๐จ๐ซ ๐๐๐๐ข๐ญ๐ข๐จ๐ง๐๐ฅ ๐๐ง๐๐จ๐ซ๐ฆ๐๐ญ๐ข๐จ๐ง: The key difference between a ๐๐๐๐ฏ๐ฒ ๐๐๐ข๐ง๐๐๐ฅ๐ฅ ๐๐๐ซ๐ง๐ข๐ง๐ and a ๐๐๐๐ญ๐ก๐๐ซ ๐๐๐ฏ๐ข๐ฌ๐จ๐ซ๐ฒ lies in their forecast period, coverage areas, and accuracy. A ๐๐๐๐ฏ๐ฒ ๐๐๐ข๐ง๐๐๐ฅ๐ฅ ๐๐๐ซ๐ง๐ข๐ง๐ 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 ๐๐๐๐ญ๐ก๐๐ซ ๐๐๐ฏ๐ข๐ฌ๐จ๐ซ๐ฒ, 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 ๐๐๐๐ฏ๐ฒ ๐๐๐ข๐ง๐๐๐ฅ๐ฅ ๐๐๐ซ๐ง๐ข๐ง๐ ๐ฌ. For class suspensions or other official decisions, please refer to ๐๐๐๐ฏ๐ฒ ๐๐๐ข๐ง๐๐๐ฅ๐ฅ ๐๐๐ซ๐ง๐ข๐ง๐ ๐ฌ issued by the respective PAGASA Regional Services Divisions.
