Conclusion
On March 10, Météo-France noted an area of convection around 60°E, and numbered it 12R. The next day, M-F upgraded it to a tropical disturbance as the Joint Typhoon Warning Center issued a Tropical Cyclone Formation Alert on it. The disturbance continued to strengthen, and later that day M-F upgraded 12R to a tropical depression. Under favorable conditions, it strengthened into a moderate tropical storm early on March 12. Originally, the storm was referred to as "Indlada" by M-F, but this was later corrected to the correct name, Indlala, which was contributed by Swaziland. Indlala continued to strengthen, and it was upgraded to a severe tropical storm. It reached tropical cyclone intensity on March 13 in favourable conditions, with infrared satellite imagery showing an intermittent eye. It continued to strengthen in a favourable environment, with a well-defined eye, and reached intense tropical cyclone strength the next day as it tracked westward towards Madagascar. It made landfall early on March 15 as it was undergoing an eyewall replacement cycle, near Antalaha, Madagascar, and weakened quickly while over land. It dissipated over land on March 17, and the final warning was issued.
Indlala killed 150 people and left another 126 missing. A total of 188,331 people were also left homeless due to the storm. Damages from Indlala amounted to $240 million.
