Tropical cyclone Corentin was the first named tropical cyclone of 2016 in the South Indian Ocean. Corentin caused little danger because it's genesis, maturation and dissipation have all occurred over the South Indian Ocean about equidistant from the distant shores of Madagascar and Australia. The GPM core observatory satellite flew over Tropical Cyclone Corentin on January 25, 2016 at 1306 UTC. High vertical wind shear was starting to take it's toll on the increasingly disorganized tropical cyclone. Rainfall collected by GPM Microwave Imager (GMI) and Dual-frequency Precipitation Radar (DPR) instruments showed that Corentin still contained some moderate to heavy rainfall in bands southeast of the exposed center of low level circulation. GPM's DPR measured precipitation falling at rates of up to 78.5 mm (3.1 inches) per hour in that area.

3-D measurements by GPM's Radar (DPR Ku band) showed that most storm tops in the elongated tropical cyclone were reaching heights of less than 7 km (4.3 miles).
