The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has advised the public to brace for more rains brought by the southwest monsoon, locally known as the “habagat,” as it monitors a Low-Pressure Area (LPA) outside the Philippine Area of Responsibility (PAR).

As of 3 a.m., Friday, June 27, the LPA was located 1,685 kilometers east of southeastern Luzon.

PAGASA weather specialist Benison Estareja said the weather system is not expected to develop into a tropical depression until Saturday, June 28, but two possible scenarios are being considered.

He explained that the LPA may slowly move and enter the PAR over the weekend, or a new LPA could form east of Luzon within the PAR and absorb or replace the existing weather system.

In either scenario, the LPA is likely to enhance the habagat, which will bring scattered rains and thunderstorms from Saturday through Tuesday, July 1.

Affected areas include Metro Manila, Central and Southern Luzon, Visayas, and northern and western Mindanao.

While rainfall may not be continuous, Estareja noted that daily rain showers, sometimes heavy, are expected.

He urged residents in these areas to prepare by bringing umbrellas and coordinating with local government units, as persistent rains could cause flooding in low-lying communities, river overflows, and landslides in mountainous regions.
