Heavy rains are expected to continue hammering large parts of Luzon on Tuesday as a low pressure area off the western coast interacts with the southwest monsoon, locally known as “habagat,” the state weather bureau reported.
According to the 4 a.m. bulletin from the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the low pressure area was located 210 kilometers west southwest of Cubi Point, Subic Bay or 290 kilometers west of Ambulong, Tanauan City, Batangas as of 3 a.m.
The system has a medium chance of intensifying into a tropical cyclone within the next 24 hours.
Luzon braces for more rains, flash flood threats
Scattered rains and thunderstorms are forecast to persist over Pangasinan, Zambales, and Bataan due to the combined effects of the LPA and the habagat. PAGASA noted that rainfall may become moderate to heavy at times and could trigger flash floods or landslides, especially in low-lying and mountainous areas.
Metro Manila, Calabarzon, the Bicol Region, Mimaropa, Western Visayas, Zamboanga Peninsula, and the remaining parts of Central Luzon are also experiencing continued downpours brought by the southwest monsoon.
Weather authorities urge residents in vulnerable areas to stay alert, especially with saturated soil increasing the risk of slope failure and sudden flooding.
Wider impact expected as storm threat increases
Elsewhere in the country, PAGASA warned of localized thunderstorms that could still cause isolated rain showers and short bursts of strong winds. Despite the absence of a fully formed storm, the weather bureau emphasized that this system already has significant potential to affect travel, agriculture, and daily activity in affected areas.
Mariners and small vessels were also advised to be cautious. Light to moderate winds and slight to moderate sea conditions continue to prevail across the archipelago, but sudden shifts in weather remain possible as the LPA develops.
While no tropical cyclone warning signal has been raised, forecasters remain closely monitoring the disturbance. If the LPA intensifies into a tropical depression, it could increase rainfall over a wider region and prolong the severe weather in affected provinces.
The public is urged to monitor official updates and follow local government advisories, especially as the system’s development remains uncertain but increasingly threatening.
Communities in low-lying coastal towns have already begun preparations for possible evacuation, anticipating another wave of intense rains by nightfall.
