Typhoon Bualoi

Typhoon Bualoi, known in the Philippines as Typhoon Opong and in Vietnam as Typhoon No. 10 of 2025 (Vietnamese: Bão số 10 năm 2025), was a strong and devastating tropical cyclone that caused significant damage and loss of life across the central Philippines, particularly the regions of Bicol and Eastern Visayas, as well as Northern and Northern Central Vietnam, particularly Nghệ An and Hà Tĩnh in late September 2025. The twentieth named storm and the seventh typhoon of the 2025 Pacific typhoon season, Bualoi originated from a disturbance north of Yap on September 22. The disturbance gradually organized into a tropical depression and was assigned the name Opong by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA). On September 23, the system was designated 26W by the Joint Typhoon Warning Center (JTWC) and named Bualoi by the Japan Meteorological Agency (JMA). It strengthened into a tropical storm on September 24 and was later upgraded to a severe tropical storm as it moved west-southwest. Bualoi subsequently made six landfalls across Eastern Visayas and Mimaropa before reemerging through the Mindoro Strait, where it intensified into a Category 1-equivalent typhoon according to the JTWC. Bualoi gained more strength, reaching its peak intensity as a Category 2-equivalent typhoon before it made a final landfall over Hà Tĩnh on September 29. It later moved inland over Laos, where it rapidly weakened into a remnant low before it was reportedly dissipated on the following day.

Bualoi caused extensive damage in parts of the Philippines and Vietnam, leaving at least 94 people dead, 214 injured, and 23 others missing.
