MANILA — A convergence of three weather systems is set to influence the weather across the Philippines, with expectations of cloudy skies and isolated rains, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

As of the 4 a.m. bulletin on Saturday, PAGASA reported that a shear line impacting the eastern part of Southern Luzon, the northeast monsoon prevailing over Luzon, and the easterlies affecting Visayas and Mindanao will collectively result in partly cloudy to cloudy conditions with sporadic rain showers across the archipelago.

The shear line is anticipated to bring cloudy skies accompanied by scattered rain showers and thunderstorms particularly over Quezon, Laguna, and the Bicol region. PAGASA issued warnings of potential flash floods or landslides in these areas during moderate to heavy rainfall.

Meanwhile, the northeast monsoon, locally known as “amihan,” is forecasted to induce cloudy skies with light rains over the Cordillera region, Cagayan Valley, and Aurora. Metro Manila, Calabarzon, Central Luzon, and the Ilocos region are expected to experience partly cloudy to cloudy skies with isolated light rains due to the same weather system.

For the rest of the country, partly cloudy to cloudy skies with isolated rain showers or thunderstorms are expected, attributable to the easterlies and localized thunderstorms.

PAGASA cautioned that severe thunderstorms could lead to flash floods or landslides in vulnerable areas.

In terms of wind and sea conditions, Luzon is anticipated to experience moderate to rough winds and moderate to rough coastal waters, while the Visayas and Mindanao will encounter light to moderate winds and slight to moderate seas.

Temperature ranges for selected areas are as follows: Metro Manila (24°C to 31°C), Baguio City (15°C to 25°C), Laoag City (23°C to 32°C), Legazpi City (25°C to 32°C), Metro Cebu (26°C to 32°C), Puerto Princesa City (26°C to 33°C), and Metro Davao (25°C to 33°C).
