Summary
Tropical Cyclone Robyn was an early season, short lived cyclone in the Indian Ocean.
A tropical low (designated AU202425_01U) formed southwest of Sumatra associated with MJO and Kelvin wave activity. The development of a broad low was very gradual as it was constrained by northeasterly vertical wind shear.
The low moved southwest into the Australian region of responsibility (south of 10°S) on 27 November. The wind shear decreased, and Robyn reached tropical cyclone intensity early on 28 November, peaked briefly at category 2 intensity late on 28 November before weakening rapidly on 29 November. The remnant circulation then turned to the west and passed west of 90°E out of the Australian region during early December.
The system passed initially to the north then west of Cocos Islands and had no direct impact on the islands.
