Unnamed North Indian Ocean cyclone of 1998
● 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).
未命名 at 1998-05-27 14:00:00 (BeijingTime) 在North Indian Ocean首次被记录, peak intensity 为Deep Depression, max wind 约 18 m/s (1 分钟平均) , at 1998-05-29 08:00:00前后结束, total 记录 8 track points (6 h一个) .
