The South Pacific cyclone season is the period in a year when tropical cyclones usually form in the South Pacific basin Ocean, between 160°E and 120°W, which is the international area of responsibility for Fiji Meteorological Service`s RSMC Nadi tropical cyclone warning centre. Each section within the list notes how many tropical disturbances and tropical depressions (TD`s) developed during the season, while the number of tropical disturbances intensifying into tropical cyclones (TC`sJas) and ultimately Severe Tropical Cyclones (STC`s) are also noted. In this region a tropical disturbance is classified as a tropical cyclone, when it has 10-minute sustained wind speeds of more than 65 km/h (35 mph), that wrap halfway around the low level circulation centre, while a severe tropical cyclone is classified when the maximum 10-minute sustained wind speeds are greater than 120 km/h (75 mph).
