Unnamed 1990 North Indian Ocean Cyclone
● 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 1990-10-31 02:00:00 (BeijingTime) 在North Indian Ocean首次被记录, peak intensity 为Depressions, max wind 约 15.4 m/s (1 分钟平均) , minimum central pressure 1001 hPa, at 1990-11-04 20:00:00前后结束, total 记录 20 track points (6 h一个) . 曾Landfall或贴近land.
