Dvorak technique
In general, sea surface temperatures were warmest near the equator in the northeast portion of the basin, and in the Mozambique Channel between Mozambique and Madagascar. During the season, the Météo-France office (MFR) on Réunion island issued warnings in tropical cyclones within the basin. The agency estimated intensity through the Dvorak technique, and warned on tropical cyclones in the region from the coast of Africa to 80° E, south of the equator. The Joint Typhoon Warning Center (JTWC), which is a joint United States Navy – United States Air Force task force, also issued tropical cyclone warnings for the southwestern Indian Ocean.
