Rains may affect some parts of the Philippines in the next 24 hours due to three weather systems prevailing across the archipelago on Wednesday morning, March 24.
Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) weather specialist Benison Estareja said light rains due to the northeast monsoon or "amihan" may affect Aurora, Quezon, Batanes, Cagayan, Isabela, Quirino, Nueva Vizcaya, Abra, Apayao, Benguet, Ifugao, Kalinga, and Mountain Province.
Estareja said this could be the final wave of the annual northeast monsoon season in the country this year.
Meanwhile, warm and humid weather condition due to the easterlies may be felt in Southern Luzon, Visayas, and Mindanao, he said.
Cloudy skies with scattered rain showers and thunderstorms may affect Agusan del Norte, Agusan del Sur, Dinagat Islands, Surigao del Norte, Surigao del Sur, Davao de Oro, Davao del Norte, Davao del Sur, Davao Oriental, Davao Occidental, Biliran, Leyte, Northern Samar, Samar, Eastern Samar, Southern Leyte, Cebu, Bohol, Negros Oriental, and Siquijor.
The tail-end of frontal system or shearline, which is the boundary between amihan and easterlies, may also bring scattered rain showers and thunderstorms over Albay, Catanduanes, Camarines Norte, Camarines Sur, Sorsogon, and Masbate.
"'Yung tail-end of frontal system bagamat nakakaapekto pa rin sa Bicol region, unti-unting humihina ito, lumalayo sa ating bansa patungo sa central Pacific Ocean. (The tail-end of frontal system, although it still affects the Bicol region, is gradually weakening, moving away from our country towards the central Pacific Ocean)," Estareja said.
He explained that the tail-end of frontal system may no longer affect the country once the northeast monsoon also weakens.
The rest of the country will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms due to the easterlies.
"Base rin sa climate and monitoring section, mababa ang tsansa na magkakaroon tayo muli ng panibagong low pressure area o bagyo hanggang matapos ang linggong ito. (Likewise, based on the climate and monitoring section, chances remain low that we will have another low pressure area or tropical cyclone until the end of this week)," Estareja also said.
From Thursday until Saturday, March 25-27, he said Metro Manila will continue to experience hot and humid weather because it is highly likely that the hot and dry season will already begin in the country.
"Asahan pa rin naman yung localized thunderstorms or isolated rain showers sa hapon. (But still, expect localized thunderstorms or isolated rain showers in the afternoon)," Estareja said.
A gale warning was in effect on Wednesday due to "strong to gale force winds associated with the surge of northeast monsoon."
Rough to very rough seas may prevail across the eastern seaboards of Northern and Central Luzon, and eastern seaboards of Southern Luzon and Visayas.
Fishing boats and other small boats were advised not to venture out into these coasts, while, larger sea vessels were asked to remain alert against big waves.
