The tail-end of a frontal system is expected to bring cloudy skies with scattered to widespread rains and thunderstorms over the Bicol region and Kalayaan Islands, PAGASA said on Thursday.
In its 24-hour forecast, the weather agency warned affected residents of possible flash floods or landslides due to moderate to heavy rains.
PAGASA said the frontal system may also bring cloudy skies with scattered rainshowers and thunderstorms over CALABARZON, Western Visayas, Eastern Visayas, and the rest of MIMAROPA.
Flash floods and landslides are also possible.
Meanwhile, cloudy skies with rains are expected to prevail over the Cagayan Valley, Cordillera Administrative Region, and Aurora due to the northeast monsoon, which may cause flash floods or landslides.
It may also bring partly cloudy to cloudy skies with isolated light rains over Metro Manila, the Ilocos Region, and the rest of Central Luzon.
Mindanao and the Central Visayas may, meanwhile, experience partly cloudy to cloudy skies with isolated rainshowers due to localized thunderstorms.
PAGASA said severe thunderstorms may cause flooding and landslides.
