The 2016–17 South Pacific cyclone season is the period of the year when most tropical cyclones form within the South Pacific Ocean to the east of 160°E. The season officially runs from November 1, 2016 to April 30, 2017, however a tropical cyclone could form at any time between July 1, 2016 and June 30, 2017 and would count towards the season total. During the season, tropical cyclones will be officially monitored by the Regional Specialized Meteorological Center (RSMC) in Nadi, Fiji and the Tropical Cyclone Warning Centers in Brisbane, Australia and Wellington, New Zealand. The United States Armed Forces through the Joint Typhoon Warning Center (JTWC) will also monitor the basin and issue unofficial warnings for American interests. RSMC Nadi attaches a number and an F suffix to tropical disturbances that form in or move into the basin while the JTWC designates significant tropical cyclones with a number and a P suffix. RSMC Nadi, TCWC Wellington and TCWC Brisbane all use the Australian Tropical Cyclone Intensity Scale and estimate windspeeds over a period of ten minutes, while the JTWC estimated sustained winds over a 1-minute period, which are subsequently compared to the Saffir–Simpson hurricane wind scale (SSHWS).

Tropical Disturbance 01F

Duration | November 12 – November 13 | ||
Peak intensity | Winds not specified 1008 hPa (mbar) |
During November 12, the first tropical disturbance of the season, developed to the north-northeast of the island nation: Niue.[4] Over the next day atmospheric convection surrounding the system significantly decreased, as the system moved south-eastwards within an area of moderate to high vertical wind shear.[5] The system was subsequently last noted during November 13, as it was not expected to develop into a tropical cyclone.[5]
Tropical Disturbance 02F

On November 23, RSMC Nadi noted a tropical disturbance that formed in the eastern South Pacific.
Tropical Disturbance 03F

Duration | November 29 – November 30 | ||
Peak intensity | Winds not specified 1000 hPa (mbar) |
During November 29, Tropical Disturbance 03F moved into the basin from the Australian region, about 820 km (510 mi) to the northwest of Noumea, New Caledonia.[6] Over the next day the system moved eastwards and remained poorly organised until it was last noted during November 30, while it was located about 365 km (225 mi) to the north of Noumea.
Storm names
Within the Southern Pacific a tropical depression is judged to have reached tropical cyclone intensity should it reach winds of 65 km/h, (40 mph) and it is evident that gales are occurring at least halfway around the center. With tropical depressions intensifying into a tropical cyclone between the Equator and 25°S and between 160°E - 120°W named by the RSMC Nadi. However should a tropical depression intensify to the south of 25°S between 160°E and 120°W it will be named in conjunction with RSMC Nadi by TCWC Wellington. Should a tropical cyclone move out of the basin and into the Australian region it will retain its original name. The next 10 names on the naming list are listed here below.[7]

Season effects
This table lists all the storms that developed in the South Pacific to the east of longitude 160°E during the 2016–17 season. It includes their intensity on the Australian tropical cyclone intensity scale, duration, name, landfalls, deaths, and damages. All data is taken from RSMC Nadi and/or TCWC Wellington, and all of the damage figures are in 2016 USD.
