• Up to 4.5 m: The northern seaboards of mainland Cagayan and Ilocos 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.
• KIYAPO will continue moving west northwestward until tomorrow (25 July) towards the Luzon Strait before turning northwestward to northward for the remaining forecast period. On the forecast track, the center of KIYAPO may pass close to the northeastern portion of mainland Cagayan between this morning and afternoon, then pass very close or make landfall in the vicinity of Babuyan Islands between this afternoon and evening. It is forecast to exit the Philippine Area of Responsibility (PAR) by tomorrow morning.
• KIYAPO will continue to intensify while traversing Extreme Northern Luzon and may be upgraded into a severe tropical storm after passing the Babuyan Islands. While moving over the West Philippine Sea, it may undergo rapid intensification and reach typhoon category before making landfall over southern mainland China. Afterwards, KIYAPO is expected to weaken as it moves inland and interacts with the surrounding terrain of mainland 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.
The next tropical cyclone bulletin will be issued at 11:00 AM today.
