Multiple weather systems will affect the Philippines this Sunday, Nov. 8, as a convergence of three distinct meteorological forces dictates conditions across the archipelago. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) reported that the easterlies, the northeast monsoon, and a shear line are collectively driving a pattern of widespread cloudiness and precipitation, Cebu Daily News reported.
Easterlies and Shear Line Drive Regional Rainfall
The easterlies remain the most pervasive influence, bringing scattered rain showers and thunderstorms to a broad sweep of the country. According to the state weather bureau, this includes Eastern Visayas, Central Visayas, Caraga, Northern Mindanao, the Zamboanga Peninsula, and Davao Oriental. Metro Manila and the remaining regions are not spared, with partly cloudy to cloudy skies and isolated rains expected throughout the day.
The situation intensifies in Southern Luzon, where a shear line—the boundary where northeasterly and easterly winds collide—is active. This system is specifically targeting Aurora, Quezon, and Camarines Norte, resulting in scattered rains and isolated thunderstorms. The Daily Tribune noted that this localized concentration of heavy rain carries an elevated risk of flash floods and landslides, particularly in vulnerable communities within Quezon and parts of MIMAROPA, including Marinduque and Romblon. In Marinduque and Romblon, the easterlies are expected to cause moderate to occasionally heavy rainfall.
Amihan Brings Light Rains to Northern Areas
Simultaneously, the northeast monsoon, locally known as the amihan, is exerting its influence across the northern half of the country. This system is bringing light rains and cloudy skies to Cagayan Valley, Apayao, Kalinga, Mountain Province, and Ifugao. For the Ilocos Region, the remainder of the Cordillera Administrative Region, and Central Luzon, the forecast suggests partly cloudy to cloudy skies with isolated light rains. Pagasa noted that no significant impact is expected from these specific conditions.
Tropical Storm Cempaka Moves West-Northwest
Tropical Storm Cempaka, which intensified from a tropical depression at 8 a.m. on Saturday, remains outside the Philippine Area of Responsibility. As of 3 p.m. Saturday, the storm was positioned 2,175 kilometers east of Extreme Northern Luzon, packing maximum sustained winds of 65 kph and gusts reaching 80 kph. Pagasa is tracking the system as it moves west-northwestward at a speed of 30 kph.
The Daily Tribune reported that a separate tropical depression, also tracked by Pagasa, was located approximately 2,540 kilometers east of Northern Luzon as of 3 a.m. Saturday. This weather disturbance was moving west-northwestward at 30 kph and carried maximum sustained winds of 55 kph with gusts up to 70 kph.
Winds and Waves Affect Northern Coastal Waters
GMA Network reported that Northern Luzon is expected to face moderate to strong winds, with coastal waters turning moderate to rough. Wave heights in these northern sectors could reach between 1.5 and 4.0 meters. In contrast, the rest of the country can expect lighter conditions, with waves in Visayas and Mindanao ranging from 0.6 to 2.1 meters, and up to 2.5 meters in other parts of Luzon.
Pagasa’s warnings regarding flash floods and landslides remain the primary takeaway for residents in high-risk zones. Residents are encouraged to monitor official bulletins for updates, particularly as the shear line continues to influence rainfall intensity in Southern Luzon.
While the heat indices that prompted class suspensions in early November—such as the 42°C recorded in Cavite City and Mulanay, Quezon—have provided a recent backdrop of extreme warmth, the current shift toward widespread cloudiness and rain highlights the transition into a more monsoon-influenced period. The tropical storm Cempaka and the persistence of the amihan are key variables for the Philippine weather outlook.
Metro Manila Sunrise Occurs at 5:54 a.M
