. The depression had picked up convection during the previous 24 hours and organized with an upper anticyclonic circulation lying to the west of the depression. During the following 24 hours the system lost some of its organization as deep convection had decreased with RSMC Nadi issuing its final advisory early on July 5 as it approached the edge of its area of responsibility.

Despite being the first tropical depression of the 2002-03 tropical cyclone year, it was numbered using the last number from the previous tropical cyclone year. The reasons for this are not known.

Severe Tropical Cyclone Zoe

A depression formed at the end of December. It quickly strengthened into one of the most intense tropical cyclones ever recorded with 10-minute average sustained winds of 130 knots. It eventually went extratropical.

Zoe caused catastrophic damage on several small islands in the south Pacific. There were no direct fatalities. Crops were heavily disrupted and took several years to recover. The name Zoe was later retired.

 less than two months prior. The storm brought torrential rains and high winds that triggered landslides. Dozens of homes were damaged and many of the newly planted gardens in the recovery phase of Cyclone Zoe were destroyed. The impacts of Gina reportedly set back the recovery efforts for Zoe by nearly six months. A total of 112 newly-built houses and 128 newly-built kitchens were severely damaged and another 37 homes sustained minor damage. The newly planted winter crop was lost due to sea spray and 143 bags of rice, given as relief supplies from Cyclone Zoe, were lost. Following the storm, additional relief supplies and food were rushed to residents to ensure their safety. The new relief materials consisted of local foods, sago and mesh wiring, worth $14,400.
