MANILA, Philippines — The state weather agency PAGASA has projected that the southwest monsoon, locally known as the "habagat," will impact parts of Luzon on Wednesday, July 30. The weather system is expected to cause widespread rains across central and northern Luzon.

Residents in Metro Manila, Central Luzon, the remainder of the Cordillera Administrative Region, Cagayan Valley, and Rizal can expect cloudy skies accompanied by scattered rain showers and thunderstorms. The habagat will also bring intermittent rainfall to the Ilocos Region, Batanes, Babuyan Islands, Abra, and Benguet.

Authorities have issued warnings to communities in these areas about the potential for flooding and landslides resulting from moderate to heavy rainfall.

Apart from Luzon, the rest of the country is forecast to experience partly cloudy to cloudy conditions with isolated rainshowers or thunderstorms, influenced by the habagat.

PAGASA further reported that strong southwest winds will affect extreme Northern Luzon, leading to rough sea conditions with wave heights ranging from 2.8 to 4.0 meters. The western parts of Luzon will also experience moderate to strong southwest winds, producing moderate to rough coastal waters with waves between 2.1 and 3.4 meters.

Meanwhile, the other regions of the Philippines will experience light to moderate winds coming from the south to southwest, with coastal waters expected to be slight to moderate and wave heights from 0.6 to 2.1 meters.
