PAGASA monitors two LPAs as southwest monsoon brings heavy rain, thunderstorms
Key Takeaways
- •PAGASA is tracking two low pressure areas while the southwest monsoon brings heavy rain and thunderstorms to parts of the Philippines, heightening flood and landslide risks.
- •The closer LPA, positioned 1,040 kilometers west of Southwestern Luzon, has a medium chance of developing into a tropical depression within 24 hours.
- •The nearer system may steer the southwest monsoon away from the country, resulting in less rainfall over the mainland.
- •The farther LPA, located 2,875 kilometers east of Eastern Visayas, is unlikely to develop within 24 hours but may enter the Philippine Area of Responsibility over the weekend and move near Luzon.
- •Heavy rainfall of 50 to 100 millimeters is forecast only in Pangasinan, Zambales and Bataan until Saturday noon, with no heavy rainfall outlook issued for the weekend.
Two low pressure areas (LPAs) are being monitored as the southwest monsoon brings heavy rainfall to three areas and thunderstorms to parts of the Philippines, increasing the risk of flooding and landslides, the state weather bureau said on Friday.
The nearer LPA was located 1,040 kilometers west of Southwestern Luzon, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said in its 10:00 a.m. tropical cyclone formation outlook.
It has a medium chance of developing into a tropical depression within the next 24 hours. PAGASA said the system may steer the southwest monsoon away from the country, resulting in less rainfall over the mainland.
The farther and more recently formed LPA was located 2,875 kilometers east of Eastern Visayas. It is unlikely to develop into a tropical depression within the next 24 hours, PAGASA said.
The system may enter the Philippine Area of Responsibility (PAR) over the weekend and could move near Luzon.
Meanwhile, PAGASA’s 11:00 a.m. advisory said the southwest monsoon is expected to affect fewer areas over the next 24 hours.
Heavy rainfall, defined as between 50 and 100 millimeters, is expected only in Pangasinan, Zambales and Bataan until Saturday noon.
The southwest monsoon may also bring thunderstorms to Metro Manila, the rest of Luzon, Western Visayas and Northern Samar within the next 24 hours, PAGASA said in its 4:00 a.m. weather forecast.
