MANILA, Philippines — Most of the country will still experience cloudy skies and rain on Saturday as the effects of the northeast monsoon, shear line, and intertropical convergence zone (ITCZ) persist, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) said.
In an early morning weathercast. Pagasa specialist Benison Estareja said the cold winds of the northeast monsoon, locally termed amihan, are forecast to bring rain to Northern and Central Luzon, particularly Cagayan Valley, Cordillera Administrative Region, and Aurora province.
He likewise said that Metro Manila, Ilocos Region, and the rest of Central Luzon could expect cloudy weather with isolated rain showers on Saturday.
The shear line, meanwhile, is predicted to cause heavy rains in Quezon, Laguna, Rizal, and most of the Bicol Region.

In Palawan and for most of Visayas and Mindana, the ITCZ will mainly influence their atmospheric conditions on Saturday.

He likewise said it would be rainiest in the eastern portion of Visayas and the Caraga Region, and that up to 200 millimeters of rain may be expected in Northern Samar and Eastern Samar.
Estareja added that moderate to heavy rain fall of up to 100 millimeters is forecast to occur in Eastern Visayas, Surigao del Norte, and Dinagat Islands on Saturday.

Estareja continued, “Base naman sa ating latest satellite animation, maraming mga may kumpol ng ulap gaya ng dito sa kaliwa at kanang bahagi ng ating bansa, pero wala sa mga ito ay magiging bagyo sa mga unang araw ng Disyembre.”
(Based on our latest satellite animation, there are many clusters of clouds such as these on the left and right parts of the country, but none of these would become a tropical cyclone in the first days of December.)
As for the country’s seaboards, Pagasa raised a gale warning over the easter coasts of Luzon, particularly Isabela, northern Aurora and part of the Polillo Islands due to the northeast monsoon.
Pagasa said these seaboards will have waves between 2.8 meters and 4.5 meters on Saturday.
“{By Sunday], it is possible that the gale warning for the eastern seaboard of Luzon will be lifted, but it will remain wavy for most of Luzon and gentle to moderate in Visayas and Mindanao,” Estareja said.
