[181] Two rivers in Savai'i flooded their banks and inundated adjacent roads. [3] The outlook took into account the ENSO neutral conditions that had been observed across the Pacific and analog seasons, that had ENSO neutral and El Nino conditions occurring during the season. [236][237] 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. All COVID-19-related activities were also cancelled in order to prepare for the impact of Harold. During the season, tropical cyclones are officially monitored by the Fiji Meteorological Service (FMS), Australian Bureau of Meteorology (BOM) and New Zealand's MetService. [69] However, Tino soon began to entrain dry air, resulting in a gradual decay of its convection and subsequent weakening on January 18 as the center tracked across Ha'apai. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA): A. [114][115] Flights serviced by Air Calédonie were also delayed. [111] Météo France (MFR) issued thunderstorm and rain warnings for four municipalities in New Caledonia on February 9,[112] and later raised warnings to an orange alert for six the following day.

[109] The extratropical remnants of Uesi reentered the South Pacific basin on a southeasterly heading towards South Island on February 15. Cyclones can affect Queensland, the Northern Territory and the South Pacific between November and April according to Australia's Bureau of Meteorology. [88][89] The system subsequently moved south-eastwards into an area of moderate vertical wind shear, while atmospheric convection became sheared and located to the northeast of the disturbance's exposed low-level circulation centre. In early February, another low originally in the Australian region crossed the 160th meridian east and emerged in the South Pacific. The FMS issued the final advisory on the system on February 21 while it was passing to the south of Niue. Tropical Cyclone Floaters | Pacific Imagery: Bulletins: Microwave Positions: Text bulletins disseminated by 0400Z, 1000Z, 1600Z, and 2200Z describing the position and intensity estimates for tropical disturbances and tropical cyclones in the Eastern and Southern Hemispheres. [125] The large extratropical stage of Uesi produced 6–8 m (20–26 ft) waves off the northwestern shores of South Island. [213][214] Atmospheric conditions were supportive of further intensification within the South Pacific as the storm tracked towards the southeast. [153], During February 21, the FMS reported that Tropical Disturbance 10F had developed, about 145 km (90 mi) to the north of Mata Utu on the island of Wallis.

The VNDMO advised for all residents under the red alert to remain indoors. [231][232][233] Rainfall associated with the passing storm also caused flooding, forcing dozens of families out of their homes. While a little less frequent are cyclones in the area that goes from the Solomon Islands, the Samoa islands, the southern Cook Islands, to the Tuvalu. In early April, Harold also entered the basin from the Australian region. [85][86] At this time, the disturbance was poorly organised with atmospheric convection located to the north of its low-level circulation center. The season officially ran from November 1, 2019 to April 30, 2020, however a tropical cyclone could form at any time between July 1, 2019 and June 30, 2020 and would count towards the season total. [2] At least two of the tropical cyclones were expected to intensify further and become Category 3 or higher severe tropical cyclones. [146] Later that day, the center of 08F continued past the 25th parallel south, leading the FMS to issue their final tropical disturbance summary on the highly sheared system. ABPW10 (Western/South Pacific Ocean) Issued at 23/0600Z; ABIO10 (Indian Ocean) Issued at 22/1800Z; Satellite Image; Products on this website are intended for use by U.S. government agencies. It includes their intensity on the Australian tropical cyclone intensity scale, duration, name, landfalls, deaths, and damages. [225] The system finally began to weaken as it accelerated towards Tonga. Tropical cyclone - Tropical cyclone - Location and patterns of tropical cyclones: Tropical oceans spawn approximately 80 tropical storms annually, and about two-thirds are severe (category 1 or higher on the Saffir-Simpson scale of intensity). [126], During February 14, the FMS reported that Tropical Disturbance 07F had developed, about 490 km (305 mi) to the northeast of Funafuti in Tuvalu. [134] Before 07F's arrival, a moisture-laden convergence zone had already been affecting Samoa with heavy rainfall and high winds. Cyclone warnings were issued for the entirety of the Solomon Islands as Harold approached on April 3. Current Conditions Satellite Hydrology Analyses/Forecast Charts Observations. West and South Pacific Cyclones. [85][87] As a result, atmospheric convection started to wrap into the system's consolidating low-level circulation center, which prompted the JTWC to issue a tropical cyclone formation alert on the disturbance. [122] Gusts of up to 120 km/h (75 mph) impacted New Caledonia's central mountain range.

[2][3] The Island Climate Update Outlook predicted that American Samoa, French Polynesia's Austral Islands, Niue, Samoa, Tonga, Tuvalu as well as the Solomon Islands and Southern Cook Islands had an elevated chance, while the Wallis and Futuna had a normal to elevated chance of being impacted by a tropical cyclone. Three tropical cyclones are tied for being the most powerful storms on record in the South Pacific (all with 180 mph winds): Tropical Cyclone Winston (2016), Tropical Cyclone Zoe (2002), and Tropical Cyclone Monica (2006). [193] Some roads were blocked by downed trees. The following table is a list of the … FORECAST TO 1200 UTC SAT 24-APR-2021 No tropical cyclones are expected. [23][24] 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. The World Meteorological Organization Tropical Cyclone Programme is tasked to establish national and regionally coordinated systems to ensure that the loss of life and damage caused by tropical cyclones are reduced to a minimum. The South Pacific tropical cyclone season is typically from 1 November to 30 April. [162] Brief power outages affected parts of Samoa early on February 21. It dissipated shortly afterwards.

[145] By February 18, the JTWC declared the disturbance to have dissipated. The season officially ran from November 1, 2004 to April 30, 2005, however a tropical cyclone could form at any time between July 1, 2004 and June 30, 2005 and would count towards the season total. Following a decrease in wind shear, the FMS upgraded 04F to a tropical depression on January 15 as it began to organize. The BoM also predicted that the Eastern Region between 165°E and 120°W, had a 41% chance of seeing activity above its average of 7 tropical cyclones. [75] A Tropical Cyclone Warning was subsequently issued for Rotuma on January 15, and a Tropical Cyclone Alert for the rest of the Fijian islands. [95] Routine advisories were initiated by the FMS the same day while 06F drifted towards the south-southwest. However, the riskiest months are January to March with significantly lower probabilities of a major event at the start and end of the season. South-West Pacific Ocean Global View . [87] During the next day, the JTWC intiated advisories on the disturbance and designated it as Tropical Cyclone 12P, as the system peaked with 1-minute sustained windspeeds of 65 km/h (40 mph).

[224] Later that day, it reached Category 4 status on the SSHWS yet again. [230] Strong winds blew down trees in Honiara, causing power outages and blocking roads. [citation needed]. [101] Uesi strengthened further into a Category 3 tropical cyclone at 18:00 UTC that day but continued to be affected by the entrainment of dry air. [123] Power outages afflicted at least 3,900 households serviced by EEC and Enercal and over 5,000 overall. [153][154] Continuing to track towards the east-southeast, the depression strengthened into a Category 1 tropical cyclone later that day, receiving the name Vicky. [142][143] The JTWC considered the disheveled cyclone as subtropical in nature,[144] remaining in an environment hostile to increased organisation. The cyclone was one of few cyclones recorded in the far Southeastern Pacific, and was therefore not tracked by RSMC Fiji or RSMC Wellington. : click on the Australian scale to remain indoors, Queensland beginning that day, the FMS issued final!
