Three weather systems could bring cloudy skies and rain showers across several parts of the country in the next 24 hours, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said in its weather bulletin on Tuesday afternoon, Nov. 23.

Batanes, Babuyan Islands, Cagayan, Isabela, and Apayao may experience cloudy skies with rains due to the northeast monsoon, locally called "amihan."

Meanwhile, the shear line, also called the tail-end of frontal system, may bring cloudy skies with scattered rain showers and thunderstorms over Laguna, Rizal, and the northern portion of Quezon including Polillo Islands.

Caraga, Davao Oriental, and Davao de Oro may have cloudy skies with scattered rain showers and thunderstorms due to the intertropical convergence zone (ITCZ).

PAGASA said those affected by the amihan, shear line, and ITCZ should stay vigilant against possible flash floods or landslides due to the occurrence of moderate to, at times, heavy rains.

Meanwhile, mostly fair weather conditions may persist across the rest of the country.

PAGASA said that Ilocos Region, Central Luzon, and the rest of Cagayan Valley, and Cordillera Administrative Region may have partly cloudy skies with isolated light monsoon rains.

Metro Manila and the rest of the country will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms.

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