The southwest monsoon, or “habagat,” is expected to bring rain to western portions of Southern Luzon and the Visayas, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
In its 5 a.m. weather bulletin Saturday, PAGASA weather specialist Veronica Torres said Western Visayas, Occidental Mindoro, Oriental Mindoro, and Palawan will experience cloudy conditions with scattered rains and thunderstorms due to the southwest monsoon.
Torres warned that moderate to occasionally heavy rainfall could trigger flash floods and landslides in affected areas.
Meanwhile, the rest of the country may see isolated rain showers and localized thunderstorms, particularly over western sections of Luzon, including Metro Manila.
Generally light to moderate winds and slight to moderate sea conditions are also expected across the archipelago.
PAGASA is also monitoring two weather disturbances located outside the Philippine Area of Responsibility (PAR).
As of 3 a.m., Typhoon Dujuan, with the international name Dujuan, was located about 2,000 kilometers east-northeast of extreme Northern Luzon. It was packing maximum sustained winds of 120 kilometers per hour near its center and gustiness of up to 150 kph.
The typhoon was moving northwestward at 20 kph and is not expected to enter the PAR. Torres said it currently poses no direct threat to any part of the country.
A low-pressure area was also spotted around 140 kilometers south of Pag-asa Island in Kalayaan, Palawan.
Torres said the weather disturbance has a low probability of developing into a tropical cyclone within the next 24 hours.
