MANILA, Philippines – The state-run weather agency said Thursday that it has not monitored any low pressure area forming inside or outside the Philippine Area of Responsibility until the weekend while the ‘weakening’ northeast monsoon (‘amihan’) is only affecting Northern Luzon. In particular, the affected areas include Cordillera Administrative Region, Cagayan, Isabela, Quirino, Nueva Vizcaya, and Aurora at which cloudy skies with light rains would occur, said weather specialist Loriedin Dela Cruz-Galicia of the Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa) said. Amihan, which brings cool and dry winds, has also been affecting Ilocos Region and Batanes where partly cloudy to overcast skies with isolated light rains would prevail. Metro Manila and the rest of the country, meanwhile, would be experiencing partly cloudy to cloudy skies with isolated rain showers or thunderstorms owing to the effect of the localized thunderstorms, the national weather bureau said. As to the heat index outlook, the Pagasa forecaster said the highest temperature which can be recorded in the day would be in Cotabato City, Maguindanao at 41 degrees Celsius, which is at ‘extreme caution’ category, while 32 degrees Celsius to 34 degrees Celsius over Metro Manila.
