Typhoon Ragasa

Typhoon Ragasa, known in the Philippines as Super Typhoon Nando, was an extremely powerful, large, and destructive tropical cyclone that severely affected the northernmost portions of Luzon island in the Philippines and Hualien County in Taiwan, and impacted Hong Kong, Macau, South China and Vietnam in late September 2025. It is also the second-strongest tropical cyclone worldwide in 2025, behind Hurricane Melissa in the Atlantic. Ragasa is the eighteenth named storm, fifth typhoon, and both the only violent typhoon and Category 5-equivalent super typhoon of the 2025 Pacific typhoon season.

Ragasa originated from an area of convection north of Yap that developed into a tropical depression on September 17. Moderate wind shear initially limited organization, but the system was upgraded to a tropical storm the following day and assigned the name Ragasa by the Japan Meteorological Agency (JMA). It gradually intensified over the next two days, becoming a typhoon on September 19.
