Shear line, easterlies bring rains, thunderstorms to Luzon; amihan hits Batanes

Three weather systems—the shear line, easterlies, and northeast monsoon (amihan)—will bring cloudy skies and rains to various parts of the Philippines on Sunday and Monday.

Metro Manila and other regions will see partly cloudy to cloudy skies with isolated rain showers or thunderstorms due to localized easterlies.

The shear line affecting eastern sections of Central Luzon and Northern Luzon, including the Cordillera Administrative Region, mainland Cagayan, Isabela, Nueva Vizcaya, Quirino, Aurora, Quezon, Camarines Norte, Camarines Sur, Catanduanes, Albay, and Ilocos Region, will bring cloudy skies with scattered rains and isolated thunderstorms, potentially leading to flash floods or landslides.

Caraga, Davao Region, Northern Mindanao, SOCCSKSARGEN, Eastern Samar, Leyte, Southern Leyte, and other affected areas may experience cloudy skies with scattered rains and thunderstorms due to the easterlies.

Batanes and Babuyan Islands will face partly cloudy to cloudy skies with isolated light rains from the amihan; PAGASA weather specialist Obet Badrina noted that the amihan is expected to weaken in the coming days.

PAGASA warned of potential flash floods or landslides in areas affected by the shear line and easterlies, especially during moderate to heavy rainfall.

Elsewhere, winds will be light to moderate with slight to moderate seas.
