The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) issued a weather advisory for Wednesday, December 3, 2025, warning of rains across several regions due to two dominant weather systems. The state weather bureau also monitors a low-pressure area with a high chance of turning into a tropical cyclone.
Dual Weather Systems Trigger Widespread Rains
According to PAGASA, the Intertropical Convergence Zone (ITCZ) is currently affecting southern Mindanao. This system is expected to bring scattered rain showers and thunderstorms over the provinces of Basilan, Sulu, and Tawi-Tawi.
Simultaneously, the northeast monsoon, locally known as amihan, will be influencing conditions in Northern and Central Luzon. Rains caused by the amihan are forecast to prevail in Cagayan Valley, Ilocos Norte, Apayao, Kalinga, and Aurora.
Potential Hazards and Extended Effects
PAGASA specifically cautioned residents in the affected areas. Moderate to heavy rains could lead to flash floods or landslides. The public is advised to take necessary precautions and stay updated with official announcements.
The effects of the northeast monsoon will extend to other areas, causing isolated light rains in the rest of the Ilocos Region, the rest of the Cordillera Administrative Region, and the rest of Central Luzon. For the remainder of the country, isolated rain showers caused by localized thunderstorms will persist.
Wind conditions will vary, with moderate to strong winds and moderate to rough coastal waters expected across Northern Luzon. Elsewhere, winds will be light to moderate with slight to moderate seas.
LPA Watch: Potential Tropical Cyclone Wilma
In a separate development, PAGASA is monitoring a low pressure area (LPA) located outside the Philippine Area of Responsibility (PAR). As of 2 a.m. on Wednesday, this weather disturbance was spotted approximately 1,210 kilometers east of southeastern Luzon.
The weather bureau stated that this LPA still has a high potential to develop into a tropical cyclone within the next 24 hours. Should it intensify into a cyclone and enter the PAR, it will be given the local name Wilma.
Authorities urge the public, especially those in areas under weather advisories and those involved in maritime activities, to remain vigilant and monitor further updates from PAGASA for any developments regarding the LPA and the ongoing weather systems.
