The season was also the costliest recorded in the Australian region basin, with a total of $3.62 billion (2011 USD) in damages, mostly from the destructive Cyclone Yasi.Reuters 3 February 2011 5 November 2011 Cyclone Yasi to cost insurers A$3.5 billion – forecaster https://www.reuters.com/article/insured-losses-yasi-idUSLDE7121NR20110203 The season began on 1 November 2010 and ended on 30 April 2011, although the first tropical cyclone formed on 28 October. The Australian region is defined as being to the south of the equator, between the 90th meridian east and 160th meridian east. Tropical cyclones in this area are monitored by five Tropical Cyclone Warning Centres (TCWC's): Jakarta, Port Moresby, Perth, Darwin, and Brisbane, each of which have the power to name a tropical cyclone. The TCWC's in Perth, Darwin, and Brisbane are run by the Bureau of Meteorology, who designate significant tropical lows with a number and the U suffix. The Joint Typhoon Warning Center also issues unofficial warnings for the region, designating significant tropical cyclones with the "S" suffix when they form west of 135°E, and the "P" suffix when they form east of 135°E. __TOC__ Seasonal forecasts TSR forecastsDate Tropicalstorms Severe Tropicalcyclones Landfallingcyclones ACE Ref Average (1975/76–2009/10) 10.5 5.5 4.5 79 5 May 2010 Lea, Adam Extended Range Forecast for Australian-Region Tropical Storm Activity in 2010/11 Tropical Storm Risk Consortium https://www.tropicalstormrisk.com/docs/TSRAUSForecastMay2010.pdf 5 May 2010 Saunders, Mark6 December 2010 Lea, Adam December Forecast Update for Australian-Region Tropical Storm Activity in 2010/11 Tropical Storm Risk Consortium https://www.tropicalstormrisk.com/docs/TSRAUSForecastDec2010.pdf 6 December 2010 Saunders, Mark 5 May 2010 9.3 4.9 4 – 6 July 2010 12.5 6.7 5.2 – 6 July 2010 Lea, Adam July Forecast Update for Australian-Region Tropical Storm Activity in 2010/11 Tropical Storm Risk Consortium https://www.tropicalstormrisk.com/docs/TSRAUSForecastJul2010.pdf 6 July 2010 Saunders, Mark 6 September 2010 15.1 8.1 6.1 108 6 September 2010 Lea, Adam September Forecast Update for Australian-Region Tropical Storm Activity in 2010/11 Tropical Storm Risk Consortium https://www.tropicalstormrisk.com/docs/TSRAUSForecastSep2010.pdf 6 September 2010 Saunders, Mark 9 November 2010 15.4 8.3 6.2 111 9 November 2010 Lea, Adam November Forecast Update for Australian-Region Tropical Storm Activity in 2010/11 Tropical Storm Risk Consortium https://www.tropicalstormrisk.com/docs/TSRAUSForecastNov2010.pdf 9 November 2010 Saunders, Mark 6 December 2010 15.5 8.3 6.2 111 Region Average Chance ofAbove average Predictedactivity Actual activity Ref Whole 12 98% 20–22 10 Western 7 93% 11–12 6 North-Western 4 67% 5 5 Northern 6 75% 7–8 0 Eastern 4 87% 6–7 4 ForecastCenter Tropicallows Tropicalcyclones Severe tropicalcyclones Ref Actual activity: BoM 28 10 5 Actual activity: JTWC 13 13 5 Ahead of the cyclone season, the Bureau of Meteorology (BoM), the New Zealand National Institute of Water and Atmospheric Research (NIWA) and various other Pacific Meteorological services, all contributed towards the Island Climate Update tropical cyclone outlook that was released during October 2010.National Institute of Water and Atmospheric Research http://www.niwa.co.nz/climate/icu/island-climate-update-121-october-2010/sw-pacific-tc-guidance-for-the-2010-11-season Island Climate Update SW Pacific TC guidance for the 2010–11 season 26 November 2010 16 November 2014 29 November 2014 https://web.archive.org/web/20141129154137/http://www.niwa.co.nz/climate/icu/island-climate-update-121-october-2010/sw-pacific-tc-guidance-for-the-2010-11-season live The outlook took into account the moderate-strong La Niña conditions that had been observed across the Pacific and analogue seasons that had La Niña conditions occurring during the season.National Institute of Water and Atmospheric Research http://www.niwa.co.nz/news/zelia-consistent-tropical-cyclone-outlook Zelia consistent with tropical cyclone outlook NIWA 11 January 2015 18 January 2011 16 November 2014 https://web.archive.org/web/20150111223408/http://www.niwa.co.nz/news/zelia-consistent-tropical-cyclone-outlook live The outlook called for a normal or above average number of tropical cyclone occurring during the season, with nine to twelve named tropical cyclones, to occur between 135°E and 120°W compared to an average of nine. At least three of the tropical cyclones were expected to become category 3 severe tropical cyclones, while one was expected to become a category 4 severe tropical cyclone. In addition to contributing towards the Island Climate Update outlook, the BoM issued seven seasonal forecasts during October 2010, for the Australian region and the Southern Pacific with each forecast covering the whole tropical cyclone year.2010–2011 Australian tropical cyclone season outlook National Climate Centre https://www.bom.gov.au/climate/ahead/archive/tropical-cyclone/2010-2011-tc.shtml Australian Bureau of Meteorology 11 January 2015 18 October 2010 Each forecast issued took into account the La Niña conditions that had developed over the region and were forecasted to persist during the season.

On 30 October, the JTWC began issuing advisories on the system, designating it as Tropical Cyclone 02S. The next day, TCWC Jakarta reported that the low had intensified into a category 1 tropical cyclone on the Australian scale, naming it "Anggrek". Later that day, as the system moved towards the southeast, it entered the BoM's area of responsibility as it further intensified into a category 2 tropical cyclone. Anggrek passed to the east of the Cocos (Keeling) Islands early on 2 November, with the system beginning a weakening trend soon afterwards. On 4 November, TCWC Perth issued the final advisory on the system as Anggrek weakened into a tropical low. The next day, the remnants of Anggrek entered the south-west Indian Ocean as a convective-less circulation center.Météo-France Bulletin for Cyclonic Activity and Significant Tropical Weather in the Southwest Indian Ocean 5 November 2010 8 December 2015 http://www.meteo.fr/temps/domtom/La_Reunion/webcmrs9.0/anglais/archives/bulletins/zcit/20102011/ZCITA_201011051000.html Throughout the Cocos (Keeling) Islands, heavy rain and gusty winds were experienced as Cyclone Anggrek passed. Only minor damage was reported, with several trees and power lines brought down. No deaths were reported across the islands. Operationally, Anggrek peaked as a minimal tropical cyclone, however, in TCWC Perth's post-season analysis, Anggrek was downgraded to a tropical low as gale-force winds never extended more than halfway around the system center.

The system drifted slowly to the south-east. Gales and heavy rain reached areas far from the centre of the system which crossed the coast near Coral Bay on 18 December. However, shortly after landfall the system turned sharply to the south-west and reached the Indian Ocean west of Carnarvon on 19 December. It moved away from the coast and dissipated late on 20 December some 500 km west of Geraldton. In the catchment basin of the Gascoyne River heavy precipitation fell from 16 to 19 December and triggered one of the worst floods along the Gascoyne River in history. The rain also affected other river basins in the area, such as Wooramel, Murchison, Lyndon-Minilya, and Ashburton rivers. For the period from 16 to 20 December some stations reported up to 300 mm cumulated precipitation which is equivalent to the normal annual rainfall amount. The highest 24 hours rainfall was reported at Carnarvon Airport on 17 December. During that day 207.8 mm fell which set an all-time record since recording began in 1883 with the previous record 119.4 mm set on 24 March 1923. Preliminary estimates placed damage at A$100 million (US$100.4 million) with at least 2000 head of cattle lost in the flood.http://www.bom.gov.au/wa/sevwx/gascoyne_river/gascoyne_river.shtml Bureau of Meteorology Gascoyne River Flood 2010 21 January 2011 https://web.archive.org/web/20110111084027/http://www.bom.gov.au/wa/sevwx/gascoyne_river/gascoyne_river.shtml 11 January 2011 dead Tropical Cyclone Tasha 2010–2011 Queensland floods Aus 20 December 25 December Tasha dec 25 2010 0040Z.jpg Tasha 2010 path.png 40 40 993 Tropical Cyclone Tasha was first identified on 24 December 2010 by the Joint Typhoon Warning Centre (JTWC) as a weak area of low pressure accompanied by increasing deep convection.

The depression intensified into a Tropical Cyclone on 14 January, and given the named Zelia. It strengthened rapidly and became the first severe tropical cyclone of the season on 15 January. On 16 January, wind shear increased and cooler sea surface temperatures caused Zelia to weaken, as the system transitioned into a mid-latitude low as it passed east of Norfolk Island.

The JTWC subsequently initiated advisories on the system early on 23 January and designated it as Tropical Cyclone 09P, before TCWC Brisbane reported that the system had developed into a category 1 tropical cyclone and named it Anthony.JTWC Tropical Cyclone 09P Warning 01 http://weather.noaa.gov/pub/data/raw/wt/wtps32.pgtw..txt Joint Typhoon Warning Center 28 January 2011 dead https://web.archive.org/web/20101203124421/http://weather.noaa.gov/pub/data/raw/wt/wtps32.pgtw..txt 3 December 2010 During that day the system may have become a category 2 tropical cyclone as radar and microwave imagery showed that Anthony had a well defined circulation and was forming a partial eyewall. The system subsequently moved into an area of higher vertical windshear and weakened into a tropical low during 24 January as it moved into the South Pacific basin. The system moved back into the Australian region during 25 January but remained a tropical low over the next few days, as it moved north-westwards across the Coral Sea as a low level circulation centre with little or no associated convection. During 28 January TCWC Brisbane briefly reported that Anthony had re-intensified into a category 1 tropical cyclone, after wind shear over the system reduced due to a possible Fujiwhara interaction with a secondary circulation to the east of Anthony and Severe Tropical Cyclone Wilma. However, later that day the system turned and started moving towards the north-west as the secondary system moved to its north, which meant that Anthony became sheared again and weakened into a tropical low. The system remained a sheared tropical low until late on 29 January, when convection began to increase and organize as a result of weakening upper atmospheric wind shear. During the next day as Anthony moved towards the southwest and the Queensland coast, the JTWC re-initiated advisories on the system, before reporting that it had peaked with 1-minute sustained wind speeds of 100 km/h mph on 5.JTWC Tropical Cyclone 09P Warning 07 http://weather.noaa.gov/pub/data/raw/wt/wtps32.pgtw..txt Joint Typhoon Warning Center 28 January 2011 dead https://web.archive.org/web/20101203124421/http://weather.noaa.gov/pub/data/raw/wt/wtps32.pgtw..txt 3 December 2010 Tropical Cyclone 09P (Anthony) best track analysis United States Navy, United States Air Force http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/best_tracks/2011/2011s-bsh/bsh092011.dat 22 July 2012 Joint Typhoon Warning Centre https://web.archive.org/web/20120609020915/http://www.usno.navy.mil/NOOC/nmfc-ph/RSS/jtwc/best_tracks/2011/2011s-bsh/bsh092011.dat 9 June 2012 28 December 2011 dead TCWC Brisbane also reported that the system had re-intensified into a category 1 tropical cyclone during that day, before reporting that it had become a category 2 tropical cyclone with peak 10-minute sustained wind speeds of 100 km/h mph on 5.
