MANILA – Some parts of Luzon will experience rain showers caused by a low pressure area (LPA) and the northeast monsoon or "amihan," the weather bureau said Tuesday.

The LPA, last spotted 340 kilometers east northeast of Casiguran, Aurora or 345 km east of Tuguegarao City, Cagayan remains less likely to develop into a tropical cyclone.

However, it will bring scattered rain showers and thunderstorms over mainland Cagayan, Isabela, Aurora, and Quezon. Flash floods or landslides are possible due to moderate to heavy with at times intense rains, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said in its 4 a.m. weather bulletin.

Batanes and Babuyan Islands will experience rains caused by the northeast monsoon and flash floods or landslides due to moderate with at times heavy rains are also possible.

The amihan is forecast to bring light rains over Ilocos Region and Cordillera Administrative Region but no significant impact is expected.

The rest of the country will have isolated rain showers due to localized thunderstorms. Flash floods or landslides may be experienced during severe thunderstorms.

Meanwhile, moderate to strong winds and moderate to tough seas will prevail across Luzon.

The northern and western seaboards of Northern Luzon, the western seaboard of Central Luzon, and the northern and eastern seaboards of Luzon will have rough to very rough seas.

PAGASA advised fishing boats and other small seagoing vessels not to venture into the sea, and larger sea vessels are alerted against big waves.

Elsewhere, winds will be light to moderate with slight to moderate seas. (PNA)
