Apayao-Abulug river basin gets its own flood forecasting and warning system
4 November 2026
DOST-PAGASA put the Apayao-Abulug River Basin Flood Forecasting and Warning System into operation on 4 November 2026. The Apayao-Abulug is the ninth largest river basin in the Philippines and covers about 3,776 square kilometres. The river rises in the Apayao highlands of the Cordillera Administrative Region, crosses into Cagayan and empties into the Babuyan Channel at Abulug. The system runs on 13 automatic rainfall and water level gauging stations feeding an integrated monitoring facility. A new river centre studies the data and issues flood advisories for Apayao and Cagayan. DOST Secretary Renato U. Solidum Jr. said the launch supports the Early Warnings for All initiative of the United Nations and the World Meteorological Organization.
