The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) announced that easterlies will dominate most of the country on Saturday, April 12.
In its weather forecast, PAGASA said that easterlies—or winds coming from the Pacific Ocean—will prevail over most parts of the country.
PAGASA added that these easterlies may bring cloudy skies with scattered rains and thunderstorms to the Zamboanga Peninsula, Basilan, Sulu, and Tawi-Tawi.
Likewise, it noted that partly cloudy to cloudy skies with isolated rain showers or thunderstorms may also be expected in Metro Manila and the rest of the country.
PAGASA warned of possible flash floods or landslides due to moderate to occasionally heavy rains, especially during severe thunderstorms.
