Tropical Cyclone Koji

5-8 March 2012


Tropical Cyclone Koji was the fourth tropical cyclone to form in the Western Region. A tropical low pressure system formed during an active phase of the Madden-Julian Oscillation (MJO) near 10.4°S 101.3°E on 5 March and tracked towards the southwest, passing more than 200 kilometres (km) to the south of the Cocos Keeling Islands and having no impact on the group of islands. The tropical low reached tropical cyclone intensity late on 7 March and began moving rapidly westwards. Just prior to crossing into La Reunion's area of responsibility (AOR) on 8 March Koji reached Category 2 intensity. The tropical cyclone was renamed Koji-Joni and continued to track westwards and intensify before weakening below tropical cyclone strength on 13 March in the central Indian Ocean.
