MANILA, Philippines 鈥� The northeast monsoon and shear line will bring rain to some parts of the country on Friday, December 6,聽the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) said.
In a 4 a.m. weathercast Friday, Pagasa specialist Benison Estareja said the two weather systems still influence atmospheric conditions nationwide, especially in the northern sections of Luzon.
鈥淒ahil sa northeast monsoon, asahan pa rin ang makulimlim na panahon at mahinang pag-ulan sa may Batanes. Habang ang shear line, nakakaapekto naman sa Cagayan, Isabela at malaking bahagi ng Cordillera Administrative Region,鈥� Estareja said.
(Expect cloudy skies and light rains in Batanes due to the northeast monsoon. While the shear line is affecting Cagayan, Isabela, and a huge portion of the Cordillera Administrative Region.)
鈥淚big sabihin magiging kalat-kalat pa rin 鈥榶ung mga thunderstorms dun kaya mag-ingat sa posibleng pagbaha at pagguho ng lupa,鈥� Estareja added.
(This means that scattered thunderstorms will occur there, so beware of possible flooding and landslides.)

A shear line occurs when the northeast monsoon 鈥� locally termed 鈥渁mihan鈥� 鈥� converges with easterlies or the warm winds coming from the Pacific Ocean, according to Pagasa.
Estareja also noted that the rest of Northern Luzon, particularly the Ilocos Region, will experience low temperatures and light rains due to the northeast monsoon.
Luzon鈥檚 central and southern portions, as well as Palawan and most parts of Visayas, especially the eastern section, will see moderate cloudy skies due to localized thunderstorms.
鈥淢adalas 鈥榶ung pag-ulan natin sa Quezon, Aurora, at dito rin po sa Bicol Region as early as this morning at mga pulo-pulo lang na ulan for Central and Southern Luzon,鈥� Estareja said.
(Rains will be frequent in Quezon, Aurora, and Bicol as early as this morning, while Central and Southern Luzon will experience scattered rains.)

鈥淪a Palawan at malaking bahagi ng Visayas, andyan pa rin ang bahagyang maulap at minsang maulap na kalangitan lalo na sa may eastern portion ng Visayas at sasamahan pa ito ng mga pulo-pulong pag-ulan usually nagtatagal ng isa o dalawang oras dahil sa localized thunderstorms pagsapit ng hapon,鈥� he added.
(Palawan and a huge portion of Visayas, especially the eastern portion of Visayas, will experience moderate cloudy skies with scattered rains that usually last for one to two hours due to the localized thunderstorms in the afternoon.)
For many areas in Mindanao, Estareja said the weather will be generally favorable on Friday, although moderately cloudy skies and rain are still anticipated to occur in some places of the region.
鈥淧agsapit ng hapon hanggang gabi, mas maraming lugar sa Mindanao lalo sa gitnang bahagi ang magkakaroon ng isolated rain showers or thunderstorms na usually hindi nagtatagal,鈥� he stated.
(By afternoon to evening, many areas in Mindanao, especially in the central portion, will experience isolated rain showers or thunderstorms that usually do not last long.)
The Pagasa expert also said that while no gale warning is raised over the country鈥檚 seaboards, coastal areas in Northern Luzon may experience moderate to rough seas due to the northeast monsoon.
