List of South Pacific tropical disturbances and tropical depressions

Tropical disturbances and tropical depressions are the two lowest classifications on the South Pacific version of the Australian scale. Over the years, 178 South Pacific tropical cyclones have failed to organize into Category 1 tropical cyclones, the most recent being Tropical Disturbance 08F (2020).

Background
The South Pacific tropical cyclone basin is located to the south of the Equator between 160°E and 120°W. The basin is officially monitored by the Fiji Meteorological Service and the New Zealand MetService, while other meteorological services such as the Australian Bureau of Meteorology, Météo-France as well as the United States Joint Typhoon Warning Center also monitor the basin. Within the region a tropical disturbance is classified as a non-frontal system that originates over the tropics and either has enhanced atmospheric convection or some indications of cyclonic wind circulation. A tropical disturbance is subsequently classified as a tropical depression or a tropical low, when there is a clearly defined circulation and the maximum 10-minute average wind speed is less than 34 kn near the centre.

Other systems
Tropical Cyclone Raquel (2014) developed into a Category 1 tropical cyclone, as it moved out of the region and into the Australian Region.

<!-- In addition to the 19 tropical cyclones listed above Severe Tropical Cyclone's: Harry, Rewa and Yasi, all became Category 5 Severe tropical cyclones within the South Pacific Ocean, after they had moved into the Australian region. Severe Tropical Cyclone Anne was estimated to have peaked by the JTWC, with one-minute sustained wind speeds of 260 km/h for six hours during January 11, 1988. This made it equivalent to a Category 5 tropical cyclone on the SSHWS, however, the FMS reported that the system had peaked with 10-minute sustained winds of 185 km/h, which made it a Category 4 severe tropical cyclone on the Australian scale. During 2017, a study into Category 4 and 5 tropical cyclones over the South Pacific during the 1980s, was published within the Royal Meteorological Society's International Journal of Climatology. This showed that the intensity of such tropical cyclones had been underestimated by the various warning centres during the decade. In particular, they estimated that Severe Tropical Cyclone's Oscar and Nisha-Orama had 1-minute sustained winds of 285 km/h, which would make them Category 5 tropical cyclones on the SSHWS.

Records and statistics
Within the official database for the region, as provided by the BoM, FMS and MetService, a total of XX tropical cyclones have been categorised as a Category 3 severe tropical cyclone. The earliest of these was Severe Tropical Cyclone Pam, which was estimated to have been a Category 5 severe tropical cyclone after a reanalysis of the data was performed by the BoM. The strongest and most intense of these was Severe Tropical Cyclone Winston of the 2015-16 season, which was estimated to have 10-minute sustained wind speeds of 280 km/h and a minimum pressure of 884 hPa at its peak intensity. Severe Tropical Cyclone Susan maintained its Category 5 status for around 72 hours and was the system that maintained its Category 5 status the longest. -->
