Overview: Trough of Low Pressure Adds Rain Across Luzon
A trough of a low pressure area (LPA) coupled with a prevailing southwest windflow is expected to bring cloudy skies, scattered rains, and thunderstorms to several parts of Luzon and nearby regions. PAGASA’s early Saturday forecast indicates that Metro Manila, Zambales, Bataan, Cavite, Batangas, and Occidental Mindoro are most at risk for unsettled weather today, with occasional downpours and brief gusts possible.
The LPA was last tracked at 2 a.m. about 445 kilometers west of Pag-asa Island in the West Philippine Sea. At this stage, forecasters do not anticipate development into a tropical depression within the next 24 hours. Nevertheless, the trough remains a key driver of rain coverage in the region, and residents should stay alert for localized weather changes.
Which Areas Should Expect Rain?
Forecasts indicate two main weather drivers in play: the LPA trough and the southwest monsoon (southwesterly windflow). The trough is likely to keep skies cloudy with scattered rain showers and thunderstorms across Metro Manila, Zambales, Bataan, Cavite, Batangas, and Occidental Mindoro. These areas may experience bursts of rain that could affect travel, outdoor activities, and daily planning.
Meanwhile, the southwesterly windflow is expected to bring cloudy skies and rainfall to Palawan, Western Visayas, Negros Island Region, Zamboanga Peninsula, and parts of the Bangsamoro (BARMM). Rain events in these areas may be less intense than in Luzon’s main urban centers but can still disrupt commutes and local outdoor events.
Localized Thunderstorms and Weather Variability
Beyond the broad bands of rainfall, localized thunderstorms are anticipated across most of the country. These storms can appear with little warning, accompanied by brief heavy downpours, lightning, and gusty winds. If you are outdoors, seek shelter during storms and avoid tall trees, open fields, and exposed hilltops.
Wind and Coastal Conditions
Winds and coastal waters are expected to be moderate in Extreme Northern Luzon, with the rest of the country experiencing light to moderate winds and slightly rough coastal waters at times. Mariners and coastal communities should monitor weather updates and be prepared for possible sea conditions changes, especially if planning sea travel or fishing activities.
Practical Tips for Residents
- Check daily weather updates from PAGASA and local government advisories.
- Plan outdoor activities with flexible timing to accommodate sudden showers.
- Ensure drainage around homes is clear to reduce minor flooding risk in low-lying areas.
- Keep emergency kits ready and remember to stay indoors during thunderstorms.
- If driving, use headlights in rain, reduce speed, and maintain a safe following distance.
What to Expect Next
Forecasts suggest the LPA trough will continue to influence rain patterns across the region for the next 24 to 48 hours, with rainfall intensity varying by location. While not anticipated to develop into a tropical cyclone imminently, the system’s presence means periodic showers and thunderstorms are likely to persist. Weather monitoring will continue, and updates will reflect any shifts in timing or coverage of rain and wind.
Stay Prepared and Informed
As Luzon and nearby areas face cloudy skies and scattered rains, staying informed is essential. Local authorities will issue warnings and advisories as needed, and residents are encouraged to tailor plans to current conditions. By remaining vigilant and prepared, communities can mitigate weather-related disruptions and stay safe during the wet season.
