The Joint Typhoon Warning Center (JTWC) estimated peak 1 minute sustained winds of 120 km/h (75 mph), while the India Meteorological Department (IMD) estimated peak 3 minute sustained winds of 100 km/h (60 mph); the IMD is the official warning center for the north Indian Ocean.

After peaking, it weakened due to wind shear, dry air, and cooler waters, and the JTWC issued its final advisory on December 3 as it approached the coast of Somalia.

A tropical disturbance was observed on November 19 about 800 km (500 mi) southeast of Colombo, Sri Lanka in the Bay of Bengal.

[1] The disturbance tracked westward, gradually organizing and prompting the JTWC to issue a Tropical Cyclone Formation Alert (TCFA) on November 22.

[14] After reaching peak intensity, an increase in wind shear caused the eye to disappear,[15] and the convection decreased significantly.

[24] It turned southwestward and later to the south, moving ashore on eastern Somalia before dissipating on December 5 near Ceel Huur over water.

[25][26] However, according to RSMC La Réunion, the precursor low to Cyclone Agni briefly moved into the Southern Hemisphere and kept its anticyclonic counter-clockwise circulation.
