[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][3] The Island Climate Update Outlook predicted that New Caledonia, Tonga, New Zealand and Papua New Guinea had an above average chance of being impacted by a tropical cyclone or their remnants.
[3] The FMS's outlook predicted that Vanuatu, New Caledonia, Fiji as well as Wallis and Futuna had a normal chance of being impacted by a tropical cyclone.
[5] On 3 February, the Fiji Meteorological Service (FMS) started to monitor Tropical Disturbance 07F, which had developed within a trough of low pressure, about 435 km (270 mi) to the southeast of Honiara in the Solomon Islands.
[6][7] Over the next couple of days, the system moved erratically near northern Vanuatu and remained poorly organized, with convection located to the south of the low-level circulation center.
[10][11] On 9 February, the United States Joint Typhoon Warning Center (JTWC) initiated advisories on the system and designated it as Tropical Cyclone 09P, after an ASCAT image showed that it had winds of 65–75 km/h (40–45 mph) in its northern semicircle.
[14] On 10 February, Gita rapidly intensified to a category 3 severe tropical cyclone on the Australian scale[15] while traversing anomalously warm sea surface temperatures of between 28–29 °C (82–84 °F).
[20][21] At this time the disturbance had a broad low-level circulation and was located within a very favourable environment for further development, with low vertical wind shear and warm sea surface temperatures.
[27] After it was named, Hola started developing a weak low level eye feature, before it was classified as a category 2 tropical cyclone as it passed in between the islands of Pentecost and Ambrym.
[28][29] The system subsequently passed over the island of Malekula and moved into the Coral Sea during March 7, where it rapidly consolidated and developed a 10 km (5 mi) pinhole eye.
On March 11, the FMS reported that Tropical Disturbance 10F, had developed about 85 km (55 mi) to the southwest of Rennell and Bellona Province of the Solomon Islands.
[citation needed] During March 20, the FMS reported that Tropical Disturbance 11F had developed within an area of low to moderate vertical wind shear, over the eastern Solomon Islands around 200 km (125 mi) to the east of Honiara.
[36] Over the next few days, the system remained weak as it moved erratically around the Solomon Islands and was classified as a tropical depression during March 22.
[citation needed] During March 29, the Fiji Meteorological Service reported that Tropical Disturbance 12F had developed about 350 km (215 mi) to the east of Port Vila in Vanuatu.
[39] However, the disturbance was located to the south of a ridge of high pressure, and within a favourable environment for further development, with low to moderate levels of vertical wind shear and warm sea surface temperatures of around 28–30 °C (82–86 °F).
[42] Despite not making landfall, Cyclone Josie caused heavy rainfall and sustained gale-force winds in southern Fiji.
[44] Tropical Cyclone Keni impacted Fiji and caused the cast and crew of the 37th season of the American reality competition series, Survivor, to be temporarily evacuated to the production's base camp.
[49][50] Over the next couple of days, the disturbances moved southeastwards into areas of high vertical wind shear, before they were last noted during December 18 and 19 as they dissipated to the southeast of Samoa.
[53] The system had a well defined low-level circulation, and was located within an area of warm sea surface temperatures and marginal vertical wind shear.
[55] On May 4, 2018, a system identified as a subtropical cyclone formed east of 120°W, near 80°W, just a few hundred miles off the coast of Chile, with researchers unofficially naming the storm Lexi.
[57] On May 9, the satellite services division of the NOAA classified the system as a weak subtropical storm, despite occurring in cooler (below 20 °C) sea surface temperatures.
