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;

An area of low pressure developed close to Diego Garcia on November 14. It slowly organized as it made a northwest-south-southeast loop over the next two days. By the evening of November 16, the center of the storm became more well defined with convective rainbands wrapped tightly into it. Around that time, RSMC La Réunion started tracking the system as a tropical disturbance, and subsequently upgraded it to a Tropical Depression. Later that day, the JTWC issued a tropical cyclone formation alert on the system. The depression strengthened further and became the first named tropical storm of the year, on the same day. Mauritius Meteorological Service, which usually names storms in the region, named the system "Adjali". The JTWC also initiated advisories on Adjali. On November 17, MFR upgraded it to a Severe Tropical Storm. 
During November 25, RSMC La Reunion reported that Tropical Disturbance 2, had developed within a marginal environment for further development to the northeast of the Mascarene islands.
