Forecast rainfall may be higher in mountainous and elevated areas. Moreover, impacts in some areas may be worsened by significant antecedent rainfall.
The public disaster risk reduction and management offices concerned are advised to take all necessary measures to protect life and property. PAGASA Regional Services Divisions may issue Heavy Rainfall Warnings/Thunderstorm Advisories, and other severe weather information specific to their areas of responsibility as appropriate.
Unless significant changes occur, the next Weather Advisory will be issued at 5:00 AM tomorrow.
For Additional Information: The key difference between a Heavy Rainfall Warning and a Weather Advisory lies in their forecast period, coverage areas, and accuracy. A Heavy Rainfall Warning provides forecasts for the next three hours and applies up to the municipal level. It is more precise as it utilizes Doppler radar technology to track real-time rainfall intensity, making it highly effective for immediate decision-making in flood-prone areas. A Weather Advisory, on the other hand, covers a 24-hour period but is issued only at the provincial level. It provides a broader outlook on potential weather disturbances but lacks the short-term accuracy of Heavy Rainfall Warnings. For class suspensions or other official decisions, please refer to Heavy Rainfall Warnings issued by the respective PAGASA Regional Services Divisions.
