The trough or extension of a low-pressure area (LPA) will bring rain over the Eastern and Central Visayas; and over the Caraga, Davao, and Northern Mindanao Regions, PAGASA said in its Monday 4 p.m. forecast.
Cloudy skies with rain, meanwhile, would prevail over the Cagayan Valley, Aurora, Quezon, and Bicol Region due to the Amihan.
The Amihan will also bring partly cloudy to cloudy skies with light rain over Metro Manila and the rest of Luzon, PAGASA added.
Localized thunderstorms and the trough of the LPA will bring partly cloudy to cloudy skies with isolated rain showers or thunderstorms over the rest of the country.
The weather bureau warned of possible flash floods and landslides in areas affected by rainfall.
Winds across the country would be moderate to strong with moderate to rough coastal conditions.
The sun will rise over Metro Manila on Tuesday at 6:22 a.m. — DVM, GMA Integrated News
