The Ilocos Region, Benguet, Zambales, Bataan, and Occidental Mindoro are seeing the heaviest rainfall on Wednesday, July 28

Expect the southwest monsoon or hanging habagat to continue bringing on-and-off rain to parts of Luzon in the final days of July.

The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) has said that the southwest monsoon will remain the dominant weather system.

In an advisory issued at 11 am on Wednesday, July 28, PAGASA said rain will be experienced in these areas for the next 24 hours:

Moderate to heavy rain, with at times intense rain
  • Ilocos Region
  • Benguet
  • Zambales
  • Bataan
  • Occidental Mindoro
Light to moderate rain, with at times heavy rain
  • rest of Central Luzon
  • Metro Manila
  • Calabarzon
  • Batanes
  • Babuyan Islands
  • Apayao
  • Abra
  • northern part of Palawan including Kalayaan and Calamian Islands

“Under these conditions, scattered to widespread flooding and rain-induced landslides are possible during heavy or prolonged rainfall, especially in areas that are highly or very highly susceptible to these hazards,” PAGASA warned.

The state weather bureau added that regions and provinces affected by the southwest monsoon will have occasional gusty winds, especially in coastal and upland areas.

As of Wednesday morning, there is no potential tropical cyclone seen to affect the Philippines for the rest of July. There have been two tropical cyclones during the month: Tropical Depression Emong and Typhoon Fabian (In-fa). (READ: FAST FACTS: Tropical cyclones, rainfall advisories) –
