Philippine Sea: Typhoon Hinnamnor tracking westwards across the Philippine Sea early Aug. 30
Typhoon Hinnamnor tracking westwards across the Philippine Sea early Aug. 30. Close approach to Okinawa Prefecture, Japan Aug. 31.
Event
Typhoon Hinnamnor is tracking westwards over the Philippine Sea as of early Aug. 30. As of 12:00 JST, the system's center of circulation was approximately 448 km (278 miles) west-northwest of Iwo Jima, Japan.
Forecast models indicate that the storm will strengthen further into a super typhoon by the evening of Aug. 30 while continuing to track westwards. Hinnamnor is likely to make a close approach as a super typhoon to Okinawa Prefecture, Japan Aug. 31 before turning to track southwestwards along the prefecture through early Sep. 2 while weakening into a typhoon. The storm is forecast to make a sharp turn to track northwards early Sep. 2 before making a close approach and passing east of Miyako Island, early Sep. 4. Some uncertainty remains in the track and intensity forecast, and significant changes could occur in the coming days.
As of early Aug. 30, the Japan Meteorological Agency has not yet issued any watches and warnings in relation to the storm but has warned of large waves, storms, and swells across the Okinawa region Aug. 31. Thunderstorms and heavy rainfall of 20-30 cm (8-12 inches) are forecast over the Okinawa region Aug. 31 through early Sep. 1. Officials could update and possibly extend the coverage of the relevant weather alerts over the coming days as the system progresses.
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. 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.
