MANILA -- Rains will continue to dampen most of Luzon and parts of the Visayas due to the southwest monsoon and a low pressure area (LPA), the weather bureau said Tuesday.
"Currently, the southwest monsoon or 'habagat' affects a huge part of central and southern Luzon. We expect that the rains brought by 'habagat' will continue over Metro Manila and nearby provinces until Wednesday," Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) forecaster Dan Villamil said in a public briefing.
He added that PAGASA expects the southwest monsoon to prevail over most parts of the country, particularly the western section, throughout the week.
PAGASA has been monitoring a cloud cluster, saying an LPA was spotted 715 km. east of Baler, Aurora.
The bureau's 4 p.m. bulletin, however, did not specify whether the LPA is likely to develop into a tropical cyclone.
PAGASA said scattered rain showers and thunderstorms would be experienced over Metro Manila, Central Luzon, Calabarzon, Bicol Region, Mimaropa, Western Visayas, and Samar provinces due to the southwest monsoon and the LPA.
Flash floods or landslides are possible in these areas due to moderate to at times heavy rains.
Villamil said light to moderate to at times heavy rains are forecast over Metro Manila, Bataan, Zambales, Batangas, Cavite, Occidental Mindoro, and northern Palawan, including Cuyo on Calamian Islands.
He said the rest of the country will experience isolated rain showers caused by localized thunderstorms.
Meanwhile, moderate to strong winds and moderate to rough seas will prevail over extreme northern Luzon.
