Draft:Tropical cyclones in 1990

During 1990, tropical cyclones formed within seven different tropical cyclone basins, located within various parts of the Atlantic, Pacific and Indian Oceans. During the year, a total of 124 systems formed with 92 of these developing further and were named by the responsible warning center. The strongest tropical cyclone of the year was Typhoon Flo. The deadliest tropical cyclone was the 1990 Andhra Pradesh cyclone, while the costliest was also Typhoon Flo. Four Category 5 tropical cyclones formed in 1990, which all formed in the Western Pacific.

Tropical cyclone activity in each basin is under the authority of an RSMC. The National Hurricane Center (NHC) is responsible for tropical cyclones in the North Atlantic and East Pacific. The Central Pacific Hurricane Center (CPHC) is responsible for tropical cyclones in the Central Pacific. Both the NHC and CPHC are subdivisions of the National Weather Service. Activity in the West Pacific is monitored by the Japan Meteorological Agency (JMA). Systems in the North Indian Ocean are monitored by the India Meteorological Department (IMD). The Météo-France located in Réunion (MFR) monitors tropical activity in the South-West Indian Ocean. The Australian region is monitored by five TCWCs that are under the coordination of the Australian Bureau of Meteorology (BOM). Similarly, the South Pacific is monitored by both the Fiji Meteorological Service (FMS) and the Meteorological Service of New Zealand Limited. Other, unofficial agencies that provide additional guidance in tropical cyclone monitoring include the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) and the Joint Typhoon Warning Center (JTWC).

3 The wind speeds for this tropical cyclone basin are based on the IMD scale which uses 3-minute sustained winds.

4 The wind speeds for the Atlantic, Eastern and Central Pacific tropical cyclone basin are based on the Saffir–Simpson scale which uses 1-minute sustained winds.

5 The wind speeds for this tropical cyclone are based on Météo-France which uses gust winds.
