#WalangPasok: Class Suspensions For September 26, 2025, Friday

OPONG MAINTAINS ITS STRENGTH WHILE MOVING WESTWARD OVER THE PHILIPPINE SEA.

HAZARDS AFFECTING LAND AREAS

• Heavy Rainfall Outlook
• Refer to Weather Advisory No. 25 issued at 5:00 PM today for the heavy rainfall outlook due to Tropical Cyclone OPONG and the Southwest Monsoon.
• Severe Winds
• The wind signals warn the public of the general wind threat over an area due to the tropical cyclone. Local winds may be slightly stronger/enhanced in coastal and upland/mountainous areas exposed to winds. Winds are less strong in areas sheltered from the prevailing wind direction.
• Moderate to significant impacts from storm-force winds are possible within any of the areas under Wind Signal No 3.
• Minor to moderate impacts from gale-force winds are possible within any of the areas under Wind Signal No. 2.
• Minimal to minor impacts from strong winds are possible within any of the areas under Wind Signal No. 1.
• The highest Wind Signal that may be hoisted throughout the passage of OPONG is Wind Signal No. 4.
• The Southwest Monsoon enhanced OPONG, will bring strong to gale-force gusts over the following areas not under Wind Signal (especially in coastal and upland areas exposed to winds):
• Today: Ilocos Region, Cagayan Valley, Palawan, Visayas, Zamboanga del Norte, Misamis Occidental, Misamis Oriental, Camiguin, Caraga Region, and Davao Region.
• Tomorrow (26 September): Ilocos Region, Cordillera Administrative Region, Cagayan Valley, Palawan, Visayas, Zamboanga del Norte, Misamis Occidental, Misamis Oriental, Camiguin, Caraga Region, and Davao Region.
• Saturday (27 September): Luzon and Western Visayas.

HAZARDS AFFECTING COASTAL WATERS

• A Gale Warning is in effect over the eastern seaboard of Southern Luzon and Visayas. Refer to Gale Warning No. 2 issued at 5:00 PM today.
• 24-Hour Sea Condition Outlook
• Up to very rough, high, or very high over the following coastal waters:
• Up to 11.0 m: The seaboards of Catanduanes; the eastern seaboards of Albay and Sorsogon; the northern and eastern seaboards of Northern Samar and Eastern Samar.
• Up to 6.0 m: The northern and eastern seaboards of Camarines Norte and Camarines Sur.
• Up to 5.0 m: The seaboards of Quezon and Marinduque; the remaining seaboards of Bicol Region, Northern Samar, and Eastern Samar.
• Up to 4.5 m: The seaboards of Aurora, Batangas, Oriental Mindoro, Occidental Mindoro including Lubang Island, Romblon, Samar, and Biliran; the western seaboard of Zambales, Bataan, and Cavite; the northern seaboards of Aklan, Capiz, Iloilo, and Leyte.
• Sea travel is risky for all types or tonnage of vessels. All mariners must remain in port or, if underway, seek shelter or safe harbor as soon as possible until winds and waves subside.
• Up to rough seas over the following coastal waters:
• Up to 4.0 m: The seaboards of Isabela, Calamian Islands, Cuyo Islands, and Bucas Grande Island; the eastern seaboards of Dinagat and Siargao Islands.
• Up to 3.5 m: The eastern seaboards of Cagayan including Babuyan Islands, Pampanga, Bulacan, and Metro Manila; the remaining seaboards or Cavite, Dinagat Islands, and Siargao Island.
• Mariners of small seacrafts, including all types of motorbancas, are advised not to venture out to sea under these conditions, especially if inexperienced of operating ill-equipped vessels.
• Up to moderate seas over the following coastal waters:
• Up to 2.5 m: The seaboards of Surigao del Norte, Davao del Sur, and Davao Oriental; the remaining seaboards of Palawan and Visayas.
• Mariners of motorbancas and similarly-sized vessels are advised to take precautionary measures while venturing out to sea and, if possible, avoid navigation under these conditions.
• Coastal Inundation
• There is high risk of life-threatening storm surge with peak heights exceeding 3.0 m within 36 hours over the low-lying or exposed coastal localities of Metro Manila, Central Luzon, CALABARZON, Occidental Mindoro including Lubang Island, Oriental Mindoro, Marinduque, Romblon, Bicol Region, Northern Samar, Eastern Samar, Samar, Biliran, Leyte, and Cebu. Refer to Storm Surge Warning No. 5 issued at 2:00 PM today for the details.

TRACK AND INTENSITY OUTLOOK

• 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 the hoisted Wind Signals (for direct wind threat of the tropical cyclone) and “Other Hazards affecting Land Areas” for more details. Furthermore, the track may still shift more to the north or to the south but within the limit of the forecast confidence cone.
• OPONG is forecast to make landfall over Northern Samar or the northern portion of Eastern Samar tomorrow (26 September) early morning before heading towards Bicol Region, where it is likely to make another landfall in the vicinity of Sorsogon tomorrow morning. Throughout tomorrow, OPONG will move generally west northwestward near or over Sibuyan Sea and traverse the mainland and/or island provinces of Bicol Region, southern CALABARZON, and northern MIMAROPA, before emerging over the West Philippine Sea on Saturday (27 September) early morning.
• OPONG may reach typhoon category before making landfall. It will then weaken as it crosses the archipelago, although it will likely remain as a typhoon or severe tropical storm during the passage. Re-intensification is highly likely once OPONG emerges over the West Philippine Sea.
