The southwest monsoon, locally known as habagat, will continue to bring rains and overcast skies across large portions of Luzon on Thursday, August 13, according to the state weather authority.
In its 5:00 a.m. public bulletin, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) reported that cloudy skies, scattered rain showers, and thunderstorms will prevail over almost all of Luzon.
The Bicol Region is largely excluded from this weather pattern, though Camarines Norte may still see localized, isolated rain showers.
Heavy rainfall will be concentrated over Zambales and Bataan, where a yellow heavy rainfall warning has been raised. Occasional rains are also forecast for Occidental Mindoro, while monsoon rains will extend to Palawan and portions of Western Visayas, particularly Aklan, Antique, and Capiz.
In contrast, the remainder of the Visayas and Mindanao can expect generally warm and humid conditions—especially during the afternoon—though brief, isolated downpours or thunderstorms remain possible.
Weather Conditions Breakdown
- Heavy Rains & Warnings: Zambales and Bataan (Yellow Heavy Rainfall Warning).
- Monsoon Rains & Showers: Occidental Mindoro, Palawan, Aklan, Antique, and Capiz.
- Overcast & Thunderstorms: Nearly all of Luzon (excluding most of Bicol).
- Generally Hot & Humid: Remaining areas of Visayas and Mindanao, with chances of localized afternoon thunderstorms.
PAGASA is also tracking Tropical Storm Nangka, which remains far outside the Philippine Area of Responsibility (PAR).
Located more than 2,500 kilometers east-northeast of extreme Northern Luzon, the storm is tracking northeastward at 20 km/h with maximum sustained winds of 65 km/h near its center and gusts reaching 80 km/h. Due to its distance, Nangka poses no direct threat to the country.
Disaster response authorities urge residents in vulnerable zones—particularly in Zambales, Bataan, and Occidental Mindoro—to stay vigilant against potential flash floods and landslides triggered by continuous rainfall.
