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;

In addition to the storms classified by the MFR, the JTWC tracked two storms in November. The first, classified as Tropical Cyclone 01S, formed on November 1, about halfway between Diego Garcia and Sumatra. It formed as a cyclone pair, along with a tropical storm in the northern Indian Ocean that struck India. The storm moved west-southwestward, passing near Diego Garcia on November 3. The JTWC assessed peak 1 minute winds of 105 km/h (65 mph) on November 7, although the storm subsequently weakened and dissipated on November 9. The other unofficial storm developed on November 24 near the eastern coast of Mozambique, classified as Tropical Cyclone 02S. Moving to the southwest, it quickly intensified to reach winds of 75 km/h (45 mph). Early on November 25, the storm moved ashore near Quirimbas National Park in the northeastern portion of Mozambique, and it dissipated a day later.
