This was the second time that a tropical Cyclone had formed during the month of July. The other one was Cyclone Lindsay in the 1996–1997 season. The next cyclone that formed was Cyclone Guba

In April 2008 Tropical Cyclones Rosie and Durga were the first ever Tropical Depressions to be monitored within TCWC Jakarta's area of responsibility and Durga was also the first storm to reach Tropical cyclone status and named whilst being monitored by TCWC Jakarta. Durga was also the last storm of the season which officially ended on 30 April.

Tropical Cyclone 01U

On 29 July an area of low pressure close to the edge off RSMC La Reunions Area of responsibility, was designated as Tropical Disturbance 01R, by the RSMC in La reunion. However this number was withdrawn in RSMC La reunions post storm Analysis. The JTWC issued a Tropical Cyclone Formation Alert (TCFA) on the developing system on 29 July and initiated warnings on the tropical cyclone late that day designating it as Tropical cyclone 01S. However by this time the cyclone had crossed 90E and had crossed into TCWC Perth's Area of Responsibility, who designated it as a Tropical Low and issued shipping warnings on the Tropical Low. Early on 30 July The Cyclone began to dissipate so the JTWC issued their final advisory that day. and the Bureau of Meteorology issued its last warning the next day.

During Post storm analysis The Bureau of Meteorology upgraded the Tropical low to a tropical cyclone in its post-storm analysis, with maximum 10-min sustained winds of 75 km/h (45 mph) based on QuikSCAT
