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:
