PAGASA is already monitoring not one, not two, but three low pressure areas on Tuesday, July 22

MANILA, Philippines – Metro Manila and five provinces in Central Luzon and Southern Luzon could have intense to torrential rain due to the southwest monsoon or habagat in the next 24 hours, the weather bureau said in an advisory shortly before noon on Tuesday, July 22.

The five provinces are Zambales, Bataan, Cavite, Batangas, and Occidental Mindoro. Along with Metro Manila, they were previously expected to have heavy to intense rain within 24 hours. Intense to torrential rain is the highest or most severe classification.

The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) also added more provinces to its rainfall outlook released at 11 am on Tuesday, including four in the Visayas — Antique, Iloilo, Guimaras, and Negros Occidental — which may now experience moderate to heavy rain earlier than previously predicted.

Here is PAGASA’s latest rainfall outlook for the next 72 hours:

Tuesday noon, July 22, to Wednesday noon, July 23

• Intense to torrential rain (above 200 millimeters): Zambales, Bataan, Metro Manila, Cavite, Batangas, Occidental Mindoro
• Heavy to intense rain (100-200 mm): Pangasinan, Benguet, Tarlac, Pampanga, Bulacan, Laguna, Rizal
• Moderate to heavy rain (50-100 mm): Ilocos Norte, Ilocos Sur, La Union, Abra, Nueva Ecija, Quezon, Oriental Mindoro, Palawan, Marinduque, Romblon, Masbate, Sorsogon, Albay, Camarines Sur, Catanduanes, Antique, Iloilo, Guimaras, Negros Occidental

Wednesday noon, July 23, to Thursday noon, July 24

• Intense to torrential rain (above 200 mm): Pangasinan, Zambales, Bataan
• Heavy to intense rain (100-200 mm): La Union, Benguet, Pampanga, Bulacan, Metro Manila, Cavite, Batangas, Laguna, Rizal, Occidental Mindoro
• Moderate to heavy rain (50-100 mm): Ilocos Norte, Ilocos Sur, Abra, Ifugao, Mountain Province, Nueva Vizcaya, Tarlac, Nueva Ecija, Quezon, Oriental Mindoro, Palawan, Marinduque, Romblon, Albay, Camarines Sur, Catanduanes, Antique

Thursday noon, July 24, to Friday noon, July 25

• Heavy to intense rain (100-200 mm): Ilocos Norte, Ilocos Sur, La Union, Pangasinan, Zambales, Bataan
• Moderate to heavy rain (50-100 mm): Apayao, Abra, Benguet, Tarlac, Pampanga, Bulacan, Metro Manila, Cavite, Batangas, Rizal, Laguna, Quezon, Occidental Mindoro, Oriental Mindoro, Marinduque, Romblon, Palawan, Antique

Areas with intense to torrential rain should again expect “widespread incidents of severe flooding and landslides,” warned PAGASA. This would add to the woes of residents who have been dealing with the effects of bad weather for days.

In the rest of the country on Tuesday, isolated to scattered rain and thunderstorms remain possible, still due to the southwest monsoon.

Malacañang suspended classes in all levels and government work in Metro Manila, Zambales, Bataan, Pampanga, Bulacan, Cavite, Batangas, Rizal, Pangasinan, Tarlac, and Occidental Mindoro.

Meanwhile, aside from the two low pressure areas inside the Philippine Area of Responsibility, PAGASA is now monitoring a new LPA outside PAR. It was located 2,850 kilometers east of Eastern Visayas as of 8 am on Tuesday.

The first and second LPAs were last spotted 1,140 kilometers east of Central Luzon and 225 kilometers east southeast of Basco, Batanes, respectively.

The LPA east of Central Luzon continues to have a high chance of developing into a tropical depression within 24 hours, while the other two have a “medium” chance.

The Philippines’ next tropical cyclone will be given the local name Dante.

PAGASA earlier said the trough or extension of the LPA east southeast of Basco is bringing scattered rain and thunderstorms to Cagayan Valley. The other two are still too far to directly affect any part of the Philippines.

So far, the country has had three tropical cyclones in 2025, two of them in July — Typhoon Bising (Danas) and Severe Tropical Storm Crising (Wipha). – Rappler.com
