[86] After reaching the Dampier Peninsula on 20 December, the system turned sharply to the east and began tracking further inland. [47][48] Initially lacking organised deep convection, the system proceeded to track in a generally southwards direction towards the Kimberley region of Western Australia. Cyclones, dangerous rain feared as La Niña forms Australia's eastern states are likely to experience dangerous weather events, with the Bureau of Meteorology declaring La Niña has developed in the Pacific Ocean. By late on 7 December, infrared satellite imagery indicated an improvement in the structure of the low, with the system displaying an increase in flaring deep convection, accompanied by rotation evident in the lower troposphere. [6][7] On 24 November, the Bureau of Meteorology (BOM) reported that a tropical low had developed within a trough in the far northwestern corner of the Australian region, located approximately 860 km (535 mi) northwest of the Cocos Islands. In October 2020, Australia's Bureau of Meteorology (BOM) issued its tropical cyclone outlook for the 2020–21 season, and in the same month, the agency contributed towards the Southwest Pacific Tropical Cyclone Outlook, along with New Zealand's MetService, NIWA and the Fiji Meteorological Service (FMS). On Wednesday morning, the low was around 2,700 km to the northwest of the Australian mainland, out past the Cocos (Keeling) Islands. The Bureau of Meteorology (BOM) says it expects Queensland's first cyclone this season will form by Sunday afternoon in the Gulf of Carpentaria, near the Northern Territory-Queensland border. In its latest outlook, the system had between a five and 20 per cent chance of becoming a tropical cyclone on Thursday or Friday. There were only 3 tropical cyclones, of which only one caused any damage. [59] Maximum wind gust speeds recorded on the mainland included 67 km/h (42 mph) at Port Hedland;[60] 65 km/h (40 mph) in Warburton;[61] 63 km/h (39 mph) at Lombadina;[62] 61 km/h (38 mph) at Giles and Telfer,[63][64] 59 km/h (37 mph) at Christmas Creek;[65] 56 km/h (35 mph) at Broome, Curtin, Derby and Barimunya,[66][67][68][69] 54 km/h (34 mph) at Karratha and Marble Bar;[70][71] 52 km/h (32 mph) at Roebourne;[72] and 50 km/h (31 mph) at Mandora. They also predicted that the Western and Northwestern sub-regions both had a 63% chance of experiencing more tropical cyclones than usual, the Northern region had a 57% chance of above average activity, and the Eastern region had a 67% chance of more tropical cyclones than the average. In October 2020, Australia's Bureau of Meteorology (BOM) issued its tropical cyclone outlook for the 2020–21 season, and in the same month, the agency contributed towards the Southwest Pacific Tropical Cyclone Outlook, along with New Zealand's MetService, NIWA and the Fiji Meteorological Service (FMS). Should a tropical depression reach tropical cyclone strength within TCWC Jakarta's area of responsibility, it will be assigned the next name from the following list:[96][97]. [32], Tropical Low 02U soon assumed a southeastward course, steered by the influence of a subtropical ridge situated to the east. - domain.com.au. The outlook called for a reduced level of tropical cyclone activity in the early season, from November to January, but an increased level of activity in the late season, from February to April. [5], During mid to late November 2020, a moderate strength pulse of the Madden–Julian Oscillation (MJO) tracked eastwards across the equatorial Indian Ocean towards the Maritime Continent and Australian longitudes. [92] Troughton Island also experienced a gust of 95 km/h (59 mph) during a thunderstorm on 21 December. [37][38], Tropical Low 02U made landfall between Port Hedland and Whim Creek on the Pilbara coastline just after 03:00 UTC on 11 December. An average to slightly-above-average number of tropical cyclones are expected for the 2020–21 Australian tropical cyclone season (November–April). Western Australia: $1.6 billion: $1.2 billion: None: Damien: 3 – 9 February 2020: Category 3 severe tropical cyclone: 150 km/h (90 mph) 955 hPa (28.20 inHg) Western Australia: $6 million: $4.3 million: None: Harold: 1 – 11 April 2020: Category 5 severe tropical cyclone: 230 … In 2020 in the North Atlantic basin, all of the statistics fell well above listed, featuring a record-breaking 30 tropical storms, 13 hurricanes, and 6 major hurricanes, with an ACE total of 178. These conditions should result in about average number of tropical cyclones (TC) over the Australian Region, with about 9 expected and with 5 becoming severe tropical cyclones (STC). [54] The system moved inland over the following days, tracking in a generally south-southeasterly direction. Australia's Bureau of Meteorology (BoM) warned Tropical Cyclone Blake, the first cyclone of the 2019/2020 season, was located around 240 kilometres north of Broome and was moving southeasterly. The United States Joint Typhoon Warning Center (JTWC) and other national meteorological services including Météo-France will also monitor the basin during the season. [51] Environmental conditions around the system were conducive for intensification, with low vertical wind shear, good upper-level outflow and sea surface temperatures near 30 Â°C (86 Â°F). (AAP Image/Bureau of Meteorology. [57] Sustained winds also reached 56 km/h (35 mph) at Bedout Island on 8 December, with a peak gust of 67 km/h (42 mph),[58] and Rowley Shoals recorded maximum sustained winds of 52 km/h (32 mph) and gusts to 65 km/h (40 mph). [74][75][76][77], During mid December, favourable conditions from a pulse of the Madden–Julian Oscillation (MJO) located over the eastern Maritime Continent contributed to the re-formation of the monsoon trough over northern Australia. [16] Before any significant intensification could occur, however, the tropical low exited the Australian region on 30 November, passing into the area of responsibility of Météo-France's tropical cyclone warning centre in Réunion. [10] The Joint Typhoon Warning Center (JTWC) assessed environmental conditions as being only marginally conducive for tropical cyclogenesis, with good poleward outflow and sea surface temperatures near 30 Â°C (86 Â°F) being offset by the effects of moderate vertical wind shear. [40][41] Ten-minute sustained winds also reached 63 km/h (39 mph) on Legendre Island at 00:00 UTC. [20], Tropical Low 01U made its closest approach to the Cocos Islands on 27–28 November, passing a little more than 500 km (310 mi) to the west. [82][83][84] Around this time, the BOM estimated the tropical low's central atmospheric pressure to be 995 hPa (29.38 inHg). While vast areas of Australia are being impacted by bushfires, many cattle stations in northern WA are celebrating a wet start to 2020 with some reporting their best rain in two years. [80][81] The system soon assumed a southwestward track towards the Kimberley region. [82] Despite this, the tropical low's close proximity to land hindered intensification, and only limited development occurred before the system made landfall on 19 December near the Cambridge Gulf, between Wyndham and Kalumburu. Watch the gripping new drama series Your Honor now on Stan. [47][49], As the tropical low tracked southeastwards towards the coast, environmental conditions continued to improve, with sea surface tempertaures nearing 31 Â°C (88 Â°F) and the system maintaining a robust poleward outflow channel in the upper troposphere. [28][29] On 7 December, warm sea surface temperatures and strong diffluence in the upper troposhphere fuelled the development of deep convection around the system's low-level circulation centre. The Australian tropical cyclone season runs from November until April although the first one doesn't usually develop until mid-to-late December. Fiji has been warned to prepare for category-5 tropical Cyclone Yasa, which is expected to directly hit the Pacific Island state in coming days. Calls for Sydney NYE fireworks to be cancelled, Dad forced to isolate from his family inside their home over Christmas, Sydney COVID-19 cluster: Interactive graphics and Christmas restrictions explained, By Olivana Lathouris • Associate Producer, Villages flattened as Fiji smashed by Category Five storm Cyclone Yasa, Cyclone Yasa: Fiji braces as powerful storm reaches land. Once over water it gradually intensified reaching category 1 strength at 2pm AWST 6 February and was named Tropical Cyclone Damien. [87][88] By the following day, the tropical low became slow-moving over the southeastern Kimberley region, during which time a minimum atmospheric pressure of 992.5 hPa (29.31 inHg) was recorded at Halls Creek. [21][22] Increased winds, as well as occasional showers and thunderstorms, occurred across the islands while the system was located nearby. Near normal activity during the season was expected for Papua New Guinea and the Solomon Islands, while an elevated level of activity was expected in the Coral Sea and the northern Tasman Sea, especially during the late season. The agency predicted a 66% chance of above average activity for the region as a whole, compared with the average of 11 tropical cyclones. [17] The system later intensified into Severe Tropical Storm Bongoyo in the South-West Indian Ocean cyclone region on 7 December. [28] After tracking in a clockwise path around the northeastern side of Christmas Island, Tropical Low 02U became quasi-stationary on 8 December. Each of the outlooks accounted for analogue seasons and the effects of various climate drivers, which included the state of the El Niño Southern Oscillation(ENSO). [35][36] This enabled the system to strengthen as it rapidly approached the coast of Western Australia at a speed of approximately 40 km/h (25 mph), although vertical wind shear once again began to increase. HMAS Adelaide will leave Brisbane on Thursday as the federal government provides $4.5 million to help the island neighbour recover from category five Tropical Cyclone … There were 4 tropical lows in total. The most recent cyclone to make landfall in Australia was Tropical Cyclone Esther, the third to cross the Australian mainland coast in the 2019/20 season, when it made landfall near the NT/Queensland border as a category 1 in February. The storm crossed the coast on the 21 of May, the latest known date of landfall for a tropical cyclone in Australia. Each of the outlooks accounted for analogue seasons and the effects of various climate drivers, which included the state of the El Niño Southern Oscillation (ENSO). [23] Maximum 10-minute sustained winds of 39 km/h (24 mph) with gusts to 46 km/h (29 mph) were observed at the airport on West Island at 04:30 UTC on 27 November. The PPA issued its first cyclone warning at 8am Perth time on Thursday as a tropical low lurked 740 kilometres south east of Christmas Island and approached the Australian mainland. A tropical low formed over land in the Kimberley, about 190km southeast of Kununurra on 3 February 2020 before tracking west. Australia has an average of 12 cyclones during the cyclone season however of those only about four make landfall. The season officially began on 1 November 2020 and will end on 30 April 2021, however, a tropical cyclone could form at any time between 1 July 2020 and 30 June 2021 and would count towards the season total. Tropical cyclones that develop between the Equator and 11°S, between the longitudes 151°E and 160°E, are assigned names by the tropical cyclone warning centre in Port Moresby, Papua New Guinea. Responsible for the sinking, & hence rapid breaking-up, of the MV Korean Star (1984) near Cape Cuvier on the 20th May. The 2020-21 Australian Region cyclone season was one of the least active seasons in Australian cyclone history. Australian and New Zealand researchers develop a new predictive model that forecasts cyclones up to four months in advance, which could buy the … Similarly, if a tropical cyclone is named in the Australian region and then moves into a neighbouring region, the Australian name will continue to be used. The system reaches tropical cyclone strength, it will become the first tropical cyclone of our 2020/21 season and be named Imogen. The La Nina weather pattern responsible for days of torrential rain, high winds and flooding on the east coast could fuel damaging tropical cyclones this summer. Sun 13 Dec 2020 20.24 EST First published on Sun 13 Dec 2020 16.29 EST. [55][56], The tropical low and associated thunderstorms generated strong winds in coastal and inland areas of the Kimberley and Pilbara regions as it tracked through the area, including sustained winds near gale force at several offshore sites. [96] These warning centres monitor all tropical cyclones that form within the Australian region, including any within the areas of responsibility of TCWC Jakarta or TCWC Port Moresby. [11] Consequently, the tropical low was expected to have only a low chance of developing into a tropical cyclone prior to moving westwards out of the Australian region later in the week. The season officially runs from November 1, 2020 to 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. Australian tropical cyclone outlooks. Firstly, it's located way out in the Indian Ocean. The 2020–21 Australian region cyclone season is the period of the year when tropical cyclones form in the Southern Indian Ocean and Pacific Oceans between 90°E and 160°E. September's TCO-AU guidance suggests normal to above normal risk for Australia for the coming tropical cyclone season (November 2020—April 2021). More cyclones than normal likely for Queensland due to La Niña. During the season, tropical cyclones will be officially monitored by one of the three tropical cyclone warning centres (TCWCs) for the region which are operated by the Australian Bureau of Meteorology, National Weather Service of Papua New Guinea and the Indonesian Agency for Meteorology, Climatology and Geophysics. "The BoM are monitoring a tropical load that's in the western region, it's fairly far away from Australia at the moment," BoM meteorologist Joel Pippard told nine.com.au. [6][7] The presence of the MJO brought an increase in tropical moisture to the atmospheric environment, as well as aiding the formation of Tropical Cyclone Alicia in the South-West Indian Ocean region in mid November. The Bureau of Meteorology (BoM) is monitoring a low pressure system that may develop into a tropical cyclone inside Australia's area of responsibility in the coming days. [73], As the sprawling tropical low tracked inland, flood watches and warnings were issued for large swathes of the deserts of western central Australia, incorporating parts of Western Australia, the Northern Territory and South Australia. [25], On 6 December 2020, the Bureau of Meteorology (BOM) reported that a tropical low had developed within a monsoon trough near the western end of Java, approximately 200 km (125 mi) north-northeast of Christmas Island. [26][27] The system was assigned the official identifier code 02U upon formation. Tom Saunders said: “Australia’s severe weather season (SWS) will see a wet La Niña-induced summer for the first time in nine years, increasing the risk of cyclones, flooding and thunderstorms. To improve your experience. Below average sea surface temperatures in the eastern tropical Pacific Ocean and atmospheric conditions indicated a La Niña pattern, and it was declared that a La Niña had emerged on 29 September 2020. The next 12 names on the naming list are listed below: The tropical cyclone warning centre in Jakarta monitors tropical cyclones from the Equator to 11°S, between the longitudes 90°E and 145°E. An average Atlantic hurricane season features 12 tropical storms, 6 hurricanes, and 3 major hurricanes, and features an Accumulated Cyclone Energy (ACE) count of 106. [32][33] By 12:00 UTC on 10 December, the system had begun to accelerate towards the southeast, moving into an environment more favourable for intensification. The Bureau of Meteorology (BoM) is monitoring a low pressure system that may develop into a tropical cyclone inside Australia's area of responsibility in the coming days. [80] Environmental conditions were favourable for tropical cyclogenesis, with low to moderate vertical wind shear, good upper-level outflow and very warm sea surface temperatures nearing 31 °C (88 °F). How the La Niña weather event could affect Australia for the rest of 2020. [26] Initially located in an unfavourable environment for intensification, the tropical low began to encounter somewhat improved conditions as it tracked towards the southeast. Below average sea surface temperatures i… The low moved offshore, near the Dampier Peninsula, north of Broome during 5 February. If a cyclone severely impacts the coast, resulting in significant damage and potentially loss of life (e.g. [13] On 29 November, the tropical low began to be steered slowly towards the west-northwest on the northern side of the subtropical high pressure belt. Despite tracking over land, the tropical low showed signs of organisation, with the generally favourable atmospheric conditions allowing the development of formative convective banding in the system's southern semicircle. [34][35] The interaction with an upper-level trough enhanced the tropical low's poleward outflow channel, allowing deep convection to rebuild over the centre of the system. [33] During this period, the JTWC reported that the tropical low's one-minute sustained winds had decreased to approximately 65 km/h (40  mph), from the earlier peak of 85 km/h (50 mph). Tropical Cyclone Damien as it crosses the coast of Western Australia’s Pilbara region, February 8, 2020.

[94] Upon entering the region, the system was classified as a tropical low by the Bureau of Meteorology (BOM), and had an estimated central atmospheric pressure of 1006 hPa (29.71 inHg). of the season could be forming in Australian waters but experts say it could come and go without hitting land. [49] Due to the system's proximity to the coast, however, both the BOM and the Joint Typhoon Warning Center (JTWC) forecast only a low chance of development into a tropical cyclone before making landfall. [78] On 17 December, a low-pressure system developed within the monsoon trough, near the northern coast of the Top End, and began to move westwards. The 2019–20 Australian region cyclone season was a below average tropical cyclone season for the waters surrounding Australia between longitudes 90°E and 160°E.The season officially began on 1 November 2019 and ended on 30 April 2020; however, tropical cyclones can form at any time of year, as evidenced by Tropical Cyclone Mangga during May 2020. [52] As the system strengthened in the moderately favourable environment, the BOM estimated the minimum atmospheric pressure at the centre of the low to be 997 hPa (29.44 inHg) at 18:00 UTC on 8 December. Tropical cyclone formation in this area is rare, and no cyclones have been named in it since 2007. [1][2] The bureau also advised that cyclone kits include a supply of face masks and hand sanitisers, owing to the concurrent COVID-19 pandemic. Your web browser is no longer supported. [43][44] Despite tracking over land, the BOM indicated that sustained winds to gale force, accompanied by gusts of up to 100 km/h (60 mph), could still occur near the centre of the system, particularly on the eastern side. Australian sailors will embark on a Christmas eve humanitarian mission to help thousands of people in cyclone-struck Fiji. If the low does reach tropical cyclone strength inside our region, it will become the first tropical cyclone of our 2020/21 season and be named Imogen. Image: The area of cloud inside the green circle has the potential to become Australia's frist tropical cyclone of the 2020/21 season. [34] The tropical low continued rapidly inland across Western Australia over the next day, accelerating to about 50 km/h (30 mph) soon after landfall. [3], The BOM expected an average to slightly above average number of tropical cyclones for the season. ", "There is a small chance it will turn into a tropical cyclone.". [89][90], Tropical Low 03U generated strong winds in the Kimberley region and on nearby islands for several days while located nearby. [37] Sustained gale-force winds were observed at Bedout Island and Port Hedland around the time of landfall, peaking at 70 km/h (43 mph) at both locations. "At the moment it's a cluster of thunderstorms, that is expected to gain a bit of structure over the next 24 to 72 hours. The 2020–21 Australian Region Cyclone Season is the period of the year when most tropical cyclones form within the Southern Indian Ocean and Pacific Oceans between 90°E and 160°E. [19] Satellite scatterometer data revealed maximum sustained winds of approximately 45 km/h (30 mph) at 02:30 UTC on 30 November, a few hours prior to the system exiting the Australian region. Heavens open over NSW unleashing wild storms. The average Atlantic hurricane season starts on June 1 and ends on November 30. [8][9] The system was assigned the identifier code 01U by the BOM. They attributed the strong winds on the eastern side of the system to a combination of enhanced northwesterly monsoonal flow and the system's fast translational velocity, rather than the low having intensified into a tropical cyclone. Maximum 10-minute sustained winds of 57 km/h (35 mph) with a gust to 72 km/h (45 mph) were observed on Browse Island,[91] and Adele Island recorded sustained winds of 54 km/h (34 mph) with a gust to 69 km/h (43 mph). Property News: When it comes to a partner's annoying home habits, should we live and let live? [78] The combined influence of the MJO and the monsoonal conditions generated widespread cloudiness and rainfall across the Australian tropics, leading to an increased likelihood of tropical cyclone formation in the region. Australian region tropical cyclone warnings, forecasts, seasonal outlooks, cyclone history, climatology and related information [24] A total of 23.6 mm (0.93 in) of rainfall was also recorded on 24–28 November. 2020-21 Australian Region cyclone season The BOM predicted that the La Niña pattern will persist into early 2021, and waters north of Australia and the Southwestern Pacific Ocean will be warmer than average in the coming three months. Mon 6 Jan 2020 03.04 EST. Retiring a cyclone name. Environmental conditions remained only marginally favourable for development, however, and the system's deep convection became displaced to the southwest of the centre due to northeasterly vertical wind shear, leaving the low-level circulation centre fully exposed. [10][11], Deep convection persisted over the system as the tropical low tracked gradually southwards over the following days, and by early 27 November, a curved convective rainband had developed on the eastern side. But before panicking, there are a few important things to know about this system. [30][31] Deep convection continued to develop near the centre during the overnight period, and as the low began to track eastwards, the JTWC upgraded the system to a tropical storm on the Saffir-Simpson hurricane wind scale at 18:00 UTC on 8 December. [79] The Bureau of Meteorology (BOM) classified the system as a tropical low by 06:00 UTC the following day while it was located near the Tiwi Islands, and assigned the identifier code 03U. [1] The Northwestern sub-region had a probability of two tropical cyclones crossing the Western Australian coast, with a significant risk of at least one of these to be a severe tropical cyclone. Weather 4:40pm Sep 29, 2020 'Zombie' Tropical Storm Paulette returns from the … [39] About three hours prior to landfall, the JTWC reported that maximum one-minute sustained winds had increased to 75 km/h (45 mph). [43][46], The presence of the Madden–Julian Oscillation and an equatorial Rossby Wave in the Australian region contributed to the formation of another broad low-pressure system in the monsoon trough over the far eastern Indian Ocean during early December. [4], The Southwest Pacific Tropical Cyclone Outlook covered a portion of the Australian region that comprised waters surrounding Papua New Guinea, the Solomon Islands, the Coral Sea, and the northern Tasman Sea including Norfolk Island. [93], On 20 December 2020, a tropical disturbance that was being monitored by Météo-France's tropical cyclone warning centre in Réunion crossed into the Australian region from the South-West Indian Ocean basin. The severe multi-year drought across the eastern states is being subdued in 2020 as rain begins to replenish the dry land and empty dams. [42] Despite these wind readings, the BOM did not classify the low as a Category 1 tropical cyclone because they determined that gale-force winds did not extend more than halfway around the centre. 1 Seasonal Summary 2 Systems 2.1 Tropical Cyclone Kimi 2.2 Tropical Low 02U 2.3 Tropical Cyclone Lucas 2.4 Tropical Cyclone Alu 2.5 Tropical Low 05U 2.6 Tropical Low 06U 2.7 Severe Tropical Cyclone Marian 2.8 Tropical Cyclone Niran 2.9 Tropical Low 09U 2.10 Severe Tropical Cyclone Buri 2.11 Tropical Low 11U 2.12 Tropical Cyclone Odette 2.13 Severe Tropical Cyclone Paddy 2.14 … [49] Owing to the increase in organisation, the Bureau of Meteorology (BOM) classified the system as a tropical low by 21:00 UTC,[50] when it was located approximately 330 km (205 mi) northwest of Broome. Neutral conditions are expected through the 2019/2020 Australian tropical cyclone season. Forecast models suggest the system will move south and then west away from our continent. News Royal Australian Navy heads to cyclone-hit Fiji on humanitarian mission 11:08pm, Dec 23, 2020 Updated: 11:43pm, Dec 23 The satellite image of Cyclone Yasa over Fiji on December 17. Individual cyclone reports These reports have mainly been compiled using original material produced soon after the cyclone … "There's absolutely no threat to the mainland but the Coco Islands might get increased winds and rains," Mr Pippard said. [14][15] The system encountered somewhat weaker wind shear along its new track, allowing deep convection to develop closer to the low-level circulation centre. The system reaches tropical cyclone strength, it will become the first tropical cyclone of … Read the detailed post cyclone reports for Australian cyclones dating back to 1970.
