Expect rains over several areas in Luzon within 24 hours due to the combined impacts of a low pressure area (LPA) and the tail-end of the frontal system, the State weather bureau said on Wednesday.

According to the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA), the LPA northeast of Romblon, Romblon has already dissipated around 8 a.m. on Wednesday, but another one has developed east of Southern Luzon.

The new LPA was last spotted by PAGASA at 250 kilometers east of Virac, Catanduanes around 10 a.m. It is less likely to develop into a tropical depression in the next 24 hours. 

However, the prevalence of the tail-end of the frontal system and the LPA may cause moderate to heavy rains with at times intense rains over Isabela, Quirino, Aurora, and the eastern portion of Cagayan. 

Light to moderate with at times heavy rains may also affect Abra, Apayao, Benguet, Ifugao, Kalinga, Mountain Province, Cavite, Laguna, Batangas, Rizal Quezon, Nueva Ecija, Bulacan, Camarines Norte, the rest of Cagayan, Batanes, Isabela, and Nueva Vizcaya.

Flooding, including flash floods, and rain-induced landslides may occur during heavy or prolonged periods of rainfall, especially in areas that are highly susceptible to these hazards or have received a significant amount of rainfall during the past couple of days or weeks, PAGASA warned.

It also advised adjacent or nearby areas that may not have been directly affected by the rainfall to remain alert against possible flooding from surface runoff or swelling of river channels. 

The rest of the country will be partly cloudy to cloudy with isolated rain showers due to localized thunderstorms. Possible flash floods or landslides may also occur during severe thunderstorms, PAGASA said.

Strong to gale force winds associated with the surge of northeast monsoon or “amihan” could cause rough to very rough seas over the northern and western seaboards of Northern Luzon, and over the northern and eastern coastlines of Luzon.

Fishing boats and other small boats were advised against traveling out to sea, while larger sea vessels were asked to remain alert against big waves as travel over these waters may be risky.
