Severe Tropical Cyclone Gene (RSMC Nadi designation:12F JTWC designation:15P) was the deadliest storm as well as the most damaging tropical cyclone of the 2007–08 South Pacific cyclone season

 and was designated as Tropical Disturbance 12F. The next day it was upgraded to a tropical depression, whilst on January 27, RSMC Nadi named the depression as Cyclone Gene. Later that day Gene made landfall on Fiji, and caused 8 deaths and $51 million (2008, F$). Cyclone Gene then slowly intensified to a category three cyclone on both the Saffir Simpson Hurricane Scale and the Australian Cyclone Intensity Scale. Gene then took a turn to the south moving towards 25°S which marks the edge of RSMC Nadi's area of responsibility with the Tropical Cyclone Warning Centre (TCWC) in Wellington

 (RSMC) in Nadi, Fiji, designated the area of low pressure as a tropical disturbance. The next day the Joint Typhoon Warning Center assessed its chances of forming in to a significant tropical cyclone within the next 24 hours as poor. Later that day the JTWC reassessed the disturbances chances of becoming a significant tropical cyclone within 24 hours as fair, this was because the low level circulation center

 was poorly organised. RSMC Nadi then noted that the disturbance had become more organised and, thus the disturbance was upgraded to Tropical Depression 12F. They also assessed the depressions potential of forming in to a tropical cyclone within 24 hours as low. Later that evening as an Anticyclone had helped to develop the disturbance the JTWC upgraded the disturbances chances of forming in to a significant tropical cyclone to good and issued a Tropical Cyclone Formation Alert

 and assigned the name Gene to the cyclone. At the same time the JTWC issued their first warning on Gene and designated it as tropical cyclone 15P.

. Gene briefly weakened as it encountered the effects of moderate vertical wind shear

. However, this weakening trend was short-lived, as environmental conditions improved, allowing Gene to intensify further; it became a severe tropical cyclone on January 30. On January 31, while the storm was moving closer to Vanuatu, Gene attained peak winds of 150 km/h (95 mph10 min) & 185 km/h (115 mph 1-min) Thus, Cyclone Gene was a Category 3 cyclone on the Australian scale and the Saffir-Simpson Hurricane Scale

.

During February 1, as Cyclone Gene was moving to the west, Gene recurved and started moving towards the south and missed Vanuatu. The next day cyclone Gene started to temporarily weaken again by becoming a category two cyclone with winds speeds of 95 km/h (60 mph 10 min). This came as cyclone Gene approached 25°S which marks the edge of RSMC Nadi's area of responsibility, to the south of 25°S the Tropical Cyclone Warning Centre (TCWC) in Wellington, New Zealand monitors tropical cyclones, south of 25°S. As Gene crossed in to TCWC Wellington's area of responsibility, Cyclone Gene started to re-intensify becoming a severe tropical cyclone again with peak winds of 120 km/h (105 mph 10 min) however this re-intensification only lasted for 12 hours before Gene began to weaken for the final time by becoming a tropical cyclone that day. Gene slowly weakened over the next couple of days as it moved towards the south east. The JTWC then issued its final warning on February 6 as Cyclone Gene was finishing its extratropical transition, and had also become fully embedded within the baroclinic zone. However TCWC Wellington kept releasing advisories on extratropical Gene, until they released their final advisory on February 9.

an government. There was also 61 houses completely flattened by cyclone Gene.

The effects of Cyclone Gene were compounded by continuous heavy rainfall and subsequent floods in most parts of Viti Levu. As a result there was significant disruption to water supplies, with several sources becoming contaminated and destroyed as a result there were several cases of Typhoid reported in Fiji with at least 1 person dying from typhoid. There was also seven other deaths from cyclone Gene, five of these were directly related whilst two people were also killed as an indirect result of Cyclone Gene from house fires while using candles to light their homes when the power went out. Within their end of season report RSMC Nadi reported that the total cost of Cyclone Gene was F$51 million (2008), ($35 million 2008 USD).
