2012–13 South Pacific cyclone season

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.

[4] They noted that the current neutral ENSO conditions would historically suggest the South Pacific region as a whole would experience near average tropical cyclone activity during the coming season.

[3] RSMC Nadi's outlook predicted that New Caledonia, Southern Tonga, Tokelau, Tuvalu, Solomon Islands, Fiji and Vanuatu had an average risk of being affected by a tropical cyclone.

[2] Wallis and Futuna, Samoa, Northern Tonga, Niue, Cook Islands and French Polynesia were predicted to face an above average chance of being affected by a tropical cyclone.

[2] RSMC Nadi also predicted that there was a potential risk in the chances of severe tropical cyclones, affecting the region this year when compared to the previous season.

[9][10] Over the next few days the system moved slowly and gradually developed further in an area of low vertical wind shear and was declared a tropical depression during November 20.

[9][11] The system subsequently turned towards the south-southeast and impacted Vanuatu, before it moved into an area of unfavourable conditions for further development, including high vertical wind shear and lower sea surface temperatures during November 22.

[19] During December 9, RSMC Nadi reported that Tropical Depression 03F had developed in an area of high vertical windshear, about 600 km (375 mi) to the northeast of Avarua on the Cook Island of Rarotonga.

On December 9, RSMC Nadi started to monitor a weak tropical depression, that had developed within the South Pacific convergence zone, about 700 km (435 mi) to the northeast of Suva, Fiji.

[20][21] Over the next two days, the depression gradually developed further in an area of low vertical windshear and favourable sea surface temperatures, as it was steered eastwards by an upper level ridge of high pressure.

The US Ambassador to New Zealand and Samoa David Huebner confirmed the United States had provided NZ$ 60,000 to the Samoan Red Cross for relief operations.

As the legislators prepared to receive initial assessments of the economic damage wrecked by Evan, the bill was expected to be at least NZ$ 200,000,000, and possibly rise as high as 300 million.

[28][29][30][31][32] On December 26, RSMC Nadi reported that Tropical Disturbance 05F had developed within an area of low to moderate vertical windshear about 1075 km (670 mi) to the north of Port Vila, Vanuatu.

[35] During December 27, the depression started to move towards the southwest and the southern Solomon Islands, as convection surrounding the centre and the general organization of the system continued to increase.

[37][38] Later that day RSMC Nadi reported that the depression had become a category one tropical cyclone and named it Freda, as it continued to move towards the southwest and passed over Rennell Island.

[40][41] During that day the system developed an 20 km (10 mi) wide eye while significantly intensifying further, with RSMC Nadi reporting by 1800 UTC that Freda had become a category 3 severe tropical cyclone with 10-minute sustained windspeeds of 150 km/h (95 mph).

[48] During the next day the JTWC issued their final advisory on the system after the low level circulation center had become fully exposed before the remnant tropical depression crossed the northern part of New Caledonia's Grande Terre Island.

[60] On January 26, RSMC Nadi reported that Tropical Depression 11F had developed within an area of high vertical windshear about 614 km (380 mi) to the southeast of Suva, Fiji.

[61][62] On February 7, RSMC Nadi reported that Tropical Disturbance 14F had developed under an upper level ridge of high pressure in an area of low vertical windshear, about 450 km (280 mi) to the east of the Cook Island: Suwarrow.

[65] By February 11, Haley weakened into a tropical depression, with the low level circulation center becoming fully exposed, with most of the convection displaced to the far east due to wind shear from the west, overall decreasing its organization.

[66] On February 28, RSMC Nadi started to monitor a tropical disturbance that had developed, about 390 km (240 mi) to the south of Honiara on the Solomon Island of Guadalcanal.

[73] The remnants of Sandra bought areas of heavy rain and thunderstorms to drought-stricken parts of New Zealand,[74] with reports of up to 112 mm at Turakina near Whanganui and a tornado in New Plymouth.

[79][80][81] On January 7, Tropical Disturbance 07F developed near an upper level low, in area of moderate vertical windshear about 800 km (495 mi) to the northeast of Papeete on Tahiti Island in French Polynesia.

[83][84] On January 26, RSMC Nadi reported that Tropical Disturbance 10F had developed within an area of moderate vertical wind shear about 80 km (50 mi) to the east of the Duff Islands.

[89][90] As the final warning on 12F was issued, RSMC Nadi reported that Tropical Disturbance 13F had developed under an upper level ridge of high pressure in an area of moderate vertical windshear, about 360 km (225 mi) to the northeast of Suva, Fiji.

[91][92] Over the next couple of days the system moved slowly westwards and impacted Fiji, with heavy rain and squally thunderstorms which led to localised flooding being reported in various places on Viti Levu.

[92][93] On March 12, Tropical Disturbance 18F developed within an area of moderate vertical windshear, underneath an upper level ridge of high pressure about 465 km (290 mi) to the north of Suva, Fiji.
