On the other hand, the ridge of a high-pressure area (HPA) extended across Luzon as of Wednesday, meaning there would be generally fair weather except for isolated rains, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) said.
In its outlook for Thursday, Pagasa said Caraga and Davao regions would have cloudy skies with light to moderate rain showers and thunderstorms due to the trough, or extension, of an LPA approaching Mindanao.
Due to the ridge of an HPA, which typically brings clear skies, the weather in Metro Manila and the rest of the country will be generally fair but partly cloudy with isolated rain showers or thunderstorms, according to the Pagasa.
Light to moderate winds blowing from the east to southeast will prevail over Luzon and Visayas and coming from the east to northeast over Mindanao. The coastal waters throughout the archipelago would be slight to moderate, it added.
