September 24, 2025 — Residents across Mindanao are advised to brace for possible heavy rains and thunderstorms as Tropical Storm “Opong” (international name: Bualoi) continues to move closer to the Philippine landmass, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
