East China Sea: Tropical Storm Jongdari tracking northward across East China Sea as of early Aug. 20 /update 1
TS Jongdari tracks northward over East China Sea early Aug. 20. Close approach to Jeju Island, South Korea, likely.
Tropical Storm Jongdari is tracking northward across the East China Sea early Aug. 20. As of 12:00 KST, the system's center of circulation was approximately 531 km (330 miles) south of Kunsan Air Base, North Jeolla Province, South Korea.
Forecast models indicate that the weather system will weaken into a tropical depression as it continues northward and makes a close approach to Jeju Island, South Korea, the evening of Aug. 20, passing just west of the island before tracking northward along the coast of western South Korea through early Aug. 21. Jongdari is forecast to make landfall as a tropical depression over Incheon Metropolitan City, South Korea, early Aug. 21 before weakening rapidly and dissipate as it tracks north-northeastward across far eastern South Hwanghae, eastern North Hwanghae, far southeastern South Pyongan, then western South Hamgyong provinces in North Korea through late Aug. 21. Some uncertainty remains in the track and intensity forecast, and changes could occur in the coming days.
As of early Aug. 20, the Korea Meteorological Administration has issued a typhoon warning (higher-level on a two-tier scale) for the outer offshore waters of Jeju Island. Typhoon advisories are in place for the rest of the waters southwest of South Korea. Authorities will likely issue new warnings or update existing advisories throughout the system's progression in the coming days.
Sustained heavy rainfall could trigger flooding in low-lying areas and those with easily overwhelmed drainage systems. If weather conditions prove hazardous, localized evacuations, flash flooding, and landslides are possible.
The inclement weather could trigger localized business, transport, and utility disruptions and render some bridges or roadways impassable. Flight disruptions at regional airports and temporary closures of ports are also possible. Stagnant pools of water during and after flooding increase insect- and waterborne diseases, such as dengue fever, cholera, and malaria. Exposure to raw sewage and other hazardous materials mixed with floodwaters poses a serious health threat.
Activate contingency plans in areas where officials forecast tropical storm conditions. Heed any evacuation orders that may be issued. Use extreme caution in low-lying coastal areas and near streams, creeks, and other waterways due to the potential for severe flooding and storm surge. Stockpile water, batteries, and other essentials in advance. Charge battery-powered devices when electricity is available; restrict the use of cellular phones to emergencies only. Power down mobile devices when not in use. Keep important documents and necessary medications in waterproof containers. Observe strict food and water precautions, as municipalities could issue boil-water advisories following flooding events. Take precautions against insect- and waterborne diseases in the coming weeks.
Plan accordingly for protracted commercial, transport, and logistics disruptions in areas in the path of the storm, especially if vital infrastructure is damaged. Seek updated information on road conditions before driving or routing shipments through areas where flooding has occurred. Confirm flights before checking out of hotels or driving to the airport; clearing passenger backlogs may take several days in some locations.
