MANILA – Today, Tuesday, January 21, 2025, three weather systems are expected to bring rainfall to various parts of the Philippines.

The easterlies, shear line, and northeast monsoon, also known as the “amihan,” will impact different regions of the country.

The shear line will bring scattered rains and isolated thunderstorms to Northern and Eastern Samar. Meanwhile, the easterlies will cause scattered rain showers over the Dinagat Islands, Surigao del Norte, and Surigao del Sur.

PAGASA (Philippine Atmospheric, Geophysical and Astronomical Services Administration) has warned that moderate to heavy rainfall in these areas could potentially lead to flash floods or landslides.

The northeast monsoon will bring light rains to Cagayan Valley, Aurora, and Quezon, with isolated light rains expected over the rest of Luzon. The rest of the country will experience isolated rain showers or thunderstorms due to the easterlies, with the possibility of flash floods or landslides in areas experiencing severe thunderstorms.

Additionally, moderate to strong winds are forecasted over northern and central Luzon, along with moderate to rough coastal waters. Light to moderate winds and slight to moderate seas are expected over the rest of the country.

PAGASA also noted that no low-pressure area has been observed, and there is no potential tropical cyclone formation at this time.
