Two tropical cyclones outside the Philippine Area of Responsibility (PAR) continue to enhance the southwest monsoon (habagat) by pulling moist winds toward the land, bringing persistent rains over parts of western Luzon, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said on Monday, July 28.

PAGASA weather specialist Obet Badrina said Tropical Storm Co-may (formerly "Emong") was last located 985 kilometers northeast of extreme Northern Luzon, and is moving northwest toward China.

Meanwhile, the typhoon with the international name “Krosa,” located 2,455 kilometers east-northeast of extreme Northern Luzon, remains outside PAR and is not expected to enter the country’s monitoring domain.

However, Badrina said both weather disturbances are still enhancing the habagat, which continues to bring rains across several areas in western Luzon.

On Monday, moderate to heavy rains are expected to persist in Ilocos Norte, Ilocos Sur, La Union, Pangasinan, Abra, Benguet, Zambales, and Bataan.

Meanwhile, scattered light to, at times, heavy rains and thunderstorms may occur in Metro Manila, Cagayan Valley, Cavite, Laguna, Batangas, Rizal, Occidental Mindoro, Oriental Mindoro, the rest of Cordillera Administrative Region, and the rest of Central Luzon.

The rest of the country will experience generally fair weather with chances of isolated rains or thunderstorms in the afternoon and evening.

Badrina noted that weather conditions in most parts of Luzon are expected to gradually improve in the coming days, while generally fair weather is expected to persist in the Visayas and Mindanao.

However, localized thunderstorms remain possible during the late afternoon and evening, he added.

Badrina also said there is a low chance of tropical cyclone formation within the next four days.
