1999–2000 South-West Indian Ocean cyclone season
The 1999–2000 South-West Indian Ocean tropical cyclone season was the first on record in which two storms – Leon–Eline and Hudah – struck Mozambique at tropical cyclone intensity, or with maximum sustained winds of at least 120 km/h (75 mph). The most notable storm of the season was Eline, which was the longest-lasting storm on record in the basin. It lasted for 29 days while traversing the southern Indian Ocean, making the strongest landfall in decades along eastern Madagascar in late February. The storm was the first in a series of three storms that struck the country in early 2000, along with Gloria in March and Hudah in April. Collectively, the three storms killed at least 316 people. The season started on November 1, 1999, and ended for most of the basin on April 30, 2000; for Mauritius and the Seychelles, the season continued until May 15. These dates conventionally delimit the period of each year when most tropical cyclones form in the basin;

While at peak intensity, Jery began turning to the south, due to reaching the western edge of a ridge. An approaching trough increased wind shear over the storm, causing the convection to diminish and expose the center. Late on April 10 it weakened below tropical cyclone status, and the next day Jery became extratropical. Shortly thereafter the remnants crossed into the Australian region, dissipating on April 13.
Cyclone Kesiny was the final named storm of the season, forming near the equator on May 2, within a trough enhanced by a pulse of the Madden–Julian oscillation that sparked three other storms. Kesiny initially moved to the southeast, but later turned to the southwest due to a strengthening ridge. On May 6, it intensified into a tropical cyclone, but later weakened and was not expected to re-strengthen. However, Kesiny developed an eye and re-intensified into a tropical cyclone on May 9, reaching peak winds of before striking Madagascar about southeast of Antsiranana. This made it the first recorded tropical cyclone to make landfall in the month of May in the basin. It weakened while crossing the country, and after turning to the south it struck the country again before dissipating on May 11.
