Cyclone Kamisy
Intense Tropical Cyclone Kamisy was considered the worst tropical cyclone to affect northern Madagascar since 1911. A tropical disturbance formed near Diego Garcia on April 3, 1984 and subsequently moved westward, intensifying into a moderate tropical storm two days later. Given the name Kamisy, the storm gradually intensified into an intense tropical cyclone by April 9. Kamisy reached winds of 170 km/h (105 mph) before making landfall in extreme northern Madagascar near Diego Suarez. It weakened upon entering the Mozambique Channel, but briefly re-intensified on April 10. That day while passing near Mayotte, the cyclone turned  to the southeast, striking Madagascar again near Majunga. Kamisy quickly crossed the country. After emerging into the Indian Ocean off the east coast of Madagascar, the system reintensified into a moderate tropical storm before dissipating on April 16. In northern Madagascar, Kamisy produced wind gusts of , which destroyed 80% of the city of Diego Suarez. About 39,000 people were left homeless in the area, and there were five deaths. In western Madagascar, the cyclone dropped of rainfall in 24 hours in Majunga, which damaged rice fields in the region after causing widespread river flooding. Additionally, the storm destroyed about 80 % of Majunga. Throughout the country, Kamisy caused $250 million in damage and 68 deaths, with 215 people injured and 100,000 left homeless. Fifteen people were killed and 30 others were injured in Mahajanga. Following the storm, emergency food and medical supplies were rushed into the nation. In addition to the impact to Madagascar, one death and severe damage was reported in the Comoros Islands, where all of the banana crop was destroyed. Meteorological history. Cyclone Kamisy originated from an area of convection that formed in early April. On April 3, the system was assigned a Dvorak rating of T2.0  and was respectively upgraded into a moderate tropical storm by the Météo-France office on Reunion (MFR). However, the storm was not classified by the Joint Typhoon Warning Center (JTWC) until that evening. The storm initially tracked west-southwest, but after briefly weakening into a tropical depression, Kamisy began to turn west. On April 5, the storm was upgraded into a moderate tropical storm for the second time; the JTWC followed suit and upgraded Kamisy into a tropical storm several hours later while located about west of Diego Garcia. Kamisy steadily intensified and on April 6, the JTWC reported that  it attained hurricane-force winds despite MFR estimating winds of . Early on April 7, however, Kamisy was upgraded into a severe tropical storm as it had earned a rating of T4.0 on the Dvorak scale. Thereafter, the storm began to undergo rapid deepening. Later that day, the JTWC announced that Kamisy attained winds of , equivalent to a mid-level Category 2 hurricane on the Saffir-Simpson Hurricane Wind Scale. Meanwhile, MFR upgraded the system into cyclone intensity. After briefly leveling off in intensity, the storm attained peak intensity of later that day. Early on April 8, the JTWC estimated that  it reached its peak intensity of . Around this time, Kamisy was assigned a T6.0 rating via the Dvorak technique. After maintaining peak intensity for less than a day, it weakened slightly. On April 9, the storm brushed the northern Madagascar coast as a severe tropical storm, though the JTWC suggested that Kamsiy was considerably stronger. However, the afternoon to storm emerged into the extreme northern Mozambique Channel, where it passed near Mayotte, with little change in strength. After sharply turning south-southwest, Kamisy briefly regained tropical cyclone intensity, but resumed weakening as it approached the coast. While still a moderate  tropical storm, it made landfall along the north-central part of the nation on April 12, near Tamative. At the time of landfall, the JTWC noted that Kamisy was a minimal hurricane. The storm quickly weakened overland and was a tropical depression by the time it had emerged into the Indian Ocean. Shortly thereafter, the storm restrengthened into a moderate tropical storm, but this trend was short-lived. The JTWC downgraded Kamisy into a tropical depression at 0600 UTC on April 14. The agency issued the last warning on the system the following day, even though MFR kept tracking the  system until the morning hours of April 16. At this time, Kamisy was located about southwest of the southern tip of Madagascar. Impact. Madagascar. Throughout Madagascar, a total of 68 casualties were reported and 100,000 people were left homeless. Damage totaled to more than $250 million (1984 USD).

Aftermath. Following the storm, emergency food and medical supplies were rushed into the nation. Due to Madagascar's small budget, it did not have the resources to repair all the  damage alone. Two French rescue mission, including one from Reunion, provided victims with food and medical assistance to Madagascar and Mayotte. Furthermore, the Malagasy Red Cross launched an appeal for blankets, clothes, tents, and medicine. The United States provided $25,000 in cash and $15,000 worth of other items.

A private consulting company was later hired to conduct a post-storm assessment; a training program was subsequently launched, which had a budget of $3.5 million. The training program lasted until the 1985–86 South-West Indian Ocean cyclone season, when Cyclone Honorinina devastated the  nation. Sailors from the US Navy's warship USS Hector, were diverted to assist in the relief effort in Diego-Suarez, between April 23 and May 1, 1984. The warship was the first American naval vessel to visit the port after Madagascar's Government banned the superpowers including France and the United States from using it during the 1970s and were awarded two Humanitarian Service Medals.
