Rainy New Year's Eve expected for most of PH due to three weather systems

Pagasa forecasts that most of the Philippines will experience a rainy New Year's Eve due to three weather systems: a shear line, easterlies, and the northeast monsoon.

Camarines Norte, Camarines Sur, and Catanduanes will have cloudy skies with scattered rains and isolated thunderstorms due to the shear line.

The Visayas, Palawan, and the rest of the Bicol Region can expect overcast skies with scattered rains and thunderstorms from the easterlies.

Mindanao and the rest of Mimaropa will also have partly cloudy to cloudy skies with isolated rain showers or thunderstorms, also due to the easterlies.

Metro Manila and the rest of Luzon will have slightly cloudy to cloudy skies with isolated light rains from the northeast monsoon, locally known as amihan.

However, thunderstorms are less likely to develop over Metro Manila and nearby provinces within the next 12 hours, according to a revised advisory from Pagasa.

Pagasa is not currently monitoring any low-pressure areas that could develop into a tropical cyclone.
