Scattered rain showers could continue to prevail over several parts of Luzon and Mindanao due to the presence of various rain-bearing weather systems in the country, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said on Saturday morning, Nov. 27.

The shear line, also known as the tail-end of the frontal system, may bring cloudy skies with scattered rain showers and thunderstorms over Batanes, Cagayan, Isabela, Quirino, Nueva Vizcaya, Apayao, Kalinga, Ifugao, Mountain Province, Aurora, and Quezon.

Scattered rain showers and thunderstorms may also prevail over Palawan, Zamboanga del Norte, Zamboanga del Sur, and Zamboanga Sibugay due to the intertropical convergence zone (ITCZ).

Areas that will likely be affected by the shear line and ITCZ were warned against possible flash floods or landslides, especially in the event of moderate to, at times, heavy rains.

Meanwhile, the northeast monsoon, locally called “amihan,” may cause partly cloudy to cloudy skies with isolated light rains over Ilocos Norte, Ilocos Sur, La Union, Pangasinan, Abra, Benguet, Bulacan, Tarlac, Pampanga, Bataan, Zambales, and Nueva Ecija.

PAGASA said Metro Manila and the rest of the country will have partly cloudy to cloudy skies with isolated rain showers due to the easterlies and localized thunderstorms.

The State weather bureau, however, warned that severe thunderstorm activities may sometimes trigger flash floods or landslides.

Likewise, a gale warning is in effect as of Saturday morning due to strong to gale-force winds associated with the northeast monsoon.

Wind associated with the northeast monsoon may bring rough to very rough seas over the northern, eastern, and western seaboards of northern Luzon.

PAGASA said fishing boats and other small seacrafts should not venture out into the sea while larger sea vessels should watch out for big waves.
