MANILA – Rains will spread across most of the Philippines today, Monday (16 Dec 2024), driven by three weather systems, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

The shearline over southern Luzon will bring scattered rains and thunderstorms to Quezon, Marinduque, Oriental Mindoro, and the Bicol region.

The intertropical convergence zone (ITCZ) will cause similar weather across Eastern and Central Visayas, Northern Mindanao, Soccsksargen, Caraga, and Davao Region.

Meanwhile, the northeast monsoon, or “amihan,” will bring rains to Cagayan Valley, the Cordillera Administrative Region, and Aurora.

PAGASA warns that moderate to heavy rains in these areas could trigger flash floods or landslides.

Other parts of Mindanao and Luzon will see isolated rain showers due to the ITCZ and northeast monsoon. The rest of the Visayas will experience localized thunderstorms.

Additionally, strong winds and rough seas are expected in Northern and Central Luzon, while moderate to strong winds and rough coastal conditions are forecast across the rest of Luzon, as well as the eastern Visayas and Mindanao.

Elsewhere, light to moderate winds and slight to moderate seas are anticipated.

PAGASA also confirmed that no low-pressure areas are being monitored for potential tropical cyclone development.
