The southwest monsoon (habagat) alongside the extension of former Tropical Storm Krovanh (previously named Pilandok) will continue to bring rainfall across several areas in Luzon and the Visayas on Wednesday, September 9, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
In its 5 a.m. public bulletin, the state weather bureau reported that the habagat is currently influencing weather conditions in Central Luzon, Southern Luzon, and the entirety of the Visayas.
Overcast skies accompanied by scattered rain showers are expected across the Ilocos Region, Cordillera Administrative Region, Cagayan Valley, and Aurora as a result of Krovanh’s trough. Meanwhile, Metro Manila along with other sectors of Luzon will experience cloudy weather and monsoon rains.
Stronger wind gusts are anticipated along the western coastal and land areas of Luzon, particularly over Zambales, Bataan, Tarlac, Pampanga, Cavite, Batangas, and Occidental Mindoro.
PAGASA noted that heavy precipitation will persist over the country’s western corridor over the next three days. The monsoon is set to dump significant downpours over Ilocos Sur, La Union, Benguet, Pangasinan, Tarlac, Zambales, Pampanga, Bataan, Cavite, Batangas, and Occidental Mindoro.
Concurrently, the trough of Krovanh—which is operating outside the Philippine Area of Responsibility (PAR)—is bringing extension rains to Northern Luzon, particularly affecting Isabela, Quirino, and Aurora.
In the Visayas region, Palawan, Antique, and Aklan will see monsoon-driven rains. The rest of the Visayas and Mindanao can anticipate generally fair to partly cloudy conditions, though localized afternoon or evening thunderstorms remain likely due to hot and humid weather.
As of 3 a.m. Wednesday, PAGASA indicated that no low-pressure area (LPA) with cyclone potential was being monitored inside PAR. However, weather forecasters emphasized that the emergence of an LPA within the country’s boundary later in the week cannot be completely ruled out.
Rainfall coverage is projected to expand on Thursday due to the combined influence of the monsoon and Krovanh’s trough.
By Friday, September 11, forecasters are tracking the potential development of an LPA that could further intensify the habagat.
Authorities have warned residents in susceptible areas to maintain high vigilance for potential flash floods and landslides, given that previous days of continuous rainfall have already saturated the soil.
