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;
2000 North Indian Ocean cyclone season
Similar to the previous storm, the active monsoon trough spawned a low pressure area over the Andaman Sea on October 24. There was a weak center that had good outflow. On October 25, the IMD classified the system as a depression about 925 km (575 mi) southeast of Kolkata. The system moved to the northwest and developed more convection close to the center, although the thunderstorms were intermittent. Turning more to the north, the depression intensified into a deep depression and later cyclonic storm on October 27, reaching peak winds of 65 km/h (40 mph); the JTWC also classified it as Tropical Cyclone 02B. That day, the wind shear increased, although the convection was able to increase over the center and organize into a comma-shaped rainband. Early on October 28, the storm made landfall in southern Bangladesh near Mongla, by which time the wind shear had displaced much of the convection to the northeast. It rapidly weakened over land, degenerating into a remnant low over northern Bangladesh early on October 29.
