Severe Tropical Cyclone Ivy (Fiji Meteorological Service designation: 05F, Joint Typhoon Warning Center designation: 13P) was a tropical cyclone that affected about 25% of the population of Vanuatu in February 2004. It was first classified as a tropical disturbance on February 21 between Vanuatu and Fiji. The system tracked northwestward, gradually organizing and intensifying. After attaining tropical storm status on February 23, Ivy strengthened more quickly as it turned southwestward toward Vanuatu. It attained peak winds of 165 km/h (105 mph) while moving over Vanuatu, making it an intense Category 4 cyclone on the Australian Region Tropical Cyclone Intensity Scale. By the time it passed through Vanuatu, Ivy had turned southeastward, and it gradually weakened while accelerating. After becoming extratropical on February 28, it passed just east of New Zealand and eventually dissipated on March 2.
