A low-pressure area (LPA) inside the Philippine Area of Responsibility (PAR) will likely bring “significant rainfall” over the Visayas, Mindanao, and parts of Southern Luzon this weekend, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) warned on Friday, Sept. 12.
As of 3 a.m., the LPA was spotted 540 kilometers east of Hinatuan, Surigao del Sur.
Its trough or extension is already bringing scattered rains and thunderstorms over Eastern Visayas, Caraga, and Davao Oriental.
“Although its chance of developing into a tropical depression in the next 24 hours remains low, we are not discounting the possibility of intensification beyond that period,” PAGASA weather specialist Loriedin de la Cruz-Galicia said.
She explained that PAGASA is monitoring two possible scenarios: the weather disturbance may cross the Visayas and Mindanao as an LPA, or it may strengthen into a tropical cyclone before reaching land.
Regardless of its development, the LPA is expected to bring significant rainfall to affected areas this weekend, de la Cruz-Galicia said.
In addition, the easterlies, or warm winds from the Pacific Ocean, may continue to affect Aurora and Quezon, bringing cloudy skies with scattered rain showers and thunderstorms.
Metro Manila, the rest of Luzon, and the rest of the Visayas may also experience partly cloudy to cloudy skies with isolated rain showers or thunderstorms, while localized thunderstorms are likely over the rest of Mindanao.
PAGASA urged the public to stay alert for possible flash floods and landslides, especially during moderate to heavy rainfall or severe thunderstorms.
These thunderstorms typically last up to three hours and may bring intense rain, strong winds, lightning, and sometimes hail.
