The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Monday, Feb. 24 said the effect of the shear line—formed by the collision of cold winds from the northeast monsoon (amihan) and warm breezes from the Pacific Ocean (easterlies)—has weakened. However, rains may still affect several areas due to other prevailing weather systems.
PAGASA Weather Specialist Rhea Torres said that while the shear line is no longer affecting any parts of the country, the easterlies will bring cloudy skies, scattered rain showers, and thunderstorms to Eastern Visayas, Central Visayas, Negros Island Region, Caraga, Sorsogon, Masbate, Capiz, Iloilo, Davao Oriental, and Davao de Oro.
Residents in these areas are advised to remain vigilant against possible flash floods or landslides, especially during moderate to heavy rainfall.
Meanwhile, the amihan will cause cloudy skies and light rains across Cagayan Valley, Cordillera Administrative Region, and Aurora.
Partly cloudy to cloudy skies with isolated light rains due to the amihan may also affect Metro Manila, Cavite, Laguna, Batangas, Rizal, Quezon, Ilocos Region, and the rest of Central Luzon.
The rest of the country will experience partly cloudy to cloudy skies with isolated rain showers or thunderstorms.
Torres said the amihan's effect will strengthen further and bring more rain to eastern Luzon in the next two days. By Thursday, Feb. 27, its effect is expected to slightly weaken.
Before the end of the week, expect clearer weather in most parts of the country, she added.
