Typhoon Cempaka

Typhoon Cempaka was a moderately-strong, slow-moving and fairly long-lived tropical cyclone that caused substantial damage in China and Vietnam toward the end of July 2021. The seventh named storm and the fourth typhoon of the 2021 Pacific typhoon season, the storm formed from a tropical disturbance west of the Philippines on July 17. Around the same time, the JMA recognized the system as a tropical depression, with the JTWC issuing a TCFA for the disturbance. The storm slowly moved northwestward towards China, and on July 19, the system strengthened into a tropical storm and was given the name Cempaka by the JMA. On the next day, Cempaka reached its peak intensity, peaking as a Category 1-equivalent typhoon, before making landfall on China later that day. Afterward, Cempaka rapidly weakened as it moved inland, weakening into a tropical depression on July 21. The storm subsequently initiated a counterclockwise loop, moving westward across southern China, and turning southward and emerging into the Gulf of Tonkin on July 23. Afterward, Cempaka turned eastward for the next few days, before dissipating over southern Hainan on July 26. At 18:00 UTC on July 16, the Japan Meteorological Agency (JMA) started to monitor a tropical disturbance that formed in the South China Sea, west of the Philippines. Moving westward and later to the west-northwest, the system further intensified to a tropical depression and was designated as Invest 99W by the Joint Typhoon Warning Center (JTWC) two hours later, with its development chances being "low".
