Tropical Cyclone Zelia
● 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).
Zelia at 1998-10-06 08:00:00 (BeijingTime) 在South Indian Ocean首次被记录, peak intensity 为Category 1 Tropical Cyclone , max wind 约 23.1 m/s (1 分钟平均) , minimum central pressure 990 hPa, at 1998-10-10 20:00:00前后结束, total 记录 19 track points (6 h一个) .
