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

[3] They also reported that the tropical cyclone genesis trough was expected to be displaced far eastwards of its long term average position.

[3] 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][4] With the exception of Kiribati, Papua New Guinea, New Caledonia, Niue, and Tonga, the Island Climate Update predicted that all areas would experience an elevated risk of being affected by multiple tropical cyclones.

[4] The FMS's outlook predicted that the Solomon and Northern Cook Islands, Wallis and Futuna, Tokelau, Samoa, and French Polynesia had a highly elevated chance of being affected by a tropical cyclone.

Later that month RSMC Nadi started to monitor Tropical Disturbance 01F, which had developed to the north-northeast of Honiara in the Solomon Islands.

Over the next few days the system slowly organised further, before it was classified as Tropical Cyclone 01P by the Joint Typhoon Warning Center, on August 2.

Ula subsequently weakened, but later rapidly re-intensified into a Category 4 severe tropical cyclone, reaching its peak intensity.

[9][10] The system lay to the north of an upper level subtropical ridge of high pressure in an area of moderate vertical wind shear.

[9] Over the next couple of days the system slowly organised further as it steered south-eastwards into an area of decreasing vertical wind shear.

[citation needed] During October 12, Tropical Disturbance 02F developed along the South Pacific convergence zone, while it was located about 450 km (280 mi) to the northwest of Rotuma.

[12][13] The system was located within a favourable environment for further development, with low to moderate vertical wind shear, and it lay under an upper-level ridge of high pressure.

[citation needed] On November 23, Tropical Disturbance 03F developed within a trough of low pressure, about 500 km (310 mi) to the northeast of Suva, Fiji.

[15] The system lay in an area of low to moderate vertical wind shear, to the south of an upper-level ridge of high pressure.

Over the next few days the system moved eastwards and gradually developed further, becoming a tropical depression during December 29, while it was located to the north of the Samoan Islands.

[19] On January 10, the FMS reported that Tropical Disturbance 08F had developed about 100 km (60 mi) to the northwest of Penrhyn in the Northern Cook Islands.

[22] On January 14, the JTWC issued a TCFA alert as 08F was located in moderate wind shear and warm sea-surface temperatures, which were conductive for tropical development.

[33][34] It reached its record intensity the next day with ten-minute sustained winds of 280 km/h (175 mph) and a pressure of 884 hPa (mbar; 26.10 inHg), shortly before making landfall on Viti Levu, Fiji.

[39] In advance of the storm's arrival in Fiji, numerous shelters were opened,[40] and a nationwide curfew was instituted during the evening of February 20.

[41] Striking Fiji at Category 5 intensity on February 20, Winston inflicted extensive damage on many islands and killed at least 44 people.

[48] The system subsequently moved southwards and rapidly weakened during the next day, crossing back into BoM's area of responsibility.

[48] During February 23, Tropical Disturbance 11F developed underneath an upper-level ridge of high pressure, about 850 km (530 mi) to the northwest of Tahiti, French Polynesia.

The system was subsequently named Amos during April 20, after it had developed into a tropical cyclone and started to move north-westwards towards the island nation of Tuvalu.

[53] The system subsequently moved westwards and out of the basin during July 4, as it impacted the Solomon Islands, with high wind gusts and heavy rain.

[54] Over the next day the poorly organised system moved westwards, underneath an upper-level ridge of high pressure before it dissipated during December 2.

[55][56] During December 27, Tropical Disturbance 06F developed to the north of Wallis Island, in an area of moderate to high vertical wind shear.

[58] However, during that day as the system moved southwards in an area of low vertical wind shear, atmospheric convection decreased in magnitude before it was last noted during March 1.

[69] During April 20, Tropical Disturbance 18F developed within an area of low to moderate vertical wind-shear, to the south of an upper-level ridge of high pressure to the north of the Southern Cook Islands.
