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 Météo-France who run the Regional Specialised Meteorological Centre in La Réunion, while other meteorological services such as the Australian Bureau of Meteorology, Mauritius Meteorological Service as well as the United States Joint Typhoon Warning Center also monitor the basin.^[1] Within the basin a tropical cyclone is a tropical system that has 10-minute maximum sustained wind speeds between 65–89 knots (120–165 km/h; 75–100 mph).^[1]
