Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010), code 2004338S09113 / SH052005. There is no official Chinese name for this system, so the original English name is shown. Intensity grades are based on the classifications of the local agency in the affected waters (converted from 1-min sustained wind using the WMO factor), for reference only.
