Scattered rains to prevail over Metro Manila, other parts of the Philippines
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said on Tuesday, Dec. 10 that three weather systems persist, which could bring cloudy and rainy conditions across Metro Manila and other parts of the country over the next 24 hours.
PAGASA said the shear line is expected to bring cloudy skies, scattered rains, and isolated thunderstorms across Metro Manila, Cavite, Laguna, Batangas, Rizal, Quezon, Bicol Region, Marinduque, Oriental Mindoro, Bulacan, and Aurora.
The shear line forms where the cold winds from the northeast monsoon (amihan) meet the warm winds from the Pacific Ocean (easterlies), resulting in rainfall.
PAGASA said the intertropical convergence zone (ITCZ) may also bring cloudy skies with scattered rains and thunderstorms over Zamboanga del Norte and Palawan.
The ITCZ is where the winds from the northern and southern hemispheres converge, leading to the formation of rain clouds. It is also a breeding ground for tropical cyclones.
Likewise, PAGASA said the amihan could bring cloudy skies and rains over Cagayan Valley, Apayao, Kalinga, Mountain Province, and Ifugao.
It warned that flash floods and landslides could occur in areas affected by the three weather systems, particularly during moderate to heavy rainfall.
Meanwhile, PAGASA said the amihan may have minimal impact on Ilocos Region, the rest of Cordillera Administrative Region, and the rest of Central Luzon, where only partly cloudy to cloudy skies with isolated light rains will occur.
The rest of the country will experience partly cloudy to cloudy skies with isolated rain showers due to localized thunderstorms.
The public is advised to remain vigilant for possible flash floods or landslides during severe thunderstorms.
