The southwest monsoon or 'habagat,' will continue to bring scattered rains to the western sections of Luzon and the Visayas on Monday, July 20, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
In its 4 a.m. weather bulletin, PAGASA said the weak southwest monsoon is currently affecting the western portions of Luzon and the Visayas and may also extend its influence to the western section of Mindanao by Monday afternoon or Tuesday.
Cloudy skies with scattered rain showers and thunderstorms are likely to develop in the Monday afternoon and evening over the western sections of the country.
The Metro Manila, Ilocos Region, Bataan, Zambales, Cavite, Batangas, Occidental Mindoro, Oriental Mindoro, Palawan, Western Visayas, the Negros Island Region, Zamboanga Peninsula, the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM), Sultan Kudarat, and Sarangani will have cloudy skies with scattered rains and thunderstorms due to the southwest monsoon.
Fair weather is expected to prevail across most parts of the country during the Monday morning.
PAGASA said the southwest monsoon is expected to continue affecting the country over the next two to three days.
The weather bureau warned residents in these areas of possible flash floods and landslides during severe thunderstorms.
By Wednesday, July 22, the weather system is forecast to influence a larger portion of Southern Luzon, the Visayas, and Mindanao, bringing a higher chance of rain showers and thunderstorms in these areas.
Meanwhile, PAGASA said it is monitoring a cloud cluster with the potential to develop into a low-pressure area (LPA). However, the weather bureau said the cloud cluster is not expected to affect the country's weather at this time.
As of 2 a.m. Monday, PAGASA reported that no LPAs were being monitored inside or outside the Philippine Area of Responsibility (PAR) for possible tropical cyclone development.
No gale warning has also been issued, indicating that no rough sea conditions are expected over the country's coastal waters.
However, PAGASA advised fishermen and those planning to venture out to sea to remain cautious, especially during the afternoon and evening, when thunderstorms could develop and bring sudden changes in weather and sea conditions.
