The trough or extension of a low pressure area (LPA) that was still outside the Philippine area of responsibility (PAR) could bring scattered moderate to heavy rains over the eastern portions of Visayas and Mindanao within 24 hours.
Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) weather specialist Loriedin dela Cruz estimated the location of the LPA at 1,345 kilometers east of Hinatuan, Surigao del Sur on Sunday morning.
It will likely enter the PAR within the day, she said.
Dela Cruz advised the public to continue monitoring updates regarding this weather disturbance, which has the potential to develop into a tropical depression in the coming days.
As of Sunday, the advancing clouds of the LPA will bring moderate to at times heavy rains over Biliran, Eastern Samar, Leyte, Southern Leyte, Northern Samar, West Samar, Agusan del Norte, Agusan del Sur, Dinagat Islands, Surigao del Norte, Surigao del Sur, Davao de Oro, Davao del Norte, Davao Oriental, Davao del Sur, and Davao Occidental.
The northeasterly surface wind flow, or the slight breeze coming from the northeast and a precursor of the “amihan,” may also bring moderate to occasional heavy rains over Aurora, Quezon, Abra, Benguet, Ifugao, Kalinga, Mountain Province, Apayao, Batanes, Cagayan, Isabela, Nueva Vizcaya, and Quirino.
Ilocos Norte, Ilocos Sur, La Union, Pangasinan, Bataan, Bulacan, Nueva Ecija, Tarlac, Pampanga, and Tarlac will have isolated light rains due to the northeasterly surface wind flow.
Meanwhile, Metro Manila and the rest of the country will be partly cloudy to cloudy but have a high chance of experiencing severe thunderstorms in the afternoon or evening.
A gale warning is in effect on Sunday over the eastern and western seaboards of Northern Luzon due to strong to gale force winds associated with the northeasterly surface wind flow, causing rough to very rough sea conditions.
PAGASA warned that sea travel is risky over these areas, especially for those using small boats.
