MANILA, Philippines 鈥� Rain is expected over many parts of the country on Saturday, February 22 due to the effects of the northeast monsoon (amihan) and the shear line.
This is the forecast of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) said.
In the agency鈥檚 morning bulletin, specialist Benison Estareja said there was a high chance of weak to moderate rain showers in Northern Luzon, particularly Cagayan Valley, Cordillera Administrative Region and Aurora province due to the amihan.
Meanwhile, fair weather is expected in Metro Manila, Ilocos Region, the rest of Central Luzon and Calabarzon.
鈥淧agsapit ng hapon, madalas maulap ang kalangitan in some areas at mayroon lamang na maliit na chance ng mahinang pag-ulan,鈥� Estareja added.
(Then in the afternoon, the skies will be often cloudy in some areas and there would be only a small chance of weak rains.)
In Southern Luzon, Pagasa saw a high chance of rain showers and isolated thunderstorms, particularly Mimaropa, Bicol Region, Quezon, Batangas and Laguna due to the shear line.
The shear line is the area wherein the cold winds of the northeast monsoon and the warm winds of the easterlies 鈥� or winds from the Pacific Ocean 鈥� converge.
The shear line is also forecast to bring rains with thunderstorms in Palawan and Visayas, particularly Aklan, Capiz, the central and southern portions of Palawan, and many parts of Eastern Visayas.
鈥淧osible pa rin umabot between 50 to 100 millimeters ang dami ng mga pag-ulan,鈥� Estareja explained.
(The amount of rainfall may reach between 50 to 100 millimeters.)
Similarly, there is a high chance of rain in the Zamboanga Peninsula, Northern Mindanao, Caraga Region, Davao Region, as well as in the provinces of Basilan, Sulu, Tawi-Tawi, Dinagat Islands, Surigao del Norte and Surigao del Sur due to the shear line.
The areas in the Bangsamoro Administrative Region in Muslim Mindanao, as well as Soccsksargen, are expected to see rains as early as Saturday morning.
鈥淧ero hindi naman ito tuloy-tuloy at aasahan lamang yung mga isolated na ulan or mga thunderstorms for the rest of the day,鈥� Estareja said.
(But these rains won鈥檛 be continuous and expect only isolated rain showers or thunderstorms for the rest of the day.)
Pagasa has not monitored any tropical cyclones or low pressure areas within the Philippine area of responsibility.
鈥淢ayroon tayong mga kumpol ng ulap or cloud clusters somewhere dito sa may Mindanao and Palawan. Pero wala sa mga ito ang inaasahang magiging bagyo or low pressure area hanggang sa katapusan na ng Pebrero,鈥� Estareja explained.
(We have cloud clusters somewhere here over Mindanao and Palawan, but none of these are expected to become a tropical cyclone or a low-pressure area until the end of February.)
The state weather bureau did not raise a gale warning over the country鈥檚 seaboards.
However, rough sea conditions with waves between 2.8 and 4 meters are expected in the waters off Northern and Eastern Luzon.
Moderate to rough sea conditions with waves between 1.5 and 2.8 meters are expected in the waters off Western Luzon as well as in the eastern portions of Visayas and Mindanao.
Meanwhile, light to moderate sea conditions with waves between 0.6 to 2.5 meters are expected in the rest of the country.
