A "weak" northeast monsoon, locally known as "amihan," may remain the dominant weather system in Northern Luzon, while the easterlies, which bring warm winds from the Pacific Ocean, may prevail throughout the rest of the country this weekend, said the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Friday, March 1.

In the next three days, the amihan is expected to bring cloudy skies and light rains to Cagayan Valley and Aurora, as well as isolated light rains to the rest of Northern and Central Luzon, based on the PAGASA's weekly weather outlook.

Meanwhile, the easterlies could bring Metro Manila and the rest of the country partly to mostly cloudy weather with isolated rain showers or thunderstorms.

From Monday to Wednesday, March 4 to 6, PAGASA said the easterlies will be the dominant weather system across the country as the amihan weakens, bringing partly cloudy to cloudy skies with chances of isolated rain showers or thunderstorms, mostly over the eastern section of the archipelago.

Another surge of amihan is expected to affect Northern and Central Luzon from Thursday to Friday, March 7 to 8, causing cloudy skies and light rains in Cagayan Valley, Aurora, and northern Quezon province.

Meanwhile, Metro Manila and the rest of Luzon may experience partly cloudy to cloudy weather, with isolated light rains.

PAGASA said Visayas and Mindanao may continue to have partly cloudy to cloudy skies with isolated rain showers or thunderstorms, mostly in the afternoon or evening, due to easterlies.

Weather specialist Benison Estareja said the amihan may gradually weaken until the “termination” of the northeast monsoon season in the “first half of March.”

In 2023, the end of the amihan season and beginning of the dry and warm season was declared on March 21.

Last week, PAGASA-Climate and Agrometeorology Division Assistant Weather Services Chief Ana Liza Solis said the termination of the northeast monsoon season may occur earlier than last year because of El Niño.
