MANILA – The southwest monsoon or habagat will continue to affect Luzon on Tuesday, bringing occasional rains, scattered thunderstorms, and possible flooding and landslides in several areas, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said.

In its 4 a.m. 24-hour public weather forecast, PAGASA said Zambales, Bataan, and Occidental Mindoro will experience occasional rains due to the southwest monsoon.

Moderate to heavy rains may trigger flash floods or landslides in these areas, PAGASA warned.

Metro Manila, CALABARZON, Pangasinan, Benguet, Tarlac, Pampanga, Nueva Ecija, Bulacan, Marinduque, Romblon, Oriental Mindoro, and Camarines Norte may experience cloudy skies with scattered rains and thunderstorms.

The weather bureau likewise warned of possible flash floods or landslides due to moderate to at times heavy rains in these areas.

The rest of Luzon will have partly cloudy to cloudy skies with isolated rainshowers or thunderstorms due to the southwest monsoon.

Similar weather conditions are expected in the rest of the country due to localized thunderstorms, with severe thunderstorms potentially causing flash floods or landslides.

Meanwhile, the northern and western sections of Luzon will experience moderate to strong southwest winds, with coastal waters expected to be moderate to rough at 2.1 to 3.5 meters.

The rest of Luzon will have light to moderate southwest winds and slight to moderate coastal waters ranging from 1.2 to 2.5 meters.

Visayas and Mindanao will experience light to moderate winds from the south to southwest, with coastal waters ranging from 0.6 to 1.8 meters.

A tropical cyclone outside the Philippine Area of Responsibility was also monitored.

Tropical Storm Peilou (2616) was located 3,355 kilometers east of extreme Northern Luzon as of 3 a.m., with maximum sustained winds of 85 kph near the center and gustiness of up to 105 kph.

It was moving east-northeastward at 25 kph and was not directly affecting the country.

PAGASA advised the public to continue monitoring its weather updates, particularly those in areas prone to flooding and landslides.
