Tropical Storm Kammuri (2008) - Meteorological History

Meteorological History

On August 3 at 1500 UTC, PAGASA identified a tropical disturbance which was located in the South China Sea to the north of Luzon island in the Philippines and designated it as Tropical Depression Julian. Later that day the Japan Meteorological Agency (JMA) designated Julian as a minor tropical depression and initiated advisories on the tropical depression.

Early the next day the JMA started to issue full advisories on the tropical depression. The Joint Typhoon Warning Center (JTWC) then started to issue warnings on the tropical depression later that day with them designating it as Tropical Depression 10W. Furthermore, later that day both PAGASA and the JTWC upgraded the tropical depression to a tropical storm.

On August 5, the JMA upgraded the depression to a tropical storm and named it Kammuri, whilst PAGASA released their final advisory on Tropical Storm Kammuri (Julian) later that day as it moved out of their Area of Responsibility and headed towards mainland China. The Hong Kong Observatory (HKO) then upgraded Kammuri to a severe tropical storm late on August 5, with the JMA doing the same early the next morning.

However, Kammuri started to weaken after making landfall along the south coast of China in the Western Guangdong Province at about 12pm UTC on August 6. After Kammuri had made landfall the JMA downgraded Kammuri to a tropical storm, whilst the JTWC issued their final advisory later that day on Tropical Storm Kammuri. Early the next day Tropical Storm Kammuri emerged into the Gulf of Tonkin, however later that day Kammuri made landfall again in the Guangxi province of China. After making landfall for the second time on August 7 Kammuri weakened to a tropical depression as the JMA issued its final advisory. However the JMA continued to monitor the depression in their WWJP25 warnings until early on August 8.
