Moderate to heavy rains due to the trough or extension of a low pressure area (LPA) may persist over several areas within 24 hours, a weather forecaster said on Tuesday, Feb. 9.
Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) weather specialist Ezra Bulquerin said the LPA was at 75 kilometers east-southeast of Hinatuan, Surigao del Sur around 3 a.m.
Bulquerin noted that the LPA remains less likely to intensify into a tropical cyclone but will still bring significant rains over some parts of the country within 24 hours.
Moderate to heavy rains may still affect Cavite, Laguna, Batangas, Rizal, Quezon, Albay, Catanduanes, Camarines Norte, Camarines Sur, Sorsogon, Masbate, Bukidnon, Camiguin, Misamis Occidental, Misamis Oriental, Lanao del Norte, Agusan del Norte, Agusan del Sur, Dinagat Islands, Surigao del Norte, Surigao del Sur, Oriental Mindoro, Occidental Mindoro, Marinduque, Romblon, and Aurora.
Bulquerin said the northeast monsoon or "amihan" may also bring cloudy skies and moderate to heavy rains over Batanes, Cagayan, Isabela, Quirino, Nueva Vizcaya, Abra, Apayao, Benguet, Ifugao, Kalinga, and Mountain province.
PAGASA warned the public against possible flash floods or landslides triggered by moderate to heavy rains.
Ilocos Region will continue to be affected by the amihan but has no significant impact over the area, PAGASA said.
Isolated light amihan rains may be felt in Ilocos Norte, Ilocos Sur, La Union, and Pangasinan.
The rest of the country, including Metro Manila, may experience isolated rain showers caused by localized thunderstorms. PAGASA warned the public against severe thunderstorms that could trigger flash floods in low-lying areas or landslides in mountainous communities.
By Wednesday, Bulquerin said a gradual improvement in weather condition is likely in most areas that were affected by the LPA.
