➣ 24-Hour Sea Condition Outlook
Up to very rough seas over the following coastal waters:
• Up to 4.5 m: The northern seaboard of Batanes.
• 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 Babuyan Islands, Ilocos Sur, La Union, and Pangasinan; the northeastern seaboard of mainland Cagayan; the remaining seaboard of Batanes.
• Up to 3.0 m: The seaboards of Ilocos Norte, Isabela, and northeastern Aurora; the northern seaboard of Camarines Norte and Camarines Sur; the northern and eastern seaboards of Catanduanes and Northern Samar; the eastern seaboard of Davao Oriental; the remaining seaboard of mainland Cagayan.
• 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 Zambales, Lubang Islands, and Surigao del Sur; the western seaboards of Bataan, Cavite, Batangas, Occidental Mindoro, Calamian Islands, northern mainland Palawan, and Kalayaan Islands; the northern and eastern seaboards of Polillo Islands; the eastern seaboards of Albay, Sorsogon, Eastern Samar, Dinagat Islands, and Siargao-Bucas Grande Islands; the remaining seaboards of Aurora and Camarines Norte.

TRACK AND INTENSITY OUTLOOK
• It must be emphasized that heavy rainfall and severe winds 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.
• On the latest forecast track, MAYMAY will traverse the mountainous terrain of Northern Luzon before emerging over the eastern coastal waters of Isabela or Cagayan.
• MAYMAY is forecast to continue weakening while moving further inland and may be downgraded into a remnant low this afternoon or evening. However, due to interaction with the rugged terrain, an earlier weakening is possible. The remnant low of MAYMAY will move generally southeastward until it merges into the larger circulation of Tropical Cyclone DOLPHIN.
