Philippines: Tropical Storm 9 has formed and is tracking northwestward across the Philippine Sea, northeast of Luzon, Philippines, as of early Aug. 24

Event

Tropical Storm 9 (known in the Philippines as Goring) has formed and is tracking northwestward across the Philippine Sea, northeast of Luzon, Philippines, early Aug. 24. As of 11:00 PHT, the storm's center of circulation was approximately 770 km (479 miles) south-southwest of Kadena Air Base, Okinawa Prefecture, Japan.

Forecast models indicate the system will remain northeast of Luzon, Philippines, as it strengthens into a typhoon while gradually turning to track northeastward through early Aug, 29. The storm is forecast to strengthen as it continues northwestward through late Aug. 24 before making a sharp turn to track westwards through early Aug. 25. The system is forecast to make another sharp turn to track southwards and strengthen further into a typhoon through early Aug. 27. The system is likely to gradually turn to track northeastward while maintaining its strengthen through early Aug. 29. The storm's track and intensity forecast remains somewhat uncertain, and the system may change accordingly over the coming days.

The Philippine Atmospheric, Geographical, Astronomical Services Administration (PAGASA) has warned that heavy rainfall over portions of Cagayan Valley Region is possible over the coming days. Authorities may issue new warnings or update existing advisories throughout the system's progression in the coming days. Weather warnings could remain active even after the system's immediate threat has diminished, as some areas may still be highly susceptible to rain-induced hazards.

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 may increase the incidence of 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.

Advice

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.
