Timeline of the 2006–07 South Pacific cyclone season
The 2006–07 South Pacific cyclone season was a below-average season with six tropical cyclones forming to the east of 160E.[A 1] The season officially ran from November 1, 2007 to April 30, 2008, although the first cyclone, Severe Tropical Cyclone Xavier, formed on October 20.
Within this basin, tropical cyclones are monitored by the Regional Specialized Meteorological Center (RSMC) in Nadi, Fiji, and the Tropical Cyclone Warning Center (TCWC) in Wellington, New Zealand. RSMC Nadi attaches an F suffix to tropical disturbances that either form or move into the South Pacific. The United States' Joint Typhoon Warning Center (JTWC) issues unofficial warnings for this basin, designating tropical cyclones with a number and a P suffix. RSMC Nadi and TCWC Wellington both use the Australian Tropical Cyclone Intensity Scale, and measure windspeeds over ten minutes whilst the JTWC measures windspeeds over a minute and uses the Saffir–Simpson Hurricane Scale.
This timeline includes information that was not operationally released, meaning that information from post-storm reviews by RSMC Nadi, TCWC Wellington and the JTWC has been included. It documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season. Reports among warning centers often differ; as such, information from all three agencies has been included.
