MANILA – The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) announced that three weather systems, including the southwest monsoon (habagat), will bring widespread rains across the country.

As of 4 a.m., a low-pressure area (LPA) was located 375 kilometers east-northeast of Casiguran, Aurora, or 400 km east of Tuguegarao City, Cagayan.

This LPA is expected to develop into a tropical cyclone within the day, causing cloudy skies, scattered rains, and thunderstorms in the Ilocos Region, Cordillera Administrative Region, Cagayan Valley, and Aurora.

Meanwhile, PAGASA is also monitoring Tropical Storm “Pulasan,” which remains outside the Philippine Area of Responsibility (PAR). Located 2,205 km east of southeastern Luzon, Pulasan has maximum sustained winds of 65 km/h and gusts up to 80 km/h.

Although Pulasan is unlikely to enter PAR, it will enhance the southwest monsoon, bringing more rain.

Monsoon rains are forecast for the northern portion of Palawan, Occidental Mindoro, Antique, and Negros Occidental. Other areas in Mimaropa, Western Visayas, and the Negros Island Region will also experience occasional rains due to the habagat.

Metro Manila, Zamboanga Peninsula, BARMM, Soccsksargen, Caraga, Northern Mindanao, and other parts of Luzon and Visayas can expect scattered rains and thunderstorms. The rest of Mindanao will see partly cloudy to cloudy skies with isolated rain showers.

PAGASA cautions against possible flash floods and landslides due to moderate to heavy rains. Rough coastal waters are expected in Visayas, Southern Luzon, and parts of Mindanao, while other regions will experience moderate to rough seas.
