Fair weather with rain showers in parts of PH – Pagasa

MANILA, Philippines: Four weather systems – shear line, easterlies, northeast monsoon and localized thunderstorms – are affecting most parts of the country where isolated rain showers can be experienced, the state-run weather agency said on Friday.

The Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa) in its 5 a.m. advisory said, however, that the country could expect generally fair weather except for isolated downpours in the afternoon or at night.

Weather specialist Aldczar Aurelio told The Manila Times that they have not monitored any tropical cyclone or low pressure area inside or outside the Philippine Area of Responsibility in the coming days.

He said the shear line and easterlies are bringing overcast skies with scattered rain showers and thunderstorms over Aurora, Quezon, Oriental Mindoro, Marinduque, Romblon, Bicol Region, Aklan, Capiz, Northern Samar, Eastern Samar, Dinagat Islands, Surigao del Norte, Surigao del Sur and Davao Oriental.

The shear line is where the hot and cold air converge while easterlies are winds coming from the east that pass through the Pacific Ocean and carry warm and humid weather in the country.

On one hand, the northeast monsoon or «amihan» is affecting Cordillera Administrative Region, Cagayan, including Babuyan Islands, Isabela, Quirino, Ilocos Region and the rest of Cagayan Valley where cloudy skies with light rains will prevail within the next 24 hours, Pagasa said.

Meanwhile, the combined effects of the easterlies and localized thunderstorms will result in partly cloudy to cloudy skies with isolated rain showers or thunderstorms over Metro Manila and the rest of the country.
