MANILA, Philippines — The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (Pagasa) said on Saturday that an inter-tropical convergence zone (ITCZ) was affecting the Visayas and Mindanao.

By definition, the ITCZ is a convergence of winds in both northern and southern hemispheres.

According to the state weather bureau's early morning forecast, the Zamboanga Peninsula, SOCCSKSARGEN, the Bangsamoro Autonomous Region in Muslim Mindanao, Davao Occidental, and even Palawan are forecast to have cloudy skies with scattered rains and thunderstorms as a result of the ITCZ, while the rest of Mindanao and the Visayas will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms.

Pagasa also issued flood warnings in Zamboanga Peninsula, Davao and SOCCSKSARGEN and BARMM because of the ITCZ.

Meanwhile, Cagayan Valley, Aurora, Quezon, and Bicol Region will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms because of the easterlies, or warm winds blowing from the Pacific Ocean.

Metro Manila and the rest of Luzon will also have partly cloudy to cloudy skies with isolated rain showers or localized thunderstorms.

On Friday night, the weather bureau was monitoring a low pressure area that was 1,515 kilometers east of Central Luzon and also warned the public that a tropical cyclone threat was possible in the next two weeks.
