Pacific Hurricane Naming Lists (Hitman)

Within the Eastern Pacific Ocean, there are two warning centers that assign names to tropical cyclones on behalf of the World Meteorological Organization when they are judged to have intensified into a tropical storm with winds of at least 34 kn (39 mph; 63 km/h). Tropical cyclones that intensify into tropical storms between the coast of Americas and 140°W are named by the National Hurricane Center (NHC/RSMC Miami), while tropical cyclones intensifying into tropical storms between 140°W and 180° are named by the Central Pacific Hurricane Center (CPHC/RSMC Honolulu). Significant tropical cyclones have their names retired from the lists and a replacement name selected at the next World Meteorological Organization Hurricane Committee.

The current naming scheme began with the 1978 season, one year before the Atlantic basin (and which anomalously used the list that will be used next in 2018, rather than the one for 2020). As with the Atlantic basin, it uses alternating women's and men's names, and also includes some Spanish and a few French names. Before then, only women's names were used. Because Eastern Pacific hurricanes mainly threaten western Mexico and Central America, the lists contain more Spanish names than the Atlantic lists.

Central North Pacific Ocean (140°W to 180°)
When a tropical depression intensifies into a tropical storm to the north of the Equator between 140°W and 180°, it is named by the CPHC. Four lists of Hawaiian names are maintained by the World Meteorological Organization's hurricane committee, rotating without regard to year, with the first name for a new year being the next name in sequence that was not used the previous year. The names of significant tropical cyclones are retired from the lists, with a replacement name selected at the next Hurricane Committee meeting.
