2020-21 Australian Region cyclone season 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. 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.  The tropical low made landfall on the Kimberley coast between Bidyadanga and the Anna Plains cattle station just after 00:00 UTC on 9 December. September's TCO-AU guidance suggests normal to above normal risk for Australia for the coming tropical cyclone season (November 2020—April 2021). On average, there are 9 to 11 tropical cyclones each season in the Australian region, four of which typically cross the coast. , On 20 December 2020, a tropical disturbance that was being monitored by MÃ©tÃ©o-France's tropical cyclone warning centre in RÃ©union crossed into the Australian region from the South-West Indian Ocean basin. ", "There is a small chance it will turn into a tropical cyclone.".  Despite this, the system remained mostly disorganised in the marginal environment, with an elongated low-level circulation centre. , Tropical Low 01U made its closest approach to the Cocos Islands on 27â28 November, passing a little more than 500 km (310 mi) to the west. 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. If a cyclone severely impacts the coast, resulting in significant damage and potentially loss of life (e.g. Australian region tropical cyclone warnings, forecasts, seasonal outlooks, cyclone history, climatology and related information Watch the gripping new drama series Your Honor now on Stan.  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 Â°C (88 Â°F). "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 system continued towards the southwest over the ensuing hours, paralleling the coast of Western Australia.  Owing to the increase in organisation, the Bureau of Meteorology (BOM) classified the system as a tropical low by 21:00 UTC, when it was located approximately 330 km (205 mi) northwest of Broome. Neutral conditions are expected through the 2019/2020 Australian tropical cyclone season. Australian tropical cyclone outlooks. Australian sailors will embark on a Christmas eve humanitarian mission to help thousands of people in cyclone-struck Fiji. , The BOM expected an average to slightly above average number of tropical cyclones for the season. 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). Bureau of Meteorology says cyclone off WA’s northern coast is likely to bring heavy rain and gale-force winds, First published on Mon 6 Jan 2020 00.42 EST. 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 …  Around this time, the BOM estimated the tropical low's central atmospheric pressure to be 995 hPa (29.38 inHg). In its latest outlook, the system had between a five and 20 per cent chance of becoming a tropical cyclone on Thursday or Friday. , Tropical Low 02U soon assumed a southeastward course, steered by the influence of a subtropical ridge situated to the east. Tropical cyclone formation in this area is rare, and no cyclones have been named in it since 2007. 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.  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.

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.  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. 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. 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. The system reaches tropical cyclone strength, it will become the first tropical cyclone of our 2020/21 season and be named Imogen. 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.  After reaching the Dampier Peninsula on 20 December, the system turned sharply to the east and began tracking further inland. To improve your experience. , 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.  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. How the La Niña weather event could affect Australia for the rest of 2020.  The system soon assumed a southwestward track towards the Kimberley region.  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.  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.  The system moved inland over the following days, tracking in a generally south-southeasterly direction. 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:.  Initially situated approximately 825 km (510 mi) west-northwest of the Cocos Islands, the system was located in an environment that was generally unfavourable for intensification, with moderate to strong vertical wind shear offsetting otherwise conducive upper-level outflow and warm sea surface temperatures of 28â29 Â°C (82â84 Â°F)..
