Philippine Sea: Tropical Storm Doksuri tracking west-northwestward east of the Philippines as of July 22

Event

Tropical Storm Doksuri (known in the Philippines as Egay) is tracking west-northwestward in the Philippine Sea east of the Philippines July 22. As of 11:00 CST, the system's center of circulation was approximately 1,547 km (961 miles) southeast of Taipei, Taiwan. Forecast models indicate that the storm will continue tracking west-northwestward and intensify into a typhoon through July 23. Doksuri is forecast to shift to a northwestward trajectory beginning July 24 and make a close approach to northern Taiwan July 27. Uncertainty remains in the track and intensity forecast, and significant changes could occur in the coming days.

As of July 22, officials have yet to issue any related weather advisories. Authorities will likely issue new warnings throughout the system's progression in the coming days. Rainfall totals of 5-10 cm (2-4 inches) are forecast across parts of Catanduanes Province in the Bicol Region of Luzon, Philippines, July 24. Strong winds are also possible over Bicol Region and parts of Eastern Visayas. Large waves reaching 2-3 m (7-10 feet) are possible across the eastern coasts of southern Luzon, the Visayas, and Mindanao from July 23.

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.

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.
