MANILA, Philippines —Parts of the country, including Metro Manila, will experience cloudy skies with isolated rain showers or thunderstorms on Wednesday due to two weather systems, the Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa) said. The easterlies and northeast monsoon (‘amihan’) are expected to bring scattered or isolated downpours within 24 hours, the state weather bureau said. Nathaniel Servando, Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa) chief, said amihan, which brings cool and dry winds, has resurfaced but will only be only affecting Batanes and Babuyan Islands in extreme Northern Luzon. Meanwhile, the easterlies – winds that pass through Pacific Ocean and carry warm and humid weather – has been prevailing over Surigao del Norte, Surigao del Sur, and Dinagat Islands where cloudy skies with scattered rains and thunderstorms were expected. The same weather system will also be experienced over Metro Manila and the rest of the country where partly cloudy to overcast skies with isolated rain showers or thunderstorms would prevail within 24 hours, the national weather agency said. Servando said flash floods or landslides may occur in the affected areas if the rains become moderate to heavy. No low pressure has been monitored in the next three days, Servando said, but added that Pagasa was monitoring the formation of a tropical cyclone.
