Tropical Cyclone Hinano
● Data reliability: ReliableWeather satellites monitored it throughout, so its track and intensity are relatively accurate (Atlantic and E. Pacific since 1966, other basins since 1980).
Hinano at 1989-02-21 08:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Category 3 tropical cyclone , max wind 约 46.3 m/s (1 分钟平均) , minimum central pressure 970 hPa, at 1989-03-01 08:00:00前后结束, total 记录 33 track points (6 h一个) .
