The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has issued an updated afternoon weather forecast for May 23, 2025, warning of heavy rainfall across several regions in the country due to the presence of the Intertropical Convergence Zone (ITCZ).
From today until tomorrow afternoon, May 24, rainfall ranging from 50 to 100 mm is expected in numerous areas across Mindanao, including Zamboanga del Norte, Zamboanga del Sur, Zamboanga Sibugay, Misamis Occidental, Lanao del Norte, Lanao del Sur, Maguindanao del Norte, Maguindanao del Sur, Basilan, Sulu, Tawi-Tawi, Cotabato, South Cotabato, Sultan Kudarat, Sarangani, Davao del Norte, Davao del Sur, Davao de Oro, Davao Oriental, Agusan del Sur, Surigao del Sur, and Davao Occidental.
Rainfall will persist from tomorrow afternoon until Sunday afternoon (May 25) in Palawan and the same western and southern Mindanao provinces. By Sunday afternoon until Monday afternoon (May 26), moderate to heavy rains are forecasted over Palawan, Misamis Oriental, Bukidnon, and Lanao del Sur.
PAGASA emphasized that rainfall amounts could be higher in mountainous and elevated areas. Flooding and landslides may be aggravated by prior rainfall over the past few days. Local Disaster Risk Reduction and Management Councils are advised to remain alert and ensure the safety of residents in vulnerable areas.
General Flood Advisories (GFAs) have also been issued for multiple regions as of 6 PM today, including MIMAROPA (Region 4B), Zamboanga Peninsula (Region 9), Northern Mindanao (Region 10), Davao Region (Region 11), SOCCSKSARGEN (Region 12), CARAGA (Region 13), and BARMM.
As of the latest update, PAGASA confirms no active tropical cyclones or tropical cyclone-like vortexes (TCLVs) inside the Philippine Area of Responsibility (PAR). While there is a low chance for TCLV1 to develop into a tropical cyclone within the first week of the forecast period, it is not currently seen as a threat.
PAGASA clarifies that Heavy Rainfall Warnings are short-term, localized forecasts (valid for three hours) and more accurate, while Weather Advisories cover broader areas over 24 hours.
