Overcast skies, scattered rains to prevail on Wednesday (March 19)
MANILA, Philippines — Three weather systems are forecast to bring cloudy skies and scattered rains to many parts of the country on Wednesday, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) said.
In its morning weather bulletin, Pagasa identified these systems as the northeast monsoon or amihan, the shear line, and the easterlies.
“Today, the northeast monsoon continues to affect Luzon while the rest of the country remains under the effects of the easterlies,” state weather specialist Rhea Torres said in Filipino.
According to Torres, the shear line will bring cloudy skies with scattered rains and isolated thunderstorms over Eastern Visayas, Sorsogon, Masbate, Aklan, and Capiz.
Pagasa explained that the shear line is formed when warm easterlies converge with the cold northeast monsoon.
Meanwhile, the northeast monsoon will result in cloudy skies and rain over Cagayan Valley, Quezon, Aurora, Apayao, and the rest of the Bicol Region.
It will also set forth partly cloudy to cloudy skies with isolated light rains in Metro Manila and the rest of Luzon.

(So for today, rains will mostly be experienced in the eastern parts of the country. The eastern section of Luzon will see more rainfall due to the northeast monsoon,” she said.
The easterlies will bring cloudy skies with scattered rains and thunderstorms in Caraga and Davao Region.
The rest of the country will experience partly cloudy to cloudy skies with isolated rain showers or thunderstorms due to the same weather system.
“Rainy conditions are also possible due to the easterlies, which are warm winds coming from the Pacific Ocean,” Torres said.
The state weather bureau is not monitoring any low-pressure area or tropical cyclone inside or outside the Philippine area of responsibility as of Wednesday, March 19.
“However, due to the shear line, rainy weather is expected today until the weekend in many parts of the Visayas and Bicol Region,” she added.

Pagasa hoisted a gale warning over the western seaboard of Northern Luzon, particularly along the western coasts of Ilocos Norte and Ilocos Sur.
Torres warned that rough to very rough sea conditions are expected in these areas, with wave heights ranging from 2.8 to 4.5 meters.
