1982–83 South-West Indian Ocean cyclone season
The 1982–83 South-West Indian Ocean cyclone season was least active cyclone season in the basin since 1961–1962. There were six systems that were named, although three of them – Arilisy, Clera, and Fely – failed to intensify beyond tropical depression status. No storms reached tropical cyclone status, according to the official warning agency for the basin, Météo-France, although the two strongest storms – Bemany and Elinah – peaked just below that intensity. The first named storm, Arilisy, formed on October 27, and dissipated without having affected land. However, the Joint Typhoon Warning Center (JTWC), which is an unofficial warning center for the basin, briefly tracked a tropical depression in July. The next storm was Bemany, which passed east of Mauritius near peak intensity in early December. Tropical Depression Clera existed briefly in the middle of September, and Tropical Storm Dadafy moved across the eastern portion of the basin in late December.
The only deadly storm of the season was Elinah, which formed on January 9 in the Mozambique Channel. It moved to the southwest and was intensifying when it struck Comoros on January 11. There, high winds and waves heavily damaged banana and coconut crops, and the storm damaged or destroyed 4,357 buildings. High waves knocked 40 people off a pier on Anjouan, killing 33 of them. Damage in Comoros totaled $23.1 million (1983 USD). Elinah intensified before brushing the coast of Mozambique, and it dissipated on January 9. Aside from a weak storm classified by the JTWC in February, there was minimal activity for several months. The final storm of the season was Tropical Depression Fely, which dropped moderate rainfall in eastern Madagascar in late June.
==Season summary==
The season was the least active since the 1961–1962 season.〔 It occurred during a significant El Niño event. Its inactivity was comparable to the 2010–11 season which had three named storms. There were 13 days when storms were active, the same as 2010–11, although the latter season also had a long-lasting subtropical cyclone. It is estimated that Tropical Depression Fely and two of the other storms in this season would not have been named during the 2010–11 season.
There were six storms named by the weather service in Madagascar or Mauritius, with advisories issued by Météo-France's meteorological office at Réunion (MFR). At the time, the MFR area of warning responsibility was from the coast of Africa to 80° E, and the agency primarily used the Dvorak technique to estimate the intensities of tropical cyclones. The Joint Typhoon Warning Center (JTWC), which is a joint United States Navy – United States Air Force task force that issues tropical cyclone warnings for the region, also tracked a short-lived tropical storm in February, which formed on February 5 northeast of Mauritius. The system tracked to the southeast, reaching peak winds of 65 km/h (40 mph) before dissipating on February 8 northwest of Rodrigues.
