Typhoon Bualoi, the 20th named storm of the 2025 Pacific season, struck Vietnam causing 36 deaths and damage to over 210,000 houses, with about 51.2K hectares of crops affected. The Category 2-equivalent tropical cyclone was known as 'Opong' in the Philippines and 'Bualoi' in the Japanese naming system.

The disaster highlighted the growing vulnerability of Southeast Asian nations to intensifying tropical cyclones linked to climate change. The Government of Viet Nam led life-saving response, search-and-rescue and restoration of essential services. The event is significant for understanding monsoon and cyclone patterns in the Asia-Pacific region.
