The low pressure area (LPA) southwest of Mindanao has already dissipated but a new LPA has formed in Eastern Visayas on Tuesday morning.
The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) last spotted the LPA in the vicinity of Borongan City, Eastern Samar at around 10 a.m.
In the next 48 hours, the LPA has a slim chance of developing into a tropical depression but will likely traverse the Southern Luzon-Visayas area, PAGASA said.
The combined effects of the LPA and the tail-end of the frontal system may bring moderate to heavy rains with at times intense rains over Eastern Samar, Northern Samar, Catanduanes, and northeastern portion of Camarines Sur within 24 hours.
Moderate to heavy rains may also prevail over Marinduque, Romblon, southern portion of Quezon, and the rest of Bicol region and Eastern Visayas.
Light to moderate with at times heavy rains may affect Oriental Mindoro, Occidental Mindoro, Aklan, Antique, Capiz, Guimaras, Iloilo, Negros Occidental, northern portion of Cebu, and the rest of Quezon province.
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, PAGASA warned.
Likewise, it said adjacent or nearby areas that may not have been directly affected by the rainfall were urged to remain alert due to the possibility of flooding from surface runoff or swelling of river channels.
The northeast monsoon or "amihan" may bring cloudy skies with scattered rain showers and thunderstorms over the rest of Luzon, while the rest of the country will have isolated rain showers due to localized thunderstorms.
Due to the surge of amihan, sea travel remains risky over the northern, western, and eastern seaboards of Northern Luzon and Central Luzon, western and eastern seaboards of Southern Luzon, and eastern coastlines of Visayas and Mindanao.
Fishing boats and other small sea vessels were advised against traveling out to sea, while larger sea vessels were asked to remain alert against big waves due to risky sea travel over these waters.
