PAGASA warns: La Niña looms
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has raised a La Niña alert due to cooling sea surface temperatures in the central and eastern equatorial Pacific.
There is a 70% probability that La Niña will form between October and December 2025 and is expected to continue until February 2026.
La Niña is characterized by cooler-than-average waters in the region and is associated with an above-average number of tropical cyclones entering the Philippine Area of Responsibility (PAR).
The phenomenon can lead to more frequent rain-bearing weather systems, potentially causing floods and landslides in susceptible areas.
These rains could be brought about by weather systems such as monsoons, thunderstorms, low pressure areas (LPAs), easterlies, shearlines, and intertropical convergence zones.
PAGASA also reported an LPA bringing 50 to 100 millimeters of rainfall over Cagayan, Isabela, Quirino, and Aurora until Wednesday, September 17, with similar rainfall expected over Batanes, Cagayan, and Apayao by Thursday.
