MANILA — The interaction between a shear line impacting Central Luzon and a northeasterly wind pattern affecting Northern Luzon is expected to result in partially cloudy skies with isolated rainfall across most areas of the Philippines, according to the latest report from the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) released on Friday (20 Oct 2023).

The shear line is the weather system formed when cold and warm winds converge.

PAGASA’s 4 a.m. weather bulletin indicates that Batanes, Cagayan, Isabela, Apayao, and Kalinga should anticipate overcast conditions with showers due to the influence of the northeasterly wind flow. In the Ilocos region, as well as the rest of the Cordillera region and Cagayan Valley, the prevailing weather will be a mix of partly cloudy to cloudy skies with sporadic light rain.

For Metro Manila and the remainder of the country, the forecast calls for partly cloudy to cloudy conditions with isolated rain showers or thunderstorms, primarily attributed to the shear line and localized thunderstorms, as per PAGASA.

Expect moderate to strong winds with moderate to rough coastal waters in Luzon, while the rest of the country will experience light to moderate winds and slight to moderate sea conditions.

The temperature in Metro Manila will range from 24°C to 29°C; Baguio City, 17°C to 24°C; Laoag City, 25°C to 32°C; Legazpi City, 25°C to 32°C; Metro Cebu, 26°C to 31°C; Puerto Princesa City, 25°C to 32°C; and Metro Davao, 25°C to 33°C.
