2011-12 South Pacific cyclone season

The 2011–12 South Pacific cyclone season is the current period of tropical cyclone formation within the South Pacific Ocean to the east of 160°E. The season officially runs from November 1, 2011 to April 30, 2012. However, any tropical cyclones that form between July 1, 2011 and June 30, 2012 will count towards the season total.

Within the South Pacific, 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 a number and an F suffix to tropical disturbances that form in or move into the South Pacific. The United States Joint Typhoon Warning Center (JTWC) issues unofficial warnings within the South Pacific, 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 wind speeds over a period of ten minutes, while the JTWC measures sustained winds over a period of one minute and uses the Saffir–Simpson Hurricane Scale.
