-'''Severe Tropical Cyclone Yasi''' {{IPAc-en|ˈ|j|ɑː|s|iː}} was a powerful and destructive [[tropical cyclone]] that made landfall in northern [[Queensland]], [[Australia]], causing major damage to the affected areas. Originating as a tropical low near [[Fiji]] on 26 January, the system intensified to [[Tropical cyclone scales|tropical cyclone status]] during the evening of 30 January 2011. Yasi underwent rapid deepening over the next 24 hours, with the storm classified as a Category 3 cyclone at about 5 PM [[Time in Australia|AEST]] (07:00 [[Coordinated Universal Time|UTC]]) on 31 January 2011.<ref name="qpmsc">{{Cite news | url=http://news.smh.com.au/breaking-news-national/qld-prepares-for-most-savage-cyclone-20110131-1aa14.html | title=Qld prepares for 'most savage' cyclone | accessdate=1 February 2011 | date=31 January 2011 | newspaper=[[The Sydney Morning Herald]] | publisher=[[Fairfax Media]] | agency=[[Australian Associated Press]] }}</ref> Late on 1 February, the cyclone strengthened to a Category 4 system; then, early on 2 February, the cyclone intensified into a Category 5 Severe Tropical Cyclone.<ref name="1febadvice">{{cite web | url=http://www.bom.gov.au/cgi-bin/wrap_fwo.pl?IDQP0005.txt | title=Tropical Cyclone Advice No. 9 | accessdate=1 February 2011  | date=1 February 2011 | work=[[Bureau of Meteorology]] | publisher=[[Australian Government]] }}</ref> The system had a well-defined [[Eye (cyclone)|eye]] and continued to track west-southwestward, maintaining a central pressure of 930 hPa (27 inHg) and a [[Dvorak intensity]] of T6.5 into the evening.<ref name="2febadvice">{{cite web |url=http://www.bom.gov.au/cgi-bin/wrap_fwo.pl?IDQP0005.txt |title=Tropical Cyclone Advice Number 21 |accessdate=2 February 2011 |date=2 February 2011 |work=Bureau of Meteorology | publisher=Australian Government}}</ref><ref>{{cite web |url=http://www.bom.gov.au/cgi-bin/wrap_fwo.pl?IDQ20018.txt|title=Tropical Cyclone Technical Bulletin |accessdate=2 February 2011 |date=2 February 2011 |work=Bureau of Meteorology | publisher=Australian Government}}</ref>

The storm caused an estimated AU$3.5 billion (US $3.6 billion) in damage, making it the costliest tropical cyclone to hit Australia on record (not accounting for inflation; otherwise, [[Cyclone Tracy]] was costlier).

-==Preparations, impact and aftermath==

-Severe Tropical Cyclone Yasi directly impacted the Solomon Islands, Vanuatu and parts of Australia, while parts of Fiji and Papua New Guniea were indirectly impacted. As a result of the system's impacts, the name Yasi was subsequently retired from the list of South Pacific tropical cyclone names and replaced with Yvone.{{RA V Tropical cyclone operational plan}}
-===Fiji, Vanuatu, Papua New Guniea and the Solomon Islands===
-Between January 23 - 30, strong winds and swells were observed in Tuvalu, in association with the development and passage of Tropical Cyclone’s Wilma and Yasi.<ref name="SWFDDP">{{cite report|publisher=World Meteorological Organization |title=Severe Weather Forecasting and Disaster Risk Reduction Full Demonstration Project (SWFDDP) Region Sub Project RA V Progress Report Number 1: For the period 1 October 2010&nbsp;– 28 February 2011|url=http://www.wmo.int/pages/prog/www/CBS-Reports/documents/PR1-11_RAV_SWFDDP_FullDemo_1st.pdf |accessdate=18 January 2018 |archivedate=18 January 2018|date=17 May 2011|archiveurl=https://www.webcitation.org/6LvBfCdtP?url=http://www.wmo.int/pages/prog/www/CBS-Reports/documents/PR7-13-RAV-SWFDDP-FullDemo_7th.pdf |deadurl=no |df= }}</ref><ref name="Vulnerability">{{cite report|title=Vulnerability profile of Tuvalu|archiveurl=https://www.webcitation.org/6wYOoEJW6|archivedate=8 July 2012|date=March 2012|accessdate=17 January 2018|publisher=United Nations Conference on Trade and Development|url=https://www.un.org/development/desa/dpad/wp-content/uploads/sites/45/vulnerability_profile_tuvalu_2012.pdf|format=PDF}}</ref> These strong winds delayed shipping schedules and affected students studying in Vaitupu and Fiji, while outer islands ran out of fresh supplies as a result of rough seas.<ref name="Vulnerability"/> During 28 - 30 January, Yasi's precursor tropical depression caused rain and strong winds over the Fijian islands off [[Rotuma]], [[Vanua Levu]], [[Taveuni]] and the northern [[Yasawa Islands]].<ref name="2011 ACS">{{cite report|author=Climate Services Division|title=Fiji Annual Climate Summary: 2011|archiveurl=https://www.webcitation.org/68zUpMfhE|archivedate=8 July 2012|date=19 June 2012|accessdate=17 January 2018|publisher=Fiji Meteorological Service|url=http://www.met.gov.fj/Summary2.pdf|format=PDF}}</ref>
-During January 30, the system subsequently became the second of three systems to directly impact Vanuatu within two months. Tropical Cyclone Yasi moved across Vanuatu's northern [[Torba Province]], with winds reaching up to 95&nbsp;km/h (60&nbsp;mph).<ref name=rnzi>{{cite news|first=|last=|title=Cyclone Yasi moves towards Australia |url=http://www.rnzi.com/pages/news.php?op=read&id=58510 |work=[[Radio New Zealand International]] |publisher= |date=2011-01-31 |accessdate=2011-02-03}}</ref> Vanuatuan officials reported difficulties making contact with the [[Torba Province]], but it was believed that the northern area escaped major damage.<ref name=rnzi2>{{cite news|first=|last=|title=Solomon Islands and Vanuatu appear to have avoided the worst of Cyclone Yasi |url=http://www.rnzi.com/pages/news.php?op=read&id=58539|work=[[Radio New Zealand International]] |publisher= |date=2011-02-02 |accessdate=2011-02-03}}</ref>
-Though the storm was situated several hundred kilometres southeast of [[Papua New Guinea]], the outer edges of the large system brought strong winds, high [[sea]]s and heavy [[rain]] to the country. In [[Milne Bay Province]], local officials advised residents living along the coast to move to higher grounds.<ref>{{cite web|author=Staff writer |work=[[Radio Australia]] |publisher=Australian Broadcasting Corporation |date=31 January 2011 |accessdate=1 February 2011 |title=PNG, Solomons alert for cyclone bhYasi |url=http://www.radioaustralianews.net.au/stories/201102/3127065.htm?desktop |archiveurl=https://web.archive.org/web/20110205025943/http://www.radioaustralianews.net.au/stories/201102/3127065.htm?desktop |archivedate=5 February 2011 |deadurl=yes |df=dmy }}</ref>
-===Willis Island===
-As Yasi moved into the Australian region meteorological data from the weather station on [[Willis Island (Coral Sea)|Willis Island]] was used to help monitor the system. Ahead of the system impacting the island, staff battened down the buildings and were evacuated off the island by a helicopter during 1 February.<ref>http://www.bom.gov.au/inside/eiab/reports/ar10-11/doc/Bureau_of_Meteorology_Annual_Report_2011.pdf</ref><ref name="WillisIsland1">{{cite news|publisher=Australian Broadcasting Corporation|date=2 February 2011|accessdate=18 January 2018|title=Monster cyclone knocks out weather radar|url=http://www.abc.net.au/news/stories/2011/02/02/3127757.htm|archiveurl=https://www.webcitation.org/6wYEjq7IT|archivedate=18 January 2018}}</ref> Yasi subsequently passed directly over the weather station during 2 January, where wind gusts of 185&nbsp;km/h (115&nbsp;mph) and a minimum pressure of {{convert|937.9|hPa|inHg|abbr=on}} were recorded, before the meteorological equipment and communications failed.<ref name="WillisIsland1"/> After the system passed over the island, it became clear that the strong winds and storm surge had damaged the radar, key observing systems as well as communications, operational and life support infrastructure. It was also noted that the system had altered the shape of the island and cleared most of its vegetation. Most of the automated surface observing systems and communications were subsequently restored and became operational, fifteen days after Yasi had passed over the island. However, the radar and life-supporting systems took a bit longer to restore and were subsequently completed by the end of November, before staff returned to the island during December 2011.<ref name="BOM20111212">{{Cite press-release|url=http://www.bom.gov.au/announcements/media_releases/qld/20111212.shtml|title=Back to business for Willis Island weather station|deadurl=no|archiveurl=https://www.webcitation.org/6wYGb5xG8|archivedate=18 January 2018|publisher=Australian Bureau of Meteorology|date=12 December 2011}}</ref>

-By the time Yasi crossed into Australian basin, preparations for the [[storm]] were under way.
