Manila: Rains will continue to affect most parts of the country on Tuesday due to the influence of four prevailing weather systems, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said. As of 2 a.m., a low pressure area (LPA) was located about 725 kilometers southwest of Pag-asa Island in Kalayaan, Palawan, outside the Philippine Area of Responsibility (PAR). According to Philippines News Agency, PAGASA stated that the weather disturbance is unlikely to develop into a tropical cyclone within the next 24 hours. Despite this, the trough of the LPA is expected to bring scattered rains and thunderstorms over the Zamboanga Peninsula, Basilan, Tawi-Tawi, and Palawan. Scattered rains and isolated thunderstorms caused by a shear line will also affect the Bicol Region, Quezon, Oriental Mindoro, Marinduque, Romblon, and Northern Samar. Meanwhile, the easterlies will bring similar weather conditions to the rest of the Visayas. PAGASA warned that moderate to heavy rains in thes e areas may trigger flash floods or landslides. The northeast monsoon or "amihan" will cause light rains over the Cordillera Administrative Region, Cagayan Valley, and Aurora, while Metro Manila and the rest of Luzon may experience isolated light rains. In Mindanao, the easterlies will continue to bring isolated rainshowers or thunderstorms to the rest of the region. PAGASA also said moderate to strong winds and moderate to rough seas will prevail over Luzon and the eastern sections of the Visayas and Mindanao. Elsewhere, winds will be light to moderate, with slight to moderate coastal waters.
