MANILA – Monsoon rains will continue to prevail over the western section of Luzon and the Visayas on Thursday.

In its 5 a.m. weather bulletin, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said this is due to the southwest monsoon and its trough enhanced by the tropical depression (formerly Caloy) that is now outside the Philippine Area of Responsibility (PAR).

Bataan, Zambales, Palawan, Oriental Mindoro, Occidental Mindoro, Aurora and Quezon will experience monsoon rains, while the rest of Luzon, and Western Visayas will have scattered rain showers and thunderstorms.

PAGASA said flash floods or landslides are likely in those areas due to scattered to widespread moderate to at times heavy rains.

Occasional gusty conditions reaching strong breeze to near gale in strength will prevail over extreme northern Luzon, and the western section of Luzon and the Visayas. These conditions are more likely in coastal and mountainous or upland localities.

The enhanced southwest monsoon will continue to cause moderate to rough seas over the seaboards of northern Luzon, and the western seaboards of central and southern Luzon. These conditions may be risky for small sea vessels. PAGASA advised mariners to take precautionary measures when venturing to the sea. If possible, avoid navigating in these conditions.

The rest of the country will have isolated rain showers caused by localized thunderstorms; with light to moderate winds and slight to moderate seas.

Meanwhile, Benison Estareja of PAGASA said a low pressure area (LPA) was spotted 1,020 kilometers east of northern Luzon.

This LPA is likely to develop into a tropical depression within 48 hours, and will be given the local name, "Domeng". (PNA)
