24-Hour Sea Condition Outlook
Note: These are forecast sea condition over the coastal waters and not related to storm surge heights or inundation.
Up to very rough over the following coastal waters:
• Up to 5.0 m: The seaboards of Batanes
• Up to 4.5 m: The seaboards of Ilocos Sur and Isabela; the eastern seaboard of Mainland Cagayan; the western seaboard of Ilocos Norte
• 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, La Union, Pangasinan, and northern Aurora; the remaining seaboard of mainland Cagayan
• Up to 3.5 m: The remaining seaboard of Aurora
• Up to 3.0 m: The seaboard of northern Quezon; the northern and eastern seaboard of Polillo Islands

TRACK AND INTENSITY OUTLOOK
• Over the West Philippine Sea, PEPITO will continue moving generally west northwestward today until it exits the PAR region this morning or noon. Outside the PAR region, the tropical cyclone will turn more westward or west southwestward on Tuesday (19 November) under the influence of an incoming northeasterly wind surge.
• Further weakening will also occur as PEPITO moves over the West Philippine Sea due to the same surge creating unfavorable environment.
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.
The next tropical cyclone bulletin will be issued at 5:00 AM today.
