 On January 5, 1988, the Fiji Meteorological Service (FMS) started to monitor a shallow tropical depression that developed within the monsoon trough about 540 km (335 mi) northeast of Tuvalu. At around the same time, a twin depression developed within the Northern Hemisphere monsoon trough, which eventually became Typhoon Roy. Over the next two days the Southern Hemisphere system developed further as it was steered towards the south-southwest along an area of high pressure, before it became equivalent to a tropical storm while passing through the Tuvaluan islands. As a result, the United States Joint Typhoon Warning Center (JTWC) designated the system as Tropical Cyclone 07P and started to issue advisories on it. After organized further, the FMS named the storm Anne after it became equivalent to a modern-day Category 2 on the Australian tropical cyclone intensity scale. On January 9, the cyclone started to rapidly intensify while continuing to move towards the south-southwest. Later that day, the JTWC upgraded the system to the equivalent of a Category 1 on the Saffir – Simpson hurricane wind scale (SSHWS), and the FMS upgraded Anne to a Category 3 severe tropical cyclone on the Australian Scale. Early on January 10, the cyclone passed through Temotu Province and about 55 km (35 mi) to the northwest of Anuta Island.
