As of 8:00 AM today, July 3, 2025, a low-pressure area (LPA) located within the Philippine Area of Responsibility (PAR) is being closely monitored. According to the latest update from DOST-PAGASA, this weather system currently has a medium chance of developing into a tropical depression within the next 24 hours. While it remains in its early stages, communities in its projected path are advised to stay alert for potential impacts, especially in terms of rainfall.
Meanwhile, Tropical Storm Mun continues to move outside the PAR but remains under observation by weather authorities due to its possible influence on the prevailing weather patterns in the region.
PAGASA’s Weather Advisory No. 6 highlights the expected rainfall associated with both the LPA and the enhanced southwest monsoon. Areas in Northern Luzon, including Cagayan, Batanes, Apayao, Abra, Kalinga, and Ilocos Norte, are expected to experience moderate to heavy rainfall through Sunday, July 6. Forecast totals may range from 50 to 200 millimeters, depending on location and time period, with heavier accumulations anticipated in elevated or mountainous areas.
The southwest monsoon is also forecast to bring significant rainfall to parts of Central and Southern Luzon, including Pangasinan, Zambales, Bataan, Occidental Mindoro, and surrounding provinces. Metro Manila and nearby areas may see rainfall amounts ranging from 50 to 100 millimeters over the same period.
PAGASA emphasizes that previous rainfall in some regions may worsen the impacts of the expected downpours. Flash floods, landslides, and localized flooding are possible, especially in low-lying and mountainous areas.
Residents and local disaster risk reduction and management offices are strongly advised to remain vigilant and to closely monitor updates from PAGASA. The agency may issue localized Heavy Rainfall Warnings or Thunderstorm Advisories as necessary, based on real-time data and radar monitoring.
It’s important to distinguish between a Weather Advisory and a Heavy Rainfall Warning. While a Weather Advisory provides a 24-hour outlook for broad areas such as provinces, Heavy Rainfall Warnings offer more immediate, location-specific updates for the next three hours and are crucial for time-sensitive decision-making in flood-prone municipalities.
Unless significant developments occur, the next official weather advisory will be released at 5:00 PM today. For the latest and most accurate information, the public is encouraged to follow updates from DOST-PAGASA and heed local advisories accordingly.
