MANILA, Philippines — The intertropical convergence zone (ITCZ) is forecast to continue to bring rain showers to Mindanao on Friday, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) said.
In a 5 a.m. update, Pagasa weather specialist Grace Castañeda reported that heavy rains may occur in most parts of Mindanao, especially in the Zamboanga Peninsula, Bangsamoro Autonomous Region in Muslim Mindanao, Soccsksargen (South Cotabato, Cotabato, Sultan Kudarat, Sarangani, and General Santos City), and Davao Region due to the ITCZ, or “the line where winds from the northern and southern hemispheres meet.”
“Based on our latest analysis, this series of rainfall would continue over the next few days. So we advise our countrymen here in the Mindanao area to be more cautious as there is still a threat of flooding or landslides,” Castañeda said in Filipino.

Meanwhile, Castañeda said the ridge of a high-pressure area is forecast to persist in parts of extreme northern Luzon. She added that the HPA’s ridge would cause clear weather conditions in areas of Batanes and the Babuyan Islands.
Pagasa recently explained that the HPA causes higher maximum temperatures, thus diminishing the possibility of rainfall.

Easterlies, or the warm winds from the Pacific Ocean, are forecast to bring partly cloudy to cloudy skies in Metro Manila and the rest of Luzon, Castañeda said, noting that the areas would experience hot or fair weather conditions from morning to noon, while isolated rain showers or thunderstorms may occur in the evening.
Fair weather conditions are also expected in Palawan and the rest of the Visayas, brought about by easterlies, but there are still possible occasional rains and thunderstorms that may cause flooding or landslides.
No typhoons or low-pressure areas within or outside the Philippine area of responsibility are currently being monitored, Castañeda said. /das
