The intertropical convergence zone (ITCZ), which is a region where the trade winds from the northern and southern hemispheres converge, remains the dominant weather system in the country, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said on Wednesday, Sept. 1.
Weather specialist Benison Estareja said the country is going through a "monsoon break" as the effect of the southwest monsoon, locally called "habagat," has temporarily weakened.
PAGASA defines monsoon break as the dry period that follows a rain event that may last for several days to two weeks.
In the next 24 hours, the ITCZ will continue to affect the country and will bring cloudy skies with scattered rain showers and thunderstorms over Metro Manila, Cavite, Laguna, Batangas, Rizal, Quezon, Oriental Mindoro, Occidental Mindoro, Marinduque, Romblon, Palawan, Aurora, Bicol, Western Visayas, and Central Visayas.
Meanwhile, the rest of the country will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms.
PAGASA warned the public against flash floods or landslides that may occur during severe thunderstorms, which are often associated with short-lived heavy rain, lightning, thunder, gusty winds, and sometimes hail.
Estareja said PAGASA has not monitored a weather disturbance that may develop in the next two days.
