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;
2015–16 South-West Indian Ocean cyclone season
Uriah entered the South-West Indian Ocean basin as a moderate tropical storm from the Australian region on February 14, where it was previously monitored by the Bureau of Meteorology's office in Perth. The storm tracked generally southwest, maintaining intensity. Early on February 16, Uriah began to intensify steadily, turning to the west as a subtropical ridge built in to the south of the system. Uriah also began to develop an eye, which became evident later that day. On February 17, Uriah attained hurricane-force (74 mph or 118 km/h) winds, becoming the first tropical cyclone of the season. Continuing to rapidly intensify, Uriah became an intense tropical cyclone twelve hours later. As the ridge previously located to the south of Uriah rebuilt to its east, the intense tropical cyclone began to turn to the south. As northwesterly wind shear began to affect the system, its appearance began to deteriorate and its convection lessened. Uriah rapidly weakened to a severe tropical storm by February 19, and it transitioned to a post-tropical depression shortly thereafter. Uriah's remnants meandered, nearly stationary in the southern Indian Ocean, until it became an extratropical depression and raced to the southeast.
