Other Hazards Affecting Land Areas

Heavy Rainfall

Heavy rainfall is expected as Opong and the Southwest Monsoon continue to affect the country. Flooding and landslides are possible in high-risk areas.

Severe Winds

• Signal No. 3: Moderate to significant impacts possible
• Signal No. 2: Minor to moderate impacts possible
• Signal No. 1: Minimal to minor impacts possible

The highest signal that may be raised during the passage of Opong is Signal No. 4.

The Southwest Monsoon enhanced by Opong will bring strong to gale-force gusts over many areas of Luzon, Visayas, and Mindanao.

Coastal Waters

Very rough to high seas are expected:

• Up to 11.0 m: Catanduanes; eastern seaboards of Albay and Sorsogon; northern and eastern seaboards of Northern Samar and Eastern Samar
• Up to 6.0 m: Northern and eastern seaboards of Camarines Norte and Camarines Sur
• Up to 5.0 m: Quezon, Marinduque, Romblon, and remaining Bicol seaboards

Rough seas also affect other areas including Isabela, Aurora, Batangas, Mindoro, Samar, Biliran, northern Leyte, and Dinagat Islands. Sea travel is risky for small seacrafts.

• Opong is moving west northwestward toward Eastern Visayas–Southern Luzon. It may make landfall over Northern Samar early morning of September 26, then cross Bicol Region during the day before traversing Southern Luzon until early September 27.
• Opong may reach typhoon category before landfall, weaken slightly as it crosses land, and then re-intensify over the West Philippine Sea.
• Exit from PAR is expected by late September 27.
