MANILA - The trough or extension of a low pressure area will dump rains over large swaths of Mindanao on Sunday, the state weather bureau said.
The LPA was some 3,000 kilometers east of Mindanao at 3 a.m., said PAGASA weather specialist Ariel Rojas.
For now, the weather system is unlikely to become a storm but it could still draw moisture from the Pacific Ocean and strengthen, he said in a phone interview with ABS-CBN News.
It may enter the Philippine area of responsibility on Thursday, he added.
The LPA's trough will bring occasionally heavy rains that may trigger potential floods and landslides in Northern Mindanao, Caraga and Davao regions, PAGASA said in an advisory.
Meanwhile, the amihan or northeast monsoon may bring light rains over Bicol region, Aurora and Quezon, said the weather agency.
The amihan will also cause partly cloudy to cloudy skies in Metro Manila, Visayas and the rest of Luzon,it added.
