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;
1989–90 South-West Indian Ocean cyclone season
On January 31, a tropical disturbance formed just east of Agaléga. Moving southeastward, it intensified into Moderate Tropical Storm Cezera on February 1, the same day that the JTWC began tracking it as Tropical Cyclone 14S. Cezera quickly intensified, and the JTWC upgraded it to the equivalence of a minimal hurricane on February 3 with 1‑minute peak winds of . By contrast, the MFR only estimated peak 10‑minute winds of . By February 4, Cezera began a Fujiwhara interaction with Tropical Cyclone Dety, which was located to the east; this caused the former storm to turn back to the northwest while gradually weakening. On February 6, the storm turned to the south and later southeast, weakening to tropical depression status that day. Cezera briefly re-intensified into a moderate tropical storm on February 7, but weakened again on the next day while passing just north of St. Brandon. After turning more to the east-northeast, the system turned sharply southward on February 10, and dissipated the next day.
