The Shear Line would affect the eastern section of Luzon, and the Northeast Monsoon would affect the rest of the island group, weather service PAGASA reported in a Friday afternoon forecast.
Mainland Cagayan, Isabela, Aurora, Quezon, Camarines Norte, and the Kalayaan Islands would experience cloudy skies with scattered rain showers and thunderstorms because of the combined effects of the Shear Line and the trough of a low-pressure area.
The Northeast Monsoon would bring cloudy skies and rain over Metro Manila, the Cordillera Administrative Region, the rest of Cagayan Valley, Ilocos Norte, Ilocos Sur, Cavite, Laguna, and Rizal, and partly cloudy to cloudy skies with isolated light rains over the rest of Luzon.
Palawan, the Visayas, and Mindanao would experience cloudy to cloudy skies with isolated rain showers or thunderstorms because of the effects of the Easterlies and localized thunderstorms.
Meanwhile, Northern Luzon and the eastern sections of Central and Southern Luzon would experience strong winds with rough coastal waters, while the rest of Luzon and the eastern sections of the Visayas and Mindanao would have moderate to strong winds with moderate to rough seas.
The rest of the country may experience light to moderate winds with slight to moderate waters.
The sun would rise at 6:17 a.m. on Saturday. — DVM, GMA Integrated News
