2007–08 South Pacific cyclone season

[4][page needed] During October 2007, both RSMC Nadi and New Zealand's National Institute of Water and Atmospheric Research (NIWA), issued forecasts for a near to below average season, due to the presence of a weak La Niña event.

[8] Over the next few days, the depression moved slowly towards the east, before RSMC Nadi issued their final advisory on 01F early on October 19, as it had become sheared and had weakened into a tropical low.

RSMC Nadi also reported during November 22, that a weak tropical disturbance had developed on the edge of the basin about 280 km (175 mi) to the south of Honiara, on the Solomon Island of Guadalcanal.

[12] However convection surrounding the system was poorly organized and remained so over the next couple of days, as it moved southwards into an area of high vertical windshear and cooler sea surface temperatures.

[11][14] On November 22, RSMC Nadi reported that a weak tropical disturbance had developed on the edge of the basin, about 285 km (175 mi) to the south of Honiara on the Solomon Island of Guadalcanal.

Over the next couple of days the depression moved towards the east and gradually developed further before RSMC Nadi designated it as Tropical Disturbance 03F on November 24, while it was located about 400 km (250 mi) to the northeast of Port Vila on the Vanuatuan island of Efate.

On December 5, as the depression moved towards the west into the Fijian archipelago, both the Joint Typhoon Warning Center (JTWC) and RSMC Nadi upgraded it to Cyclone Daman.

[16] Early on December 11, RSMC Nadi reported that Tropical Depression 05F had developed within a surface trough, about 670 km (415 mi) to the northeast of Apia on the Samoan Island of Upolu.

The depression was then last noted by RSMC Nadi on December 14, as it and the high-pressure system started to weaken after causing gale-force winds, flooding and significant swells.

On December 26, RSMC Nadi reported that Tropical Disturbance 06F had developed about 680 km (420 mi) to the northeast of Avarau on the Southern Cook Island of Rarotonga in an area of high vertical windshear.

[22] At 1800 UTC on January 7, RSMC Nadi reported that a poorly organized Tropical Depression 07F, had developed within a slow moving trough of low pressure about 600 km (370 mi), to the east of Suva, Fiji.

[16][23] During January 11, Elisa recurved towards the southeast into a region of cooler waters and stronger windshear, as a result the cyclone weakened into a depression, with RSMC Nadi and the JTWC issuing their final advisories later that day.

[28][29] On February 15, RSMC Nadi and the JTWC reported that a tropical depression had developed within a monsoon trough, about 700 km (435 mi) to the northeast of Port Vila on the Vanuatuan island of Efate.

[1][31] [32] It then started to move eastwards and passed very near the next day to the northern tip of Aurora Island, Vanuatu with wind speeds of 55 knots (102 km/h) which made Funa a category two cyclone on the Australian scale.

[27] On January 26, RSMC Nadi and the JTWC started to monitor a weak tropical disturbance that had developed within a monsoon trough about 290 km (180 mi) to the northeast of Rotuma.

[1][41] At 1800 UTC on January 27, the JTWC reported that the disturbance had developed into Tropical Cyclone 15P, while it moved towards the southwest and hugged Vanua Levu's southeastern coast, under the influence of a ridge of high pressure that was located to the southeast of the system.

[48] On March 21, The Depression encountered an unfavourable environment of moderate to high vertical wind shear and weakened with the JTWC issuing its final advisory that day.

[51][52] On April 4, RSMC Nadi reported that Tropical Disturbance 15F had developed within the Australian region, about 415 km (260 mi) to the north-northeast of New Caledonia's Chesterfield Islands.

[53] The system subsequently moved south-eastwards and passed between Vanuatu and New Caledonia, before it was last noted on April 7, while it was located about 750 km (465 mi) to the northeast of Norfolk Island.

Despite anticipation that tropical cyclogenesis was unlikely in the short term, deep convection rapidly developed over an increasingly better defined circulation, with an anticyclone aloft aiding in intensification.
