Typhoon Bualoi, also known as Typhoon Opong in the Philippines, was a strong and deadly tropical cyclone that affected the central Philippines and northern Vietnam in late September 2025.
It originated near Yap on September 22, intensified into a typhoon, and made multiple landfalls in the Philippines before moving westward into the South China Sea. It later struck northern central Vietnam as a Category 2-equivalent typhoon.
This was the second tropical cyclone to be named Bualoi. The name, which was provided by Thailand, refers to a Thai dessert made of chewy rice balls and coconut milk. A previous Typhoon Bualoi occurred in 2019.

Key impacts include:

• In the Philippines, Bualoi caused at least 20 deaths, 13 missing persons, extensive damage to thousands of homes, schools, roads, bridges, and power infrastructure, affecting about 400,000 people evacuated.
• Agricultural and infrastructure damages were significant, especially in provinces like Masbate and Oriental Mindoro.
• In Vietnam, Bualoi made landfall with winds up to 130 km/h, resulting in at least 19 deaths, 88 injuries, and many missing persons.
• The storm caused flooding, landslides, power outages, and damage to over 100,000 homes, primarily in northern central regions such as Nghe An and Ha Tinh. It led to evacuations and disruptions including flight cancellations. Heavy rains continued after the typhoon, raising risks of further flooding and landslides.
• The storm was notable for its rapid intensification and multiple landfalls, leaving widespread destruction in its path across both countries.

Impact in Vietnam

As of September 30, 2025, Bualoi was considered the most devastating storm to hit Vietnam that year. 

• Casualties: The death toll in Vietnam rose to at least 19, with more than a dozen people missing.
• Damage and flooding: The storm unroofed and damaged over 100,000 houses, particularly in the Nghe An and Ha Tinh provinces. Torrential rains led to widespread flooding in cities, including Hanoi, and landslides in northern and central provinces.
• Disruptions: In preparation for the storm, over 28,500 people were evacuated, and flights were delayed or cancelled at airports in central provinces. 

Impact in the Philippines

Before striking Vietnam, Typhoon Bualoi hit the central Philippines. 

• Casualties: The storm was responsible for at least 27 deaths in the Philippines.
• Evacuations: More than 400,000 people were evacuated in the Philippines.
• Timing: Bualoi struck the Philippines only days after Super Typhoon Ragasa had also caused significant damage and killed at least 14 people. 

Wider regional impact
As the storm weakened and moved inland, heavy rains continued to affect the region. 
Thailand and Laos: Flooding was reported in 17 provinces in Thailand, with some casualties. The weakened storm eventually crossed into Laos.
