The Intertropical Convergenze Zone (ITCZ) continues to be the dominant weather system affecting the country, according to Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Monday.
PAGASA weather forecaster Samuel Duran said the ITCZ is now directly affecting Southern Luzon.
ITCZ, which is the thick clouds coming from the south of Asia, is considered a breeding ground for low-pressure areas (LPAs) or potential cyclones.
For Monday forecast, Duran said due to ITCZ it will bring cloudy skies with light to moderate rainshowers and thunderstorms over Metro Manila, Central Luzon, Calabarzon (Cavite, Laguna, Batangas, Rizal and Quezon) and Mimaropa (Mindoro, Marinduque, Romblon and Palawan).
He added the rest of the country will be partly cloudy to cloudy with isolated rainshowers or thunderstorms.
In its advisory, PAGASA said moderate to strong winds blowing from the northeast to northwest will prevail over Luzon and coming from the southwest over the rest of the country.
The coastal waters throughout the archipelago will be moderate to rough.
The weather bureau also issued a gale warning as the strong to gale force wind due to northeasterly windflow is affecting the northern and eastern seaboards of Northern Luzon.
“Fisherfolks and those using small seacrafts are advised not to venture out over the said seaboards,” PAGASA warned. PNA
