The 1987 Unnamed 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 1987-10-14 08:00:00 (BeijingTime) 在North Indian Ocean首次被记录, peak intensity 为The Cyclone Storm, max wind 约 23.1 m/s (1 分钟平均) , minimum central pressure 994 hPa, at 1987-10-19 20:00:00前后结束, total 记录 23 track points (6 h一个) . 曾Landfall或贴近land.
