On October 11, 2020, the Japan Meteorological Agency (JMA) began tracking a tropical depression off the west coast of Luzon.[1] The PAGASA declared the system as a tropical depression at 12:00 UTC, and since the storm formed inside of the Philippine Area of Responsibility (PAR) the agency named the system Nika.[2] On the same day at 21:00, the Joint Typhoon Warning Center began issuing warnings on the system.[3] On October 12, the system was declared a tropical storm by the JMA, and was named Nangka.[4] At 9:00, the system left the PAR and the PAGASA issued its final bulletin on the system.[5] At 19:20 CST (11:20 UTC) on October 13, Nangka made landfall over Qionghai, Hainan.[6] The system continued tracking westward, returning to open water, before making a second landfall in Ninh Bình, Vietnam on October 14. As the system tracked further inland, it dissipated over Laos on the same day.[7][8]
