• Up to 5.0 m: The seaboards of Batanes
• Up to 4.5 m: The western seaboard of Ilocos Norte; the seaboards of Ilocos Sur and Isabela; the eastern seaboard of mainland Cagayan

Up to rough seas over the following coastal waters:
• Up to 4.0 m: The seaboards of Babuyan Islands; the remaining seaboard of mainland Cagayan

TRACK AND INTENSITY OUTLOOK
• PEPITO will continue moving northwestward to west northwestward today over the West Philippine Sea until it exits the PAR region this morning or noon. Outside the PAR region, the tropical cyclone will turn more westward or west southwestward tomorrow (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. This tropical cyclone may become a remnant low by Wednesday (20 November) late evening or Thursday (21 November) early morning over the coast of southern China.
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.
