1983–84 South-West Indian Ocean Cyclone Season
The 1983–84 South-West Indian Ocean cyclone season featured above normal activity and several deadly storms. There was steady storm activity from December through April due to favorable conditions, such as warm sea surface temperatures and an active monsoon. The first named storm – Andry – was tied for the strongest with Bakoly, Jaminy, and Kamisy. Cyclone Andry passed near Agaléga island within Mauritius, damaging or destroying every building there and killing one person. It later struck Madagascar, the first of three storms to strike the nation within two months, which collectively caused $25 million in damage and 42 deaths. The third of these storms, Tropical Storm Domoina, caused deadly flooding in southeastern Africa that killed 242 people and caused $199 million in damage. The storm destroyed more than 50 small dams in Madagascar and caused the worst flooding in Swaziland in 20 years. In addition three of the first storms affecting Madagas ...

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 ...

Mahajanga
Mahajanga (French: Majunga) is a city and an administrative district on the northwest coast of Madagascar. The city of Mahajanga (Mahajanga I) is the capital of the Boeny Region. The district (identical to the city) had a population of 220,629 in 2013. Mahajanga is a tourist destination for Malagasy tourists and international travelers, with beaches, a coconut-lined boardwalk ("Le Bord", short for "Bord de la mer" or sea-side), and eight months of hot, virtually rain-free weather. City Mahajanga is a seaport, the second most important one in Madagascar after Toamasina. The marine terminal accommodates containerships and small (150 gross ton) general cargo freighters. Because of limited water depth at the wharf, only small ships can call at the terminal. Deeper-draft ships anchor off the terminal and transfer cargoes to and from barges, which move it to and from the terminal. Severe storms during December 2006 damaged the bulkhead, allowing water to flow in and wash backfi ...

It had an estimated population of 115,015 in 2013. History The bay and city originally used the name ''Diego-Suárez'', named after Diogo Soares, a Portuguese navigator who visited the bay in 1543–44.

Tropical Cyclone Scales
Tropical cyclones are ranked on one of five tropical cyclone intensity scales, according to their maximum sustained winds and which tropical cyclone basins they are located in. Only a few scales of classifications are used officially by the meteorological agencies monitoring the tropical cyclones, but other scales also exist, such as accumulated cyclone energy, the Power Dissipation Index, the Integrated Kinetic Energy Index, and the Hurricane Severity Index. Tropical cyclones that develop in the Northern Hemisphere are unofficially classified by the warning centres on one of three intensity scales. Tropical cyclones or subtropical cyclones that exist within the North Atlantic Ocean or the North-eastern Pacific Ocean are classified as either tropical depressions or tropical storms. Should a system intensify further and become a hurricane, then it will be classified on the Saffir–Simpson hurricane wind scale, and is based on the estimated maximum sustained winds over a 1-minut ...

Malagasy Franc
The franc (ISO 4217 code ''MGF'') was the currency of Madagascar until January 1, 2005. It was subdivided into 100 centimes. In Malagasy the corresponding term for the franc is ''iraimbilanja'', and five Malagasy francs is called ''ariary''. History The first francs to circulate in Madagascar were French francs. These were supplemented during the First World War by emergency issues, including issues of postage stamps fixed to pieces of card in denominations of 0.05 up to 2 francs. The Banque de Madagascar was created on July 1, 1925, by the French government. The currency was issued by the government-owned ''Banque de Madagascar'' and was pegged at par to the French franc. Only banknotes were issued with French coins continuing to circulate. When the Comoro Islands became a separate French territory, the name of the issuing bank was changed to Banque de Madagascar et des Comores. The Madagascar-Comores CFA franc (XMCF) replaced the franc of Madagascar on December 26, 1945, with ...

Diego Garcia
Diego Garcia is an island of the British Indian Ocean Territory, a disputed overseas territory of the United Kingdom. It is a militarised atoll just south of the equator in the central Indian Ocean, and the largest of the 60 small islands of the Chagos Archipelago. The Portuguese were the first Europeans to find it and it was then settled by the French in the 1790s and transferred to British rule after the Napoleonic Wars. It was one of the "Dependencies" of the British Colony of Mauritius until the Chagos Islands were detached for inclusion in the newly created British Indian Ocean Territory (BIOT) in 1965. In 1966, the population of the island was 924. These people were employed as contract farm workers primarily on copra plantations owned by the Chagos-Agalega company. Although it was common for local plantation managers to allow pensioners and the disabled to remain in the islands and continue to receive housing and rations in exchange for light work, children after the ...

Joint Typhoon Warning Center
The Joint typhoon Warning Center (JTWC) is a joint United States Navy – United States Air Force command in Pearl Harbor, Hawaii. The JTWC is responsible for the issuing of tropical cyclone warnings in the North-West Pacific Ocean, South Pacific Ocean, and Indian Ocean for all branches of the U.S. Department of Defense and other U.S. government agencies.
