The intertropical convergence zone (ITCZ) may bring scattered rain showers over some parts of the country in the next 24 hours, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said on Wednesday afternoon, Oct. 20.
The ITCZ is a region where winds coming from the northern and southern hemispheres converge resulting in the formation of clouds and rainfall.
In the next 24 hours, cloudy skies with scattered rain showers and thunderstorms may prevail over Aurora, Cavite, Laguna, Batangas, Rizal, Quezon, Oriental Mindoro, Occidental Mindoro, Marinduque, Romblon, Palawan, Albay, Catanduanes, Camarines Norte, Camarines Sur, Sorsogon, Masbate, Aklan, Antique, Iloilo, Guimaras, and Negros Occidental.
PAGASA weather specialist Ariel Rojas advised the public to remain vigilant against possible flash floods or landslides during severe thunderstorms.
Meanwhile, the northeasterly surface wind flow may bring partly cloudy to cloudy skies with isolated light rains over Batanes and Babuyan Islands.
Metro Manila and the rest of the country may also experience partly cloudy to cloudy skies with isolated rain showers or thunderstorms.
Rojas noted that there is a slim chance of tropical cyclone formation inside or near the country's area of responsibility in the next two to three days.
However, he said that a low pressure area may develop by the weekend.
This weather disturbance will likely cross and bring rains over the central portion of the country, including Metro Manila.
