Tropical Low 21U

20 - 26 March 2021
Best Track of Tropical Low 21U


Tropical Low 21U formed on 20 March near the Cocos (Keeling) Islands and moved towards the west. The low had no impact on the islands as it went past. As the low moved west it gradually intensified and gales were recorded in the southeast quadrant for a period on 23 March. Conditions were not favourable for further development and tropical low 21U never attained tropical cyclone intensity. From 24 March the low weakened and slowly moved northwest, leaving the Australian Region on 27 March.
