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;
Cyclone Bijli
Cyclone Bijli (JTWC designation: 01B, also known as Cyclonic Storm Bijli), was the first tropical cyclone to form during the 2009 North Indian Ocean cyclone season. Bijli formed from an area of Low Pressure on April 14. Later that evening, RSMC New Delhi upgraded the low pressure area to a Depression and designated it as BOB 01. The Joint Typhoon Warning Center (JTWC) then issued a Tropical Cyclone Formation Alert for the system and soon after designated it as Tropical Depression 01B. On the evening of April 15, both RSMC New Delhi and the JTWC reported that the system had intensified into a tropical storm, with the former naming it Bilji. Soon after, Bilji reached its peak intensity as it approached the coast of Bangladesh. However, on the morning of April 17, Bijli weakened to a deep depression due to land interaction, before making landfall just south of Chittagong. The remnants of Bilji continued to weaken as they tracked across northern Myanmar, before RSMC New Delhi issued their last advisory on April 18. The word Bijli refers to lightning in Hindi.
