List of South-West Indian Ocean tropical cyclones

Within the South-West Indian Ocean, the term tropical cyclone is reserved for those systems, that have winds of at least 65 knots (120 km/h; 75 mph). It is the third-highest classification used within the South-West Indian Ocean to classify tropical cyclones with.

Background

The South-West Indian Ocean tropical cyclone basin is located to the south of the Equator between Africa and 90°E.[1] The basin is officially monitored by Meteo France who run the Regional Specialised Meteorological Centre in La Reunion, while other meteorological services such as the Australian Bureau of Meteorology, Mauritus Meteorological Service as well as the United States Joint Typhoon Warning Center also monitor the basin.[1] Within the basin an intense tropical cyclone is a tropical cyclone that has 10-minute maximum sustained wind speeds between 65–89 knots (120–165 km/h; 75–100 mph).[1]
