MANILA - Several weather systems outside the Philippine area of responsibility will continue to enhance the southwest monsoon (habagat) and bring occasional rains in Luzon, state weather bureau PAGASA said.

In its 4 p.m. weather advisory, PAGASA said a low pressure area (LPA) has developed inside PAR. It was last located 920 kilometers east northeast of Basco, Batanes.

PAGASA weather specialist Ariel Rojas said the LPA is expected to dissipate within the next 12 hours.

Outside PAR, severe tropical storm Leepi, tropical depression Yagi (formerly Karding) and tropical storm Bebinca are all enhancing the southwest monsoon affecting the country.

As of 6 p.m., yellow rainfall warning was raised over Metro Manila, Bataan, Zambales and Bulacan. Heavy rains may cause flooding in flood-prone areas.

Light to moderate with occasional heavy rains are also expected in Nueva Ecija, Tarlac, Pampanga and Quezon, which may persist within two to three hours, while light to moderate with occasional heavy rains are expected over Cavite, Rizal, Laguna and Batangas within the next three hours.

Monsoon rains will persist over Ilocos region, Cordillera Administrative Region, Batanes, Babuyan Group of Islands, Zambales, Bataan, and Occidental Mindoro due to the effects of habagat.

Meanwhile, Metro Manila and the rest of Central Luzon and CALABARZOn will experience occasional rains, while partly cloudy to cloudy skies with isolated rains or thunderstorms are expected over the rest of Luzon.

Partly cloudy to cloudy skies with isolated rainshowers are also expected over Visayas and Mindanao.

PAGASA, likewise, warned residents in flood and landslide-prone areas to remain vigilant.

Rough to very rough coastal waters are also expected in the western and northern sections of Luzon, while oderate to rough coastal waters due to moderate to strong winds are also expected in the rest of the country.

Different parts of the country experience heavy rains and flooding over the weekend, leaving behind two people dead with another person missing.

• 2 dead, 1 missing in storm-enhanced habagat rains

This has also prompted several local government officials to suspend classes.
