Tropical Cyclone Manou was a relatively rare May tropical cyclone that affected southeastern Madagascar. The final named storm of the 2002–03 South-West Indian Ocean cyclone season, Manou formed on May 2 to the southwest of Diego Garcia. It moved generally to the southwest for much of its duration, steered by a ridge to the southeast. Manou affected Saint Brandon and Mauritius with gusty winds. After an initial strengthening phase, the storm weakened but later re-intensified as it approached Madagascar. Manou developed a well-defined eye and reached peak winds only 19 km (12 mi) from the eastern Madagascar coastline. For about 12 hours, the cyclone stalled before turning to the south and weakening. Manou became extratropical on May 10 and dissipated three days later.
