Fujiwhara effect
Most of the storms originated from the Intertropical Convergence Zone. In late December into early January, tropical storms Bentha and Christelle persisted to the east of Madagascar, undergoing the Fujiwhara effect with each other. Later in January, Dorina became the second of three intense tropical cyclones, but weakened before passing near Rodrigues. Tropical Depression Eliceca and Tropical Storm Fodah both formed in the Mozambique Channel toward the end of January, bringing gusty winds and rainfall to the region. In February, Gail produced gusty winds on Rodrigues, and Tropical Storm Heida entered the basin from Australian region. Later in the month, Ingrid brought strong winds to Mauritius. Tropical storms Josta and Kylie developed toward the beginning of March from the same overall system, affecting Madagascar and Réunion, respectively. After they dissipated, Tropical Depression Lidy caused flooding and damage on Rodrigues due to heavy rainfall.
