During the year, a total of 146 tropical cyclones had formed. 88 tropical cyclones had been named by either a Regional Specialized Meteorological Center (RSMC) or a Tropical Cyclone Warning Center (TCWC). The strongest and deadliest tropical cyclone was Hurricane Maria with a minimum barometric pressure of 908 mbar and killing 3,000 people in Puerto Rico and Dominica. The costliest tropical cyclone of the year was Hurricane Harvey in the Atlantic, which struck Houston metropolitan area in August causing US$125 billion in damage, tying with Hurricane Katrina as the costliest tropical cyclone worldwide.

Intense Tropical Cyclone Enawo was the strongest tropical cyclone of the 2016–17 South-West Indian Ocean cyclone season. Enawo was the strongest tropical cyclone to strike Madagascar since Gafilo in 2004, killing 78 people and causing $400 million in damages. Forming as a moderate tropical storm on 3 March, Enawo initially drifted and intensified slowly. It strengthened into a tropical cyclone on 5 March and further an intense tropical cyclone on 6 March. Enawo made landfall over Sava Region on 7 March just after reaching peak intensity, and it emerged back into the Indian Ocean as a post-tropical depression late on 9 March, before dissipating two days later. The most severe impacts were seen in the districts of Antalaha and Maroantsetra.
