PAGASA warns of flash floods, landslides in parts of Luzon due to LPA, southwest monsoon

A trough of a low pressure area (LPA) and southwest monsoon will affect parts of Luzon on Sunday, August 17, according to PAGASA.

Cloudy skies with scattered rains and thunderstorms are expected in the Ilocos Region, Apayao, Cagayan, Zambales, Bataan, Metro Manila, Cavite, Batangas, Occidental Mindoro, and Palawan due to these weather systems.

PAGASA warns of potential flash floods and landslides amid heavy rains and has advised residents in affected areas to take necessary precautions.

As of 2 p.m., the LPA inside PAR was located 600 kilometers northeast of Itbayat, Batanes with a medium chance of developing into a tropical depression within 24 hours and possibly named Juaning if it forms inside the Philippine area of responsibility.

Another LPA off southern China also has a high chance of developing into a tropical depression, which may pull the southwest monsoon away from the Philippines, resulting in much less rain.

Meanwhile, the trough of the LPA is affecting the western parts of Northern and Central Luzon and may bring scattered rain showers to Palawan, as well as Mindoro, Metro Manila, Cavite and Batangas.
