A low-pressure area (LPA) embedded in the Intertropical Convergence Zone (ITCZ) is expected to bring scattered rains and thunderstorms across large portions of the Philippines on Saturday, October 10, according to the state weather bureau.
In its 5 a.m. weather bulletin, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said the LPA was last spotted 310 kilometers east of Catarman, Northern Samar.
PAGASA weather specialist Veronica Torres said the weather disturbance has a low chance of developing into a tropical cyclone within the next 24 hours.
However, the combined effects of the LPA and ITCZ will bring cloudy skies with scattered rains and thunderstorms over Metro Manila, the Visayas, Mindanao, Bicol Region, Calabarzon, and Mimaropa.
Residents in these areas were advised to remain alert for possible flash floods and landslides, particularly during moderate to heavy rainfall.
Meanwhile, Batanes will experience cloudy skies with light rains due to the northeasterly windflow.
The rest of Cagayan Valley, Aurora, Nueva Ecija, and Bulacan will have cloudy skies with scattered rains and thunderstorms caused by the easterlies.
The remaining parts of Luzon will experience partly cloudy to cloudy skies with isolated rain showers or thunderstorms due to localized thunderstorms.
PAGASA is also monitoring two weather disturbances outside the Philippine Area of Responsibility (PAR).
One LPA was last located 2,260 kilometers east of southeastern Luzon and has a medium chance of developing into a tropical cyclone. However, it is not expected to enter PAR or affect the country.
Meanwhile, Typhoon Koguma was spotted 3,200 kilometers east of extreme Northern Luzon, carrying maximum sustained winds of 155 kilometers per hour (kph) and gusts reaching 190 kph.
The typhoon was moving west-northwestward at 25 kph.
Torres said Koguma is unlikely to enter PAR and is not expected to directly affect any part of the Philippines.
PAGASA urged the public to monitor official weather advisories and take necessary precautions against flooding, landslides, and thunderstorms.
