 These dates conventionally delimit the period of each year when most tropical cyclones form in the southern Pacific Ocean east of 160°E.Additionally, the regional tropical cyclone operational plan defines a "tropical cyclone year" separately from a "tropical cyclone season", and the "tropical cyclone year" runs from July 1, 2006 to June 30, 2007.Tropical cyclones between 160°E and 120°W and north of 25°S are monitored by the Fiji Meteorological Service in Nadi.
