The United States Joint Typhoon Warning Center (JTWC) and other national meteorological services including Météo-France and NOAA also monitored the basin during the season.

[3][5] In addition to contributing towards the Island Climate Update outlook, the FMS and the BoM both issued their own seasonal forecasts for the South Pacific region.

[2] This was based on the expected and predicted ENSO conditions, and the existence of the Pacific warm pool of sub-surface temperature anomalies in this region.

[3] The Island Climate Update Outlook predicted that Vanuatu and New Caledonia had a reduced chance of being affected by multiple tropical cyclones.

[3] The FMS outlook predicted that the Cook and Samoan Islands, Tokelau and Niue had a below average risk of being affected by a tropical cyclone.

[2] The Solomon Islands, Wallis and Futuna, Vanuatu and Tonga were predicted to face an average risk of being affected by a tropical cyclone.

[2] The FMS also predicted that there was an increased risk of severe tropical cyclones, affecting the region this year when compared to the previous season.

[6][7] Tropical Disturbance 01F developed on October 19, to the southeast of the Solomon Islands and moved westwards, as a small compact system before it was last noted during the next day.

[11] Over the next day the system moved westwards within an area of low vertical wind shear and rapidly consolidated further and became a tropical depression during October 20.

[9] However, this alert was cancelled during the next day after satellite imagery revealed a poorly defined low level circulation center, with unorganized atmospheric convection that had not consolidated and vertical wind shear over the system had started to increase.

[17] Over the next three days the system gradually developed further underneath an upper-level ridge of high pressure, within an area of moderate vertical wind shear, as it slowly moved towards the southwest.

[20][21] During January 13, the FMS reported that Tropical Disturbance 08F had developed, along a surface trough of low pressure to the southeast of the Solomon Island Makira.

Both RSMC Nadi and JTWC subsequently estimated that the system had reached its peak sustained winds of 90 km/h (55 mph), which made it a category 2 tropical cyclone on the Australian scale.

[46] The first numbered tropical disturbance of the year developed within an area of low vertical wind shear, to the southeast of the Solomon Islands on October 19.

[8][12][13] During the following day Tropical Disturbance 03F developed within an area of low shear, about 265 km (165 mi) to the northeast of Honiara on Guadalcanal in the Solomon Islands.

[48][49] On October 25, the FMS reported that Tropical Depression 04F had developed under an upper-level ridge of high pressure within an area of low windshear, about 330 km (205 mi) to the southeast of Honiara.

[50] Over the next couple of days the system affected the Solomon Islands, before it was last noted during October 27, as it was not expected to develop into a Category 1 tropical cyclone.

[59][60] On December 23, RSMC Nadi reported that Tropical Disturbance 06F had developed under an upper-level ridge of high pressure, within an area of moderate vertical wind shear to the northeast of the Santa Cruz Islands.

[57][62] Late on January 21, RSMC Nadi reported that Tropical Depression 09F had developed about 340 km (210 mi) to the southwest of the Cook Island: Palmerston.

[65][66][67] During January 22, RSMC Nadi also started monitoring Tropical Disturbance 10F, which had developed around 740 km (460 mi) to the northeast of Port Vila, Vanuatu.

[64] Over the next couple of days the system moved westwards into an area of low vertical windshear and the Australian region, where it developed into Tropical Cyclone Dylan during January 26.

[citation needed] During February 23, RSMC Nadi reported that Tropical Disturbance 14F had developed, within a trough of low pressure to the north-northwest of Maewo, Vanuatu.

The last tropical disturbance of the season: 21F, formed on March 17, about 500 km (310 mi) to the north of Rarotonga in the Cook Islands,[80] before dissipating two days later.
