(UPDATE) THE state-run weather agency said on Friday, March 15, that it has spotted cloud formations over Mindanao which are expected to bring rain in the area.

Weather specialist Benison Estareja of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) said, however, that these cloud clusters were unlikely to develop into a low pressure area.

He said four weather systems are currently affecting the country, namely, the northeast monsoon locally known as "amihan," shear line, easterlies, and localized thunderstorms.

Pagasa in its 5 a.m. advisory said the shear line, where the hot and cold air converge, is affecting Aurora, Quezon, and Camarines Norte where overcast skies with scattered downpours and thunderstorms would prevail.

Meanwhile, amihan is bringing isolated light rains over other areas in Northern Luzon including Batanes, Cagayan, Ilocos Region and Cordillera Administrative Region.

The combined effects of the easterlies and localized thunderstorms are affecting Metro Manila and the rest of the country where partly cloudy to cloudy skies with scattered rain showers or thunderstorms would be experienced within 24 hours, the state weather bureau said.
