HAZARDS AFFECTING COASTAL WATERS

24-Hour Sea Condition Outlook

OPONG may bring moderate to rough seas over the coastal waters of Eastern Visayas and northeastern Mindanao starting Thursday afternoon. Gale Warning may be raised over Eastern Visayas and Bicol Region as early as Thursday afternoon in anticipation of rough to very rough sea conditions.

Coastal Inundation

There is a potential risk of coastal flooding due to storm surge in low-lying coastal areas of Southern Luzon and Eastern Visayas due to the passage of OPONG. Storm surge warning may be issued starting either tomorrow (24 September) or on Thursday (25 September).

TRACK AND INTENSITY OUTLOOK

• OPONG is forecast to move generally west southwestward within the next 12 hours before turning west northwestward while approaching Eastern Visayas – Southern Luzon area. On the forecast track, OPONG may make landfall over Bicol Region by Friday (26 September) and is expected to cross Southern Luzon area from Friday afternoon until Saturday (27 September) morning. It may exit the Philippine Area of Responsibility by Saturday evening or Sunday (28 September) morning.
• It must be emphasized that heavy rainfall, severe winds, and storm surge may still be experienced in localities outside the landfall point and the forecast confidence cone. Refer to “Other Hazards affecting Land Areas” for more details. Furthermore, the track may still shift within the limit of the forecast confidence cone.
• OPONG will continue to intensify while over the Philippine Sea and may reach severe tropical storm category by Thursday (25 September) afternoon. Further intensification, especially after the passage over the Philippine landmass, is not ruled out.

Considering these developments, the public and disaster risk reduction and management offices concerned are advised to take all necessary measures to protect life and property. Persons living in areas identified to be highly or very highly susceptible to these hazards are advised to follow evacuation and other instructions from local officials. For heavy rainfall warnings, thunderstorm/rainfall advisories, and other severe weather information specific to your area, please monitor products issued by your local PAGASA Regional Services Division.
