Several islands within the Solomon Islands reported extensive property and crop damage. Within Vanuatu, Anne brought heavy rains, flooding, and a storm surge. These effects damaged houses, crops, and property, especially on Ureparapara islands and the Torres Islands. Extensive damage was reported in New Caledonia after it was exposed to a prolonged period of storm force winds, with the eastern and southern coasts particularly affected. On January 12, the system produced the highest daily rainfall totals since 1951 in several areas. Two people were killed after they attempted to cross a flooded river, and about 80 others were injured by the cyclone. Due to the impact of this storm, the name Anne was retired.

Meteorological history

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. 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. As the system 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 reported that the system had become equivalent to 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 moved through Temotu Province and passed about 55 km (35 mi) to the northwest of Anuta Island.

Later on January 10, Anne passed directly over Vanuatu's Torres Islands and came within 65 km (40 mi) of Ureparapara in the Banks Islands. The cyclone continued to move to the south-southwest and affected the northern islands of Vanuatu. Early on January 11, the FMS reported that Anne had peaked, with estimated 10-minute sustained winds near its center of 185 km/h (115 mph), equivalent to a Category 4 severe tropical cyclone on the Australian scale. Around the same time, the JTWC reported that Anne had peak 1-minute sustained winds of 260 km/h (160 mph), which made it equivalent to a Category 5 hurricane on the SSHWS. This made it one of the most intense tropical cyclones of the 1980s. Over the next day, Cyclone Anne turned south and rapidly weakened as it encountered upper-level wind shear, approaching the French overseas territory of New Caledonia. Late on January 12, Anne weakened into a modern-day Category 2 tropical cyclone before it made landfall on New Caledonia about 110 km (70 mi) to the north-northwest of Nouméa. After the cyclone re-emerged into the Coral Sea, the system started to interact with Cyclone Agi, which had rapidly moved south-eastward towards the "relatively deeper" Anne. Agi had developed two days prior near the Louisiade Archipelago, about 1,200 km (745 mi) northwest of Cyclone Anne. Early on January 14, Anne weakened into a depression before dissipating to the southeast of New Caledonia, after it was caught up in the upper westerly flow.
