Tropical Cyclone Hettie
● 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).
Hettie at 2009-01-25 08:00:00 (BeijingTime) 在South Pacific首次被记录, peak intensity 为Tropical Depression, max wind 约 18 m/s (1 分钟平均) , minimum central pressure 995 hPa, at 2009-01-30 02:00:00前后结束, total 记录 20 track points (6 h一个) .
