At 1200 UTC on November 30, the IMD issued its first complete advisory on the cyclone, naming it Severe Cyclonic Storm Agni and estimating peak winds at 100 km/h (60 mph); the agency predicted the storm would continue northwestward and strengthen slightly before weakening. At its peak, the cyclone had a

By late on December 3, Agni weakened to below tropical storm status, and the JTWC issued its final warning while the storm was about 450 km (275 mi) south-southeast of

November 28. Three hours later, the agency classified the system as Tropical Cyclone 05A about 1300 km (800 mi) southwest of the southern tip of India. In a post-season analysis, the JTWC estimated the cyclone became a tropical storm six hours earlier. At around the same time, the

After reaching peak intensity, an increase in wind shear caused the eye to disappear, and the convection decreased significantly. On
December 1, the IMD estimated Agni weakened to cyclonic storm status, around which time the center became exposed from the convection. The cyclone continued its
