Hurricane Allison
● 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).
Allison at 1989-06-25 02:00:00 (BeijingTime) 在North Atlantic首次被记录, peak intensity 为Tropical Storm, max wind 约 23.1 m/s (1 分钟平均) , minimum central pressure 999 hPa, at 1989-07-01 20:00:00前后结束, total 记录 28 track points (6 h一个) . 曾Landfall或贴近land.

Data sources: NOAA National Centers for Environmental Information IBTrACS v04r01 (Knapp et al., 2010), code 1989176N27264 / AL021989. There is no official Chinese name for this basin, so the original English name is used. Intensity is classified by the local agency for the basin, converted from 1-min sustained wind using the WMO factor, for reference only. Data notes · Incorrect translation?
