Hurricane Hallie
● 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).
Hallie at 1975-10-24 02:00:00 (BeijingTime) 在North Atlantic首次被记录, peak intensity 为Tropical Storm, max wind 约 23.1 m/s (1 分钟平均) , minimum central pressure 1002 hPa, at 1975-10-28 08:00:00前后结束, total 记录 18 track points (6 h一个) .
