The Philippine Space Agency (PhilSA) has generated flood extent maps for Regions I, CAR, II, III, IV-A, and IV-B following the heavy rains due to combined effects of Tropical Storm #CrisingPH, Severe Tropical Storm #BisingPH, and the southwest monsoon (habagat). The maps show the flood extent of said regions as of 18 July 2025, 5:45 AM (PhST). These areas were identified by Artificial Intelligence from a composite of three Sentinel-1A C band radar images acquired on 20 March 2025, 13 April 2025, and 18 April 2025. Please be advised that the accuracy of these maps is still subject to field validation. Floods, which may have subsided before this time period, will not be visible in the available imagery.
