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 1990-08-20 08:00:00 (BeijingTime) 在North Indian Ocean首次被记录, peak intensity 为Depressions, max wind 约 14.4 m/s (1 分钟平均) , minimum central pressure 986 hPa, at 1990-08-25 02:00:00前后结束, total 记录 20 track points (6 h一个) . 曾Landfall或贴近land.

There is no official Chinese name for this system, so the original English name is used. Intensity categories follow the classifications of the relevant regional agency, converted from 1-minute sustained wind using the WMO factor, for reference only. Data notes · Incorrect translation?
