1984–85 South Pacific cyclone season
The 1984–85 South Pacific cyclone season was an above-average tropical cyclone season, with nine tropical cyclones occurring within the basin between 160°E and 120°W. The season ran from November 1, 1984, to April 30, 1985, with tropical cyclones officially monitored by the Fiji Meteorological Service (FMS), Australian Bureau of Meteorology (BoM) and New Zealand's MetService. The United States Joint Typhoon Warning Center (JTWC) and other national meteorological services including Météo-France and NOAA also monitored the basin during the season. During the season there was nine tropical cyclones occurring within the basin, including three that moved into the basin from the Australian region. The BoM, MetService and RSMC Nadi all estimated sustained wind speeds over a period of 10-minutes, which are subsequently compared to the Australian tropical cyclone intensity scale, while the JTWC estimated sustained winds over a 1-minute period, which are subsequently compared to the Saffir–Simpson hurricane wind scale (SSHWS).
During November and December no significant tropical cyclones developed in or moved into the basin in the region,
The remnants of Tropical Cyclone Pierre were last noted during 24 February, as they moved into the basin from the Australian region.
An unnamed tropical cyclone existed from December 26 to December 28.
Tropical Cyclone Monica existed from December 29 to December 30.
Tropical Cyclone Drena existed from January 9 to January 16.
On January 13, TCWC Nadi started to monitor a shallow depression that had developed within the monsoon trough about 725 km (450 mi) to the west of Espiritu Santo, Vanuatu. Over the next day the system moved eastwards and developed further as gale-force winds developed near the systems centre before the JTWC initiated advisories on the system and designated it as Tropical Cyclone 11P during January 14. The system was subsequently named Eric by TCWC Nadi as it moved closer to Espiritu Santo and became equivalent to a category 1 tropical cyclone. During January 15, Eric passed near or over Espiritu Santo, as it continued to intensify before it turned and accelerated south-eastwards. Eric subsequently became equivalent to a category 3 severe tropical cyclone early the next day, before an Air Pacific flight from Fiji to the Solomon Islands located the systems eye on radar.
During January 17, Eric's well defined eye came into the range of Nadi airports surveillance radar, before TCWC Nadi estimated that Eric had peaked with 10-minute sustained wind-speeds of 150 km/h (90 mph). During that day Eric's eye seemed to contract to around 15 km (10 mi) as it made passed through Fiji's Western Division and made landfall on the Fijian main island of Viti Levu about 10 km (5 mi) to the south of Nadi. After the system had made landfall, the JTWC estimated that Eric had peaked with 1-minute sustained wind speeds of 185 km/h (115 mph), which made it equivalent to a category 3 hurricane on the SSHWS.The system subsequently passed near or over Fiji's capital: Suva before emerging into the Korro Sea and weakening. Eric subsequently passed through the Tonga's Ha'apai islands just to the south of Nomuka during January 18, before it gradually weakened and was last noted during January 20, over 1,800 km (1,120 mi) to the south of Papeete, French Polynesia.
