Data sources: NOAA National Environmental Information Center IBTrACS v04r01 (Knapp et al., 2010); code 2019337S04065 / SH032020. There is no official Chinese name for this system, so its English name is used. Intensity grades follow the classifications of the local agency in the region, converted from 1-minute sustained winds using the WMO factor, and are for reference only.
