The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Wednesday, July 10, said two rain-bearing weather systems are expected to affect most parts of the country in the next 24 hours.
PAGASA Weather Specialist Obet Badrina said the intertropical convergence zone (ITCZ), where winds from the northern and southern hemispheres converge—and the easterlies, or warm winds originating from the Pacific Ocean, will be the prevailing weather systems.
Metro Manila, Cavite, Laguna, Batangas, Rizal, Quezon, Oriental Mindoro, Occidental Mindoro, Marinduque, Romblon, Palawan, Bicol Region, and Western Visayas will experience cloudy weather conditions with scattered rain showers and thunderstorms due to the ITCZ.
Central Luzon may also experience cloudy weather with scattered rain showers and thunderstorms caused by the easterly winds.
Residents have been warned of potential flash floods or landslides due to occasionally moderate to heavy rains and thunderstorms from the ITCZ and easterlies.
Meanwhile, the ITCZ may cause partly cloudy to cloudy weather with isolated rain showers or thunderstorms across the rest of Visayas and Mindanao.
The rest of Luzon may also experience partly cloudy to cloudy skies with isolated rain showers due to localized thunderstorms.
PAGASA also warned the public about severe thunderstorms that could lead to flash floods or landslides.
Badrina said that, as of Wednesday, PAGASA has not monitored any tropical cyclones or low pressure areas near or within the country’s area of responsibility, but is monitoring a cluster of clouds for potential development into a weather disturbance.
