Typhoon Agnes, known in the Philippines as Typhoon Undang, was the fourth and final tropical cyclone to affect the Philippines during the 1984 Pacific typhoon season. An area of disturbed weather developed near the equator and the Caroline Islands on October 28. Following an increase in organization, the cyclone was designated a tropical storm on October 31. After tracking northwest initially, Agnes turned west-northwest the next day, a course that the system would maintain for the rest of its lifetime. Agnes intensified into a typhoon on November 2, and on November 4, attained peak intensity. The storm then made landfall on Samar Island, part of the Philippines, at that intensity. The storm weakened over land, but re-intensified over the South China Sea; Agnes obtained a secondary peak intensity on November 6. The next day, Typhoon Agnes moved ashore Vietnam while still at typhoon intensity. The storm rapidly deteriorated over land and dissipated by November 8 over Thailand.
Typhoon Agnes was the final of a series of tropical cyclones to affect the Philippines that season, following June, Ike, and Warren. Agnes brought widespread damage to several provinces across the central section of the archipelago. In the Iloilo province, 230 people were killed and four others were injured. Provincewide, a total of 21 homes were flattened, resulting in 1,326 homeless people. Damage in the province amounted to at least $5 million. Approximately 20% of the rice crop was destroyed in Iloil
Why this event still matters
Historical incidents shape the rules that protect people today — building codes, evacuation policy, warning systems and inspection regimes almost always trace back to a specific disaster. Studying Typhoon Agnes alongside current events is how preparedness improves.
