Residents of Mindoro and the MIMAROPA region are bracing for cloudy skies and potential flooding as a low-pressure area (LPA) and the southwest monsoon bring scattered rainshowers and thunderstorms to the area, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

The weather bureau’s 24-hour forecast issued at 5:00 AM on Thursday warns of possible flash floods or landslides due to moderate to at times heavy rains across the region.

As of 3:00 AM, the LPA was located in the vicinity of Catbalogan City, Samar, approximately 300 kilometers east of Mindoro. 

While not directly over the MIMAROPA region, its effects are being felt in combination with the prevailing southwest monsoon.

In its Heavy Rainfall Warning No. 02 issued at 8:00 AM Thursday, July 18, 2024, PAGASA warned of potential flooding in low-lying areas and near river channels in Romblon. 

The weather bureau also reported moderate to heavy rains affecting Oriental Mindoro, Marinduque, and several provinces in the Bicol Region and Eastern Visayas.

Oriental Mindoro can expect temperatures ranging from 26°C to 29°C, with light to moderate easterly winds and slight to moderate coastal waters. 

Similar conditions are forecast for neighboring Marinduque, with temperatures between 25°C and 29°C.

PAGASA said: “While we’re not expecting severe weather, the combination of the LPA and monsoon can lead to sudden heavy downpours. Residents, especially in low-lying areas, should remain vigilant.”

Local disaster risk reduction and management offices across MIMAROPA are on alert. In Puerto Princesa, Palawan, officials have begun reviewing evacuation plans and checking relief supplies.

The weather system is also affecting other parts of the country. 

The Visayas, Bicol Region, and parts of Luzon are experiencing similar conditions, with the trough of the LPA bringing cloudy skies and scattered rainshowers to eastern portions of Luzon.

For Metro Manila and other parts of Luzon not directly affected by the LPA, the southwest monsoon is the primary weather factor, bringing cloudy skies with a chance of rainshowers and thunderstorms.

PAGASA advises the public to monitor weather updates and follow local authorities’ instructions. Farmers and fishermen are urged to take necessary precautions.

The weather bureau expects conditions to improve gradually over the weekend as the LPA moves away from the Philippine Area of Responsibility. 

However, intermittent rains due to the southwest monsoon may persist in the western sections of the country.
