[3] In addition to contributing towards the Island Climate Update outlook, the FMS and the BoM issued their own seasonal forecasts for the South Pacific region.
[2] They also reported that the tropical cyclone genesis trough was expected to be located, within the Coral Sea to the west of the International Date Line.
[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] They also predicted that Tonga, Papua New Guinea and Niue had an elevated chance of being impacted, while it was thought unlikely that French Polynesia, Kiribati and the Pitcairn Islands would be affected by a tropical cyclone.
[3] The FMS's outlook predicted that Fiji and Tonga had an elevated risk, while Tuvalu, French Polynesia and Kiribati, were thought to have a low to reduced chance of being affected by a tropical cyclone.
[2] The outlook also predicted that New Caledonia, Niue, Samoa, Solomon Islands, Tokelau, Vanuatu, Wallis & Futuna were thought to have a normal chance of being affected by a tropical cyclone.
This was attributed to a number of factors, including a poorly organised South Pacific convergence zone and a predicted La Niña episode not developing.
[citation needed] During February 5, the FMS reported that Tropical Disturbance 09F had developed within a trough of low pressure, about 210 km (130 mi) to the south-southwest of the Fiji's capital city: Suva.
The cyclone later reached its secondary peak intensity of 40 knots before it underwent extratropical transition, a process that completed during the early hours of February 23.
[10] Over the next couple of days, the system gradually developed further and became a tropical depression, as it moved south-eastwards within an area of low vertical wind shear.
[11] During February 21, the JTWC initiated advisories and designated it as Tropical Cyclone 07P, after an ASCAT satellite image had revealed the presence of 65–75 km/h (40–45 mph) winds, within its partially exposed circulation.
[12] The FMS subsequently named the system Bart as it had become a Category 1 tropical cyclone on the Australian scale, with peak 10-minute sustained wind speeds of 75 km/h (45 mph).
[13][14] After it had been named, Bart continued to move south-eastwards and passed to the west of the Southern Cook Islands, before it entered MetService's area of responsibility early on February 22.
[16] The system was poorly organised at this stage and lied within an upper-level monsoonal trough of low pressure in a moderate area of vertical wind shear.
[19] The FMS subsequently reported during April 9, that the system had become a Category 3 severe tropical cyclone, with peak 10-minute sustained winds of 155 km/h (95 mph).
[20] The JTWC subsequently reported that the cyclone had peaked with 1-minute sustained wind speeds of 165 km/h (105 mph), which made it equivalent to a Category 2 hurricane.
After reaching its initial peak as a Category 4 cyclone early on 6 May, the effects of wind shear and upwelling caused the storm to weaken.
[citation needed] During May 7, the FMS started to monitor Tropical Disturbance 22F that had developed within a trough of low pressure about 470 km (290 mi) to the northeast of Suva, Fiji.
[23] Just three hours later, the system intensified into a Category 1 tropical cyclone on the Australian scale, and was named Ella by the Fiji Meteorological Service (FMS).
[25] 01F was poorly organised and over the next day atmospheric convection surrounding the system significantly decreased as it moved south-eastwards, within an area of moderate to high vertical wind shear.
[28] During November 26, the third tropical disturbance of the season moved into the basin from the Australian region, while it was located about 820 km (510 mi) to the northwest of Nouméa, New Caledonia.
[29] Over the next couple of days, 03F moved eastwards towards Vanuatu and remained poorly organised, before the FMS issued its last advisory on the system during November 30.
[citation needed] Tropical Disturbance 18F developed along a pre-frontal trough of low pressure during March 18, about 455 km (285 mi) to the north of Suva, Fiji.
