During 17 November a low formed during an active phase of the Madden-Julian Oscillation (MJO) along the monsoon trough in the central Indian Ocean. The low developed quickly and was upgraded to Tropical Cyclone (TC) Anika at 0000 UTC (0900 WDT) 19 November. Anika moved on a steady east southeast path, passing to the northeast of the Cocos Islands. The system reached category 2 intensity early on 20 November before rapidly weakening later that day. Anika was downgraded to a tropical low at 0000 UTC (0900 WDT) 21 November as it moved over cooler seas surface temperatures and was affected by increased wind shear caused by the approach of a mid-level trough.
Anika was the first tropical cyclone of the Australian 2008/09 tropical cyclone season.
