Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 1987065S11164 / SH221987. There is no official Chinese name for this system, so the original English name is used. Intensity is classified according to the local agency in the region (converted from 1-min sustained winds using the WMO factor), for reference only. Data notes · Incorrect translation?
