Several areas of convection persisted within the ITCZ in early March across the open Indian Ocean. One of these organized into a tropical storm on March 2 about 700 km (430 mi) south of Diego Garcia and was given the name Daodo. On the following day, the JTWC began tracking it as Tropical Cyclone 21S. Daodo moved slowly initially while quickly strengthening into a severe tropical storm. On March 4, a weak ridge steered the storm to the east, and the storm weakened slightly during this time. Three days later a stronger ridge to the east turned Daodo to the southwest, bringing it over its former path. On March 8, the JTWC upgraded the storm to the equivalent of a minimal hurricane. On the following day, the MFR upgraded Daodo to tropical cyclone status, estimating peak 10 minute winds of , although it weakened back into a tropical storm on March 10. The storm accelerated to the southeast on the next day and maintained much of its intensity due to baroclinic interactions with a nearby anticyclone. On March 13, Daodo turned back to the southwest before moving more southward and later to the southeast. On March 18, the storm dissipated within a polar trough northwest of Île Amsterdam.
