Three weather systems–namely the intertropical convergence zone (ITCZ), shear line or tail-end of frontal system, and northeast monsoon or “amihan”–are currently affecting parts of Luzon and Mindanao, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said on Sunday morning, Nov. 14.

PAGASA said the prevalence of the ITCZ may cause cloudy skies with scattered light to, at times, heavy rains and thunderstorms over Palawan, Zamboanga del Norte, Zamboanga del Sur, and Zamboanga Sibugay in the next 24 hours.

Residents in these areas are advised to take precautions against possible flash floods or landslides due to occasional moderate to heavy rains.

Moreover, cloudy skies with light rains may persist over Batanes and Cagayan due to the shear line and amihan.

Partly cloudy to cloudy skies with isolated light rains may also prevail over Ilocos Region, Cordillera Administrative Region, and the rest of Cagayan Valley due to the northeast monsoon.

Meanwhile, Metro Manila and the rest of the country may continue to have partly cloudy to cloudy skies with isolated rain showers or thunderstorms due to localized thunderstorms.

PAGASA also advised those that may experience severe thunderstorms to remain vigilant against possible flash floods or landslides.

Likewise, a gale warning is currently in effect on Sunday due to strong to gale-force winds associated with the northeast monsoon, causing rough to very rough seas over the northern seaboards of northern Luzon, particularly over the seas of Batanes and Babuyan Islands.

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.
