With the onset of the wet season southwest monsoon or habagat will continue to bring in rain in large parts of the country for the rest of the week, or until Sunday.
The Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) said light to moderate rains will dampen parts of the country.
PAGASA officially declared the rainy season had started Friday after the required amount of rainfall was met.
Associated with thunderstorms, the habagat will only slightly weaken on Saturday, but will continue to dump light to moderate rains, said PAGASA meteorologist Ezra Bulquerin.
Occasional heavy monsoon rains on Wednesday may trigger floods and landslides in Metro Manila, Ilocos and Cordillera regions, the Babuyan islands, and the provinces of Cavite, Batangas, Bataan and Zambales, said PAGASA.
Mimaropa and the rest of Cagayan Valley, Central Luzon and Calabarzon, meanwhile, will experience light to moderate rains due to the habagat while localized thunderstorms may affect Bicol region, Visayas and Mindanao.
Typhoon Domeng had enhanced the southwest monsoon over the weekend, triggering heavy rains and floods in large swaths of Luzon and Visayas.
