A low pressure area formed but has no direct effect yet over any part of the country as of Saturday.
The Philippine Atmospheric, Geophysical, and Astronomical Services Administration said the LPA was about 920 kilometers east of Tuguegarao City around 3 p.m.
It is already inside the country’s area of responsibility but still hovers over the Philippine Sea.
PAGASA weather specialist Lorie dela Cruz said the LPA will move close to Northern Luzon within 24 to 36 hours but discounted the possibility of a landfall.
Instead, dela Cruz said the LPA may recurve back to the Philippine Sea.
As the LPA is still too far from the Philippine landmass, the intertropical convergence zone (ITCZ) and localized thunderstorms remain the dominant weather systems across the country Sunday.
PAGASA said the ITCZ may continue to bring cloudy skies with scattered rain showers and thunderstorms over Palawan, Zamboanga Sibugay, Zamboanga del Norte, and Zamboanga del Sur.
ITCZ is a region near the equator where winds from various directions converge, which is usually a breeding ground for localized thunderstorms, and sometimes potential LPAs.
Dela Cruz said the eastern portion of Mindanao that was earlier affected by the ITCZ will have improving weather by Sunday.
Meanwhile, warm mornings may lead to isolated afternoon or evening rain showers due to localized thunderstorms across Metro Manila and the rest of the country.
PAGASA advised the public to remain vigilant against possible flash floods or landslides in high-risk areas in the event of severe thunderstorms that usually occur from late afternoon to early evening.
