclone's center, surrounded by well-defined rainbands. 07F turned towards the southwest by February 20, where strong wind shear began to degrade the convective structure of the system.  The large extratropical stage of Uesi produced 6–8 m (20–26 ft) waves off the northwestern shores of South Island. Northwest Pacific Storms.  Additionally, a father and daughter were left missing after being swept away from floodwaters due to heavy rainfall generated by the system in Eastern Fiji.  Their outlook also predicted that Vanuatu, the Northern Cook Islands, French Polynesia's Society Islands had a reduced chance of being affected by a tropical cyclone, while tropical cyclone activity near Kiribati and the Marquesas Islands was considered unlikely. It also has a very large and well-defined eye with seemingly annular traits, so Yasa could maintain its intensity before striking Fiji. Warnings were issued by the Vanuatu Meteorology and Geohazards Department for Uesi, noting the possibility of stream and coastal flooding.  The system finally began to weaken as it accelerated towards Tonga. Rita would then peak as a Category 3 on the Australian scale.  Wasi was the second tropical cyclone to affect the Samoan islands in two days.  After an extended period of slow movement, 07F accelerated south of Samoa on February 19.  On the next day, the storm began an extratropical transition while it moved into MetService's area of responsibility.  The east-southeastward-moving storm was upgraded to a tropical depression the next day, prompting routine advisories from the FMS. Personally, due to the possibility of La Niña conditions, I will not be surprised if this season's overall activity is below average.  By February 18, the JTWC declared the disturbance to have dissipated. In Fiji, heavy rain alerts were issued for the western half of Viti Levu, Kadavu, and the Mamanuca and Yasawa islands on April 6.  The outlook called for a near-average number of tropical cyclones for the 2019–20 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. Nutfield001 (talk) 07:33, December 14, 2020 (UTC), Still alive, although in extratropical form. Absorption of this system by 01F seems to be the most probable scenario. Period of tropical cyclone activity in the South Pacific Ocean.  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. , As Tino passed close to Vanua Levu, the second cyclone to pass near the nation within three weeks following Sarai, Fijian government officials called for urgent action on the 'climate crisis' in the South Pacific region. activates Emergency response as Samoa braces for cyclone Wasi", "Samoa govt activates Emergency Ops Center, monitors likely track of Wasi", "Samoa prepares for Wasi, activates Emergency Operations Centre", "Samoa drenched by rain as TC Wasi warning remains", "Residents stranded after Cyclone Wasi floods rivers in Samoa", "Samoa Airways Service to Pago Pago Resumes Today", "Cyclones leave homes in American Samoa damaged", "Warning for Niue cancelled as Cyclone Wasi dissipates", "Tropical Cyclone Gretel Forecast Track Map #17 (00Z)", Tropical Cyclone 23P (Gretel) Warning NR 002, "[MàJ] Gretel s'éloigne par le Sud-Ouest mais la Calédonie subit encore son influence", Tropical Cyclone 23P (Gretel) Warning NR 003, Tropical Cyclone 23P (Gretel) Warning NR 004, Tropical Cyclone 23P (Gretel) Warning NR 005, Tropical Cyclone 23P (Gretel) Warning NR 006, "Dépression tropicale Gretel : la province Sud en alerte cyclonique de niveau 1 à 15h [MÀJ]", "Dépression Gretel : la préalerte cyclonique levée sur la province des Iles, levée de l'alerte 1 pour le Nord à 8h et le Sud à 11h", "Gretel : les centres d'accueil opérationnels dans le Grand Nouméa", "Dépression Gretel : les vols Aircalin chamboulés", "Gretel : annulation de tous les bus Raï ce dimanche", "Mesures de prévention liées au phénomène climatique GRETEL", "A Pouembout, le collège de Païamboué est fermé jusqu'à mercredi", "Gretel au plus près du Caillou cette nuit", "Dépression Gretel : près de 800 foyers sans électricité [MàJ]", "Municipales : un scrutin perturbé par les intempéries dans l'extrême Nord", "Le Sud bascule à son tour en alerte 1, comme le Nord", "[MàJ 11h40] La province Sud passe à son tour en alerte 1 à 15 heures", "Dépression Gretel : une barge sous le pont de Nouville", Tropical Cyclone Harold Technical Bulletin April 3, 2020 00z, Tropical Disturbance Advisory A1 for Tropical Cyclone Harold April 3, 2020 06z, Tropical Cyclone 25P (Harold) Warning NR 002, Tropical Cyclone 25P (Harold) Warning NR 003, Tropical Cyclone 25P (Harold) Warning 4 April 3, 2020 15z, Tropical Cyclone 25P (Harold) Warning NR 006, Tropical Cyclone 25P (Harold) Warning NR 008, "Cyclone Harold updates: Storm makes landfall on Vanuatu's Santo", "Hurricane Warning 026 for Severe Tropical Cyclone Harold", "Cyclone Harold Slams Into Fiji As Category 5 Storm", "Cyclone Harold slams Tonga, third island nation hit in 3 days", Tropical Cyclone 25P (Harold) Warning 28 April 9, 2020 15z, Tropical Cyclone 25P (Harold) Running Best Track Analysis, "TC Harold batters Solomon Islands as it heads to Vanuatu", "Solomon Islands is Bracing Itself for Tropical Cyclone Harold", "Australia donates emergency funds to Solomons amid cyclone", "Ferry accident during Solomon Islands cyclone leaves 28 missing", Tropical Cyclone Operational Plan for the South-East Indian Ocean and the Southern Pacific Ocean 2020, https://en.wikipedia.org/w/index.php?title=2019–20_South_Pacific_cyclone_season&oldid=995508387, Pages containing links to subscription-only content, Articles with unsourced statements from March 2020, Articles with unsourced statements from April 2020, Creative Commons Attribution-ShareAlike License, Category 2 tropical cyclone (Australian scale), Category 3 severe tropical cyclone (Australian scale), Category 1 tropical cyclone (Australian scale), Category 5 severe tropical cyclone (Australian scale), New Caledonia, Norfolk Island, New Zealand, This page was last edited on 21 December 2020, at 12:24.

The addition of strong vertical wind shear caused Gretel's remaining showers and thunderstorms to dislocate from the central vortex.  Its center tracked near Nukuʻalofa on December 31 while the storm's structure rapidly deteriorated, with the JTWC issuing their final advisory that day.  The FMS issued their last advisory on Rita on November 26 after the storm was downgraded to a remnant area of low pressure; at the time these remnants were slowly moving west-southwest towards northern Vanuatu. Keep betting pools off this page - there are separate forum pages for those. The system was poorly organised, with a high wind shear environment displacing convection to the northeast of the low-level center of circulation as the disturbance moved southeast to east-southeast.  Rainfall associated with the passing storm also caused flooding, forcing dozens of families out of their homes. During April 3, Tropical Cyclone Harold moved into the basin from the Australian region, as a Category 1 tropical cyclone on the Australian scale. , Vanuatu and the French territory of New Caledonia were threatened by Uesi along its southward trek through the South Pacific basin.  This circulation quickly slackened during the day. Yasa might actually have its circulation pass just between Viti Levu and Vanua Levu if it follows the center of the current JTWC track, but a slight deviation to the right or left would lead to a landfall, and the large size of Yasa means impacts will be significant even if it doesn't directly make landfall on either of the two main islands.  Within their outlook the FMS predicted that between five and eight tropical cyclones, would occur within the basin compared to an average of around 7.1 cyclones. Additionally, as of December 29, 2019, 2 deaths have been confirmed related to the cyclone due to drowning in floodwaters. Not too long after that, Tino formed and affected eastern Fiji and the surrounding area before dissipating. Nutfield001 (talk) 17:32, December 12, 2020 (UTC), Alongside 01F, RSMC Nadi are also hinting at another system near Rotuma, and is expected to form into 02F by tomorrow. Nutfield001 (talk) 05:59, December 12, 2020 (UTC), Intensified to a C1 TC per FMS and assigned the name Yasa. History Talk (0) Comments Share.
