caption_attribution_description: English: This map shows the tracks of all tropical cyclones in the 1991-92 South-West Indian Ocean cyclone season. The points show the location of each storm at 6-hour intervals. The colour represents the storm's maximum sustained wind speeds as classified in the Saffir-Simpson Hurricane Scale (see below), and the shape of the data points represent the nature of the storm.

context_page_description: The 1991–92 South-West Indian Ocean cyclone season was an average cyclone season in which most storms remained over open waters. At the time, the season lasted from November 15, 1991, to April 30, 1992, although this season began early when three tropical depressions formed before the official start. The second, designated Tropical Depression A2 by the Météo-France office on Réunion, passed north of Madagascar on October 16 before weakening. The first named storm was Severe Tropical Storm Alexandra, which developed on December 18 from the monsoon trough; many other storms during the year originated in this manner. Tropical Storm Bryna was the only tropical storm of the season to make landfall, having struck northeastern Madagascar on January 2. The basin was most active in February, when five named storms developed, including Tropical Depression Elizabetha which struck western Madagascar. In early March, Cyclone Harriet entered the basin from the Australian region and was renamed Heather. It intensified to peak winds of 165 km/h, making Heather the strongest storm of the season.
