The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Monday, April 21 said the Intertropical Convergence Zone (ITCZ) and the easterlies will be the dominant weather systems that may affect the country.
Over the next 24 hours, the ITCZ, which forms when winds from the northern and southern hemispheres converge, will bring cloudy skies, scattered rains, and thunderstorms to Davao Region, Surigao del Sur, Sarangani, Sultan Kudarat, Basilan, Sulu, and Tawi-Tawi.
Residents in these areas are advised to remain alert for possible of flash floods or landslides, particularly during moderate to heavy rainfall.
While partly cloudy to cloudy skies are expected to prevail over the rest of Mindanao, PAGASA also warned residents to stay vigilant for possible flash floods or landslides that may occur during severe thunderstorms.
Meanwhile, the rest of the country will continue to experience generally partly cloudy to cloudy conditions, with chances of isolated rain showers or thunderstorms, particularly in the afternoon or evening, due to warm winds from the Pacific Ocean, known as the “easterlies.”
