1998–99 South Pacific cyclone season
Encyclopedia
The 1998–99 South Pacific cyclone season was a near average tropical cyclone seasons, with 8 tropical cyclones occurring within the South Pacific Ocean basin between 160°E
and 120°W
. Despite the season starting on November 1, the first tropical system of the season did not form until December 1, while the final disturbance of the season dissipated on May 27, 1999. During the season the most intense tropical cyclone was Severe Tropical Cyclone Cora, which had a minimum pressure of 930 hPa (27.5 inHg). After the season had ended the names Cora and Dani were retired from the naming lists, after they had caused significant impacts to South Pacific islands.
During the season, tropical cyclones were officially monitored by the Regional Specialized Meteorological Center
(RSMC) in Nadi, Fiji
and the Tropical Cyclone Warning Center in Wellington, New Zealand
. While the United States Navy also monitored the basin and issued unofficial warnings throughout the season, through its Joint Typhoon Warning Center
(JTWC) and Naval Pacific Meteorology and Oceanography Center (NPMOC). Tropical cyclones that were located between 160°E and 120°W
as well as the Equator and 25S were monitored by TCWC Nadi while any that were located to the south of 25S between 160°E and 120°W were monitored by TCWC Wellington. During the season the JTWC issued warnings on any tropical cyclone that was located between 160°E and the 180°
while the NPMOC issued warnings for tropical cyclones forming between 180° and the American coast. RSMC Nadi and TCWC Wellington both used the Australian tropical cyclone intensity scale, and measured windspeeds over a 10-minute period, while the JTWC and the NPMOC measured sustained windspeeds over a 1-minute period. For the first time this season, RSMC Nadi assigned a number and the letter F to each significant tropical disturbance that moved within the South Pacific basin, while the JTWC and NPMOC continued to assign a number and the letter P to significant tropical cyclones throughout their area of responsibility.

. As soon as a tropical depression becomes a tropical cyclone it is named by the warning centre having responsibility for it at that time. If a tropical depression becomes a tropical cyclone in the Wellington RSMC area of responsibility, MetService
, in consultation with RSMC Nadi, will name the cyclone by using the next name from the list.
They were replaced by the names Colin and Donna.
